THIS KIT INCLUDES A SET OF YORKER CAPS FOR CONTROLLED DISPENSING.

Use these Yorker caps to dispense the material with ease and minimize over pouring and reduce spills. These dispensing caps are low cost yet effective alternative to pumps which allows moisture and carbon dioxide.

The amine curing agent of any epoxy resin system is sensitive to moisture and carbon dioxide.

The reaction forms carbamate crystals (salt-like crusts that form at the tip of the pump or bottle opening) that reduces reactivity.  Carbamate crystals form on the pump opening when the curing agent has exposed to ambient moisture and carbon dioxide.  The crystals are insoluble in epoxy resin resulting in contamination and causes poor cure and amine-blushing.  The carbamate crystals stays solid mixed with the PART A resin component and cause FOD or foreign object debris in the resin mixture.

RESIN CRYSTALLIZATION FROM PROLONGED STORAGE OR COLD WEATHER EXPOSURE

The resin component or the PART A may crystallize due to cold temperature exposure. 

Please inspect the resin component for any solidified crystals which will appear as waxy solid or cloudiness on the bottom of the PART A bottle.

Proper Usage Data And Other Detailed Information Are Posted At This Page Mix the Resin And Curing Agent Only After The Surface Is Prepared For Application

STEP 1. SURFACE PREPARATION The quality of adhesion of any coating or adhesive application is dependent on how well the surface is prepared.  The resin system must be able to properly 'wet-out' the surface to form a continuous film. Surfaces demonstrating poor wettability prevents the liquid resin from forming a cohesive bond. Improper surface wetting yields poor adhesion and will delaminate during use. Wetting is the ability of a liquid to interfaces or wet-out a solid surface; its dynamics is expressed as surface tension.

Low surface tension surfaces, such as oily surface or slick plastics like Teflon prevents the liquid resin to wet-out the surface and cause poor adhesion. In the same respect, if the surface is coated from a previous application, the epoxy adhesion is limited to adhesion quality of the primary coating is applied over. Make sure to remove any loose or peeling old coating before application to avoid delamination. If possible remove the old coating by mechanical sanding or power washing so the applied epoxy is in direct contact with the base substrate. Poor Wetting (Crawling) Due To Oil-based Stain Applied On Wood Applying a coating over a painted, treated or contaminated surface can cause the epoxy coating to retract into a discontinuous application. This phenomenon is called 'crawling' which indicates that the surface is low in surface tension making it difficult for the liquid coating to wet-out the surface. The poor wetting or hydrophobicity is commonly caused by oils-based wood stains and other wood treatments.

[isdntekvideo] This hydrophobic characteristic is commonly seen in nature when leaves repel water that keeps the surface dry. Testing And Preparing The Surface To Improve Wetting And Eliminate Crawling Coating Defects With proper surface preparation, such as light sanding and solvent cleaning, the surface tension will increase, making it wettable, and epoxy coating can be applied with no film crawling.

Surface Preparation Procedures

METALS AND CONCRETE

Degrease Metals– Wipe surface with a lint-free rag dampened with Methyl Ethyl Ketone (MEK) or acetone to remove all oil, dirt, and grease. Degrease Concrete- Use 2 cups of TSP (trisodium phosphate) detergent per 5 gallons of hot water and scrub with a stiff deck brush. Rinse with water and allow to dry.

Etch Metals – For optimum results, metal parts should be immersed in a chromic acid bath solution consisting of:

Sodium Dichromate

4 Parts By Weight

Sulfuric Acid

10 Parts By Weight

Water

30 Parts By Weight

The solution is held at 160°F (71°C), and the parts left immersed for 5 to 7 minutes. Rinse – remove metal parts from etching bath and rinse with clean water. (distilled water is recommended).

Etch Concrete- Use commercially sold concrete etching solution (hydrochloric acid based works best). Neutralized per instructions, rinse and allow to dry thoroughly.

ALTERNATE PROCEDURE  Degrease, scour and dry – Often etching as outlined above is not practical. The metal surfaces may be cleaned by degreasing as noted above, scouring with an alkaline cleanser followed by rinsing and drying.

Degrease and dry – Degrease the surface as noted above, sand or sandblast the surface lightly but thoroughly. Rinse with acetone or Methyl Ethyl Ketone (MEK), and dry.

GLASS

Degrease – With MEK as above, or with a strong boiling solution of a good grade household detergent.

Etch – For optimum results, degreasing can be followed by the chromic acid bath outlined above.

WOOD

Sand – Bonding surfaces should be sanded lightly, but thoroughly to remove all external contamination.

Clean – Carefully remove all dust, or particles of wood from sanded areas. A stiff and clean brush or compressed air can be used.

PLASTIC

Clean – Remove all dirt, oil, or other surfaces contaminated with detergent soap or degreasing solvent and water, followed by thorough rinsing and drying. A solvent that does not have a detrimental effect may also be used.

Sand – Surfaces to be bonded should be sanded lightly, but thoroughly to remove surface sheen.

Clean – Carefully remove all dust or particles of plastic from the sanded area. A clean brush, lint-free cloth, or compressed air may be used.

STEP 2. CHECK THE PART A OR RESIN BOTTLE FOR CRYSTALLIZATION During the winter months, the PART A or RESIN component may crystallize and cause poor cure performance. Our MAX Epoxy Resins are formulated with high purity grade resin polymers which makes it prone to crystallization when exposed to temperatures below 57°F. Crystallization can also occur after the resin has been stored over a period. It appears as a waxy white mass at the bottom of the bottle. The PART A or RESIN component must be in its liquid form to thoroughly mix with the PART B or curing agent to achieve full cure. 

DO NOT USE UNLESS PROCESSED View the following video for identification and processing.

STEP 4. MIXING PROCEDURE The two components must be mixed thoroughly to eliminate problems such as tacky or uncured spots.  Use the "two container method" as demonstrated in this video demonstration, which ensures a homogeneous mixture of the resin and curing agent.

What Is 'Grain Raising'?

When a liquid coating is applied over wood, fibers will begin to swell, and this will produce 'grain raising' to occur. Raised grains are small end fibers protruding from the coating causing unsightly unevenness. Allow the applied resin to cure for 18 to 24 hours and lightly sand the surface using fine-grit sandpaper. Remove dust and debris by wiping with a lint-free rag dampened with alcohol or acetone and allow to dry.

Once the surface is prepared, apply the second coat of MAX CLR which will yield a smooth blemish free coating. ROTO-COATING OF MAX CLR ON WOOD TURNED BOWL Click Play To Watch Video Demonstration At Our YouTube Channel

STEP 6. CURING To achieve the best cure results, the ambient condition should be between 75°F to 85°F and the relative humidity is below 80%. The colder the temperature the longer takes to fully cure. Use an infrared lamp to warm the ambient temperature. Infrared lamps also work well for warming large work areas. Post Curing at 150°F for 2 hours will accelerate full curing. Rinse the Surface with warm water and mild detergent before use.

DEGLOSSING
Once the MAX CLR fully cures, deglossing the surface to create a satin finish can be easily done using an abrasive pad.
In this demonstration, a  SCOTCHBRITE  pad was used to de-gloss the surface.
Note the dramatic decrease in gloss after a light polishing with the abrasive pad.
Very-fine sandpaper (wet-sanding) also works well. HOT WATER IMMERSION TEST WOOD COATED MUG

Step Two: 

Choose The Best Epoxy Resin System For The Application
The epoxy resin used in fabricating a laminate will dictate how the FRP will perform when load or pressure is implied on the part.  To choose the proper resin system, consider the following factors that is crucial to a laminate's performance.
Size And Configuration Of The Part
(Number Of Plies  And Contoured, Flat Or Profiled)
Consolidating Force
(Free Standing Dry Or Hand Lay-up, Vacuum Bag Or Platen Press Curing)
Curing Capabilities
(Heat Cured Or Room Temperature Cured)
Mechanical Load Parameters
(Shearing Force, Torsional And Directional Load, Beam Strength)
Environmental Exposure
The Principal Role Of The Resin Is To Bind The Fabric Into A Homogeneous Rigid Substrate
(Operating Temperature, Ambient Conditions, Chemical Exposure, Cyclic Force Loading)
Material And Production Cost
(Buying In Bulk Will Always Provide The Best Overall Costs) These factors will dictate the design and the composition of the part and must be carefully considered during the design and engineering phase of the fabrication.

Step Three:

Proper Lay-Up Technique -Putting It All Together

Pre-lay-up notes

  • Lay out the fabric and pre-cut to size and set aside
  • Avoid distorting the weave pattern as much as possible
  • For fiberglass molding, ensure the mold is clean and adequate mold release is used
  • View our video presentation above "MAX EPOXY RESIN MIXING TECHNIQUE"
  • Mix the resin only when all needed materials and implements needed are ready and within reach

Mix the proper amount of resin needed and be accurate proportioning the resin and curing agent.  Adding more curing agent than the recommended mix ratio will not promote a faster cure. Over saturation or starving the fiberglass or any composite fabric will yield poor mechanical performance. When mechanical load or pressure is applied to the composite laminate, the physical strength of the fabric should bear the stress and not the resin. If the laminate is over saturated with the resin it will most likely to fracture or shatter instead of rebounding and resist damage.

Don’t how much resin to use to go with the fiberglass?

A good rule of thumb is to maintain a minimum of 30 to 35% resin content by weight. This is the optimum ratio used in high-performance prepreg (or pre-impregnated fabrics) typically used in aerospace and high-performance structural application. For general hand lay-ups, calculate using 60% fabric weight to 40% resin weight as a safety factor. This will ensure that the fabricated laminate will be below 40% resin content depending on the waste factor accrued during fabrication.

Place the entire pre-cut fiberglass to be used on a digital scale to determine the fabric to resin weight ratio. Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using OSY (ounces per square yard) or GSM ( grams per meter  square ) data.

THE USE OF A WEIGHING SCALE IS HIGHLY RECOMMENDED 

Purchase this scale with any of our product offering and the shipping cost of the scale is free.

Place the entire pre-cut fiberglass to be used on a digital scale to determine the fabric to resin weight ratio. Measuring by weight will ensure accurate composite fabrication and repeatability, rather than using OSY data.

Typical fabric weight regardless of weave pattern 1 ounce per square yard is equal to 28.35 grams 1 square yard equals to 1296 square inches (36 inches x 36 inches)

FOR EXAMPLE

1 yard of 8-ounces per square yard (OSY) fabric weighs 226 grams 1 yard of 10-ounces per square yard (OSY) fabric weighs 283 grams

Ounces per square yard or OSY is also known as aerial weight, which is the most common unit of measurement for composite fabrics. To determine how much resin is needed to adequately impregnate the fiberglass, use the following equation:

(Total Weight of Fabric divided by 60%)X( 40%)= weight of mixed resin needed

fw= fabric weigh rc= target resin content rn=resin needed MASTER EQUATION (fw/60%)x(40%)=rn

FOR EXAMPLE

1 Square Yard Of 8-ounce Per Square Yard (OSY) Fiberglass Fabric Weighs 226 Grams OSY Is The Common Term For The Fabric Density In The Composites Industry. (226 grams of dry fiberglass / 60%) X 40% =  150.66 grams of resin needed

So for every square yard of 8-ounce fabric, it will need 150.66 grams of mixed resin.

Computing For Resin And Curing Agent Amount  Needed For 150.66 Grams Of Mixed Resin

MIX RATIO OF RESIN SYSTEM IS 2:1 OR 50 PHR (per hundred resin)

2 = 66.67% (2/3) + 1 = 33.33%(1/3) (2+1)=3 or (66.67%+33.33%)=100% or (2/3+1/3)= 3/3

150.66 x 66.67%= 100.45 grams of Part A RESIN 150.66 x 33.33%= 50.21 grams of Part B CURING AGENT 100.45 + 50.21 = 150.66  A/B Resin Mixture

GENERAL LAY-UP PROCEDURE Apply the mixed resin onto the surface and then lay the fabric over the applied resin. Allow the resin to saturate through the fabric.

NOT THE OTHER WAY AROUND

This is one of the most common processing error that yields sub-standard laminates. By laying the fiberglass onto a layer of the prepared resin, less air bubbles are entrapped during the wetting-out stage. Air is pushed up and outwards instead of forcing the resin through the fabric which will entrap air bubbles. This technique will displace air pockets unhindered and uniformly disperse the impregnating resin throughout the fiberglass.

HAND LAY-UP TECHNIQUE

Minimize air entrapment or voids during the epoxy/fiberglass lay-up process to maximize the best strength performance. Air voids or porosity in a composite fiberglass structure is where failure originates when force is applied.

VACUUM BAGGING PROCESS  For performance critical application used in aerospace vehicles, composite framing for automotive vehicles and marine vessels, a process called 'Vacuum Bagging' is employed to ensure the complete consolidation of every layer of fabric. 
The entire tooling and lay-up are encased in an airtight envelope or bagging and a high-efficiency vacuum pump is used to draw out the air within the vacuum bag to create a negative atmospheric pressure. Once a full vacuum (29.9 Inches of Mercury) is achieved, the negative pressure applies a compacting force of 14.4 pounds per square inch (maximum vacuum pressure at sea level) is applied to the vacuum bag transferring the force to the entire surface area of the laminate.
Vacuum pressure is maintained until the resin cures to a solid. For room temperature curing resin system, the vacuum pump is left in operation for a minimum of 18 hours. External heat can be applied to the entire lay-up, thus accelerating the cure of the resin system.
The vacuum force also removes any entrapped air bubble between the layers of fabric and eliminate what is called, porosity or air voids. Porosity within a laminate creates weak spots in the structure that can be the source of mechanical failure when force or load is applied to the laminate.  
The standard atmosphere (symbol: atm) is a unit of pressure defined as 1
01325 Pa (1.01325 bar), equivalent to 
760 mm Mercury or 29.92 inches Mercury or
14.696 pounds per square inch of pressure.

AUTOCLAVE CURING PROCESS
 Autoclave curing processing is the most common method used in the large-scale production of composite products. The Aerospace Industry, which includes space exploration rockets and vehicles, deep space structures, and commercial and military airplane utilizes this composite fabrication process due to the critical nature of the application. The mechanical demands of the composite are often pushed to the upper limits and autoclaved process yields composites with the best weight to strength ratio.

BASIC OPERATION OF THE AUTOCLAVE PROCESS
In the autoclave process, high pressure and heat are applied to the part through the autoclave atmosphere, with a vacuum bag used to apply additional pressure and protect the laminate from the autoclave gases. 
The cure cycle for a specific application is usually determined empirically and, as a result, several cure cycles may be developed for a single material system, to account for differences in laminate thickness or to optimize particular properties in the cured part.
The typical autoclave cure cycle is a two-step process. First, vacuum and pressure are applied while the temperature is ramped up to an intermediate level and held there for a short period of time. The heat reduces the resin viscosity, allowing it to flow and making it easier for trapped air and volatiles to escape. The resin also begins wetting the fibers at this stage.
In the second ramp up, the temperature is raised to the final cure temperature and held for a sufficient length of time to complete the cure reaction. During this step, the viscosity continues to drop, but preset temperature ramp rates and hold times then stabilize viscosity at a level that permits adequate consolidation and fiber wetting, while avoiding excessive flow and subsequent resin starvation. 
These control factors also slow the reaction rate, which prevents excessive heat generation from the exothermic polymerization process . Upon completion, the cured mechanical performance of the composite is often much stronger and lighter compared to a hand lay-up, or vacuum bagged composite laminate.
VACUUM INFUSION PROCESS
Vacuum Infusion Process is also known in the composites industry as 
Vacuum Assisted Resin Transfer Molding or VARTM.

Similar to the Vacuum Bagging Process where the negative pressure is used to apply consolidation force to the laminate while the resin cures, the resin is infused into the fabric lay-up by sucking the impregnating resin and thus forming the composite laminate.

The VARTM Process produces parts that require less secondary steps, such as trimming, polishing or grinding with excellent mechanical properties. However, the vacuum infusion requires more additional or supplemental related equipment and expendable materials. So the pros and cons of each presented composite fabrication process should be carefully  determined  to suit the user's  capabilities  and needs.

Please view the following video demonstration of Vacuum Infusion or VARTM process.

Step Four: Proper Curing
Although we have formulated all of our MAX EPOXY RESIN SYSTEM product line to be resistant to amine-blush, it is recommended not to mix any resin systems in high humidity conditions, greater than 70% . Make sure that the substrate or material the epoxy resin system is being applied to is well prepared
 as possible to ensure the best-cured performance. 
Review the published data and information for proper usage, application, and general safety information. Our expert staff of engineers is always available for consultation and assistance.
Allow the lay-up to cure for a minimum of 24 to 36  hours before handling.
Optimum cured properties can take up to 7 days depending on the ambient cure condition. 
The ideal temperature cure condition of most room temperature epoxy resin is 22°C to 27°C at 20% relative humidity. Higher ambient curing temperatures will promote faster polymerization and development of cured mechanical properties.
IMPROVING MECHANICAL PERFORMANCE VIA POST HEAT CURE
 A short heat post cure will further improve the mechanical performance of most epoxy resins. Allow the applied resin system to cure at room temperature until for 18 to 24 hours and if possible, expose heat cure it in an oven or other sources of radiant heat (220°F to 250°F) for 45 minute to an hour. 
You can also expose it to direct sunlight but place a dark colored cover, such as a tarp or cardboard to protect it from ultraviolet exposure.
In general, room temperature cured epoxy resin has a maximum operating temperature of 160°F or lower.
A short heat post cure will ensure that the mixed epoxy system is fully cured, e specially for room temperature cure system that can take up to 7 days to achieve 100% cure.
Some darkening or yellowing of the epoxy resin may occur if overexposed to high temperature (>125°C).
AMINE BLUSH
The affinity of an amine compound (curing agent) to moisture and carbon dioxide creates a carbonate compound and forms what is called amine blush.
Amine blush is a wax-like layer that forms as most epoxies cure. If the epoxy system is cured in extreme humidity (>70%).
It will be seen as a white and waxy layer that must be removed by physical sanding of the surface followed by an acetone wipe.

Latent epoxy resins are systems that are mixed together at room temperature and will begin polymerization but it will not achieve full cure unless it is exposed to a heat cure cycle. In general, these are high-performance systems that demonstrate exceptional performance under extreme conditions such as high mechanical performance under heat and cryogenic temperatures, chemical resistance or any environment that epoxy room temperature system perform marginally or poorly.
  Upon the mixing of the resin and curing agent polymerization will begin and will only achieve a partial cure. Some resins may appear cured or dry to the touch,  this state is called 'B-Stage Cure', but upon application of force will either be gummy or brittle almost glass-like and will dissolve in most solvents. The semi-cured resin must be exposed to an elevated temperature for it to continue polymerization and achieve full cure. 
HEAT ACTIVATED CURING SYSTEMS
This type of epoxy system will not polymerize unless it is exposed to the activation temperature of the curing agent which can be as low as 100 °C  and as high as 250°C

Storage

Secure the caps for both bottles after use and store above 65°F minimum temperature to prevent re-crystallization. 
The resin system will remain viable for at least 12 months or longer when stored properly.
The PART A or resin component may 'crystallize' after prolonged storage. 
Please inspect the PART A bottle for any solid crystallization that will appear on the bottom of the bottle.

 Proportioning the correct amount is equally as important to attain the intended cured properties of the resin system. The container in which the epoxy and curing agent is mixed is an important consideration when mixing an epoxy resin system. The container must withstand the tenacity of the chemical and must be free of contamination. Most epoxy curing agent has a degree of corrosivity, as a general practice, protective gloves should be worn when handling chemicals of the same nature.
