Use these Yorker caps to dispense the material with ease and minimize over pouring and reduce spills. We do not recommend usingdispensing pumps. The curing agent or part B of any epoxy resin system is sensitive to moisture and carbon dioxide, which will react with the curing agent and form carbamate crystals (salt-like crystals that form on the tip of the pump) and reduce reactivity. CARBAMATE CRYSTALS THAT FORM ON THE PUMP WHEN THE CURING AGENT IS EXPOSED AMBIENT MOISTURE AND CARBON DIOXIDE. THESE CRYSTALS ARE INSOLUBLE IN EPOXY RESIN RESULTING IN CONTAMINATION AND CAUSES POOR CURE AND AMINE-BLUSHING. Use these Yorker caps and cut the tip to meter the orifice of the of the tip for accurate dispensing. When done, just replace the tip cap and it will exclude ambient moisture and air and keep the resin system viable for years.

Governed by the many laws and dynamics of physics, a skilled chemist or materials engineer can determine the design equilibrium and ultimate performance by careful analysis of the material’s disassociation and the manner of its destruction.With this knowledge, other aspects of mechanical performance can be accurately derived and through skillful engineering, one can determine:The impact energies the part can be expected to see in its lifetimeThe type of impact that will deliver that energy, and thenA material that will resist such assaults over the projected lifespan.MAX CLR IMPACT RESISTANCE TEST - YouTubeVideo will open in a new window USE THESE THEORETICAL FACTORS THAT RELATES TO ANY UNDILUTED EPOXY RESIN AS A GUIDE: 1 GALLON = 231 CUBIC INCHES1 GALLON OF RESIN CAN COVERS 1608 SQUARE FEET1 MIL OR 0.001 INCH CURED COATING THICKNESS1 GALLON OF RESIN IS 128 OUNCES1 GALLON OF MIXED EPOXY RESIN IS 9.23 POUNDS1 GALLON OF RESIN IS 3.7854 LITERSDuring colder seasons, the epoxy resin and curing agent will be thicker or higher in viscosity. Temper both components to at least 23°c to 25°c before mixing. A good method is to place the bottles in a warm room for 24 hours or place both components in a plastic bag and seal tightly and then place in hot water bath for about 2 to 4 hours. Remove from the water bath and ensure that the components are below 80°f before mixing together. This will lower the viscosity to the consistency as shown in the video demonstration.

This will create a low viscosity penetrating sealant to lock in any grain raising. Allow curing overnight.Upon cure, lightly sand the surface to remove any raised wood grain, sand off just enough to remove any gloss and then clean with a tack rag.Repeat if necessary until a smooth surface is achieved. If embedding pictures or other items onto the tabletop, plaques or decoupage projects, secure the items using the MAX CLR-HP as an adhesive and allow to set-up before coating.Pour the mixed MAX CLR HP into another container and mix for another minute (this ensures that no tacky spots caused by unmixed material will be applied) and pour or brush or foam roller (use foam roller for a lint-free application) coat apply onto the substrate to be sealed.Allow the coating to flow out evenly and protect the surface from airborne dust and debris until it has set-up. If a thicker coating is desired, allow to set-up for at least 6 hours before applying subsequent coats. To remove stubborn surface bubbles, pass a flame from a propane torch over the surface very, very quickly and the air bubbles will pop. Allow the completed coating to cure for at least 24 hours before handling.Optional step for a super high gloss finish.Upon full cure of the coating, lightly wet sand the surface using an 1800-grit, then a 2000 grit or finer polishing or rubbing compound and apply durable car polish.MAX CLR HP TABLE TOP MOVIE Video will open in a new windowTo Use MAX CLR-HP A/B As A Casting ResinClean the mold and apply a good quality release agent such as wax mold release or PVA mold release.Slowly pour the mixed MAX CLR HP into the on the corner of the mold cavity and allow the resin to fill the cavity allowing the entrapped air bubbles to rise to the surface.Remove any surface air bubbles using the torch technique described above.Allow to cure at room temperature for 24 to 36 hours.To use MAX CLR-HP A/B As An Electrical Potting CompoundPlace the circuit board in the casing or cavity and secure all wiring leads to its desired position.Pour the mixed MAX CLR-HP into one corner of the cavity and fill to the desired level.

This method is also defined as SYNERGISTIC COMPOSITION. COMPOSITE MATERIAL COMPOSITIONREINFORCING FABRIC & IMPREGNATING RESIN PLUS 'ENGINEERED PROCESS' EQUALS COMPOSITE LAMINATE WITH THE BEST WEIGHT TO STRENGTH PERFORMANCE With respect to the raw materials selection -fabric and resin, the fabricating process and the and curing and test validation of composite part, these aspects must be carefully considered and in the engineering phase of the composite. Step One: Fabric SelectionTYPES OF FABRIC WEAVE STYLE AND SURFACE FINISHINGFOR RESIN TYPE COMPATIBILITY Fabrics are generally considered ”balanced” if the breaking strength is within 15% warp to fill and are best in bias applications on lightweight structures. “Unbalanced” fabrics are excellent when a greater load is required one direction and a lesser load in the perpendicular direction. Tow: The bundle of individual carbon filaments used to weave carbon fabric. 50k tow means there are 48-50,000 carbon filaments in the tow. Smaller tow i.e. 12k, 6k, 3k and 1k are obtained by dividing the 50k tow into smaller bundles.Thread Count: The number of threads (tow in carbon and yarn in Aramid) per inch. The first number will be the warp count and the second will be the fill count. Fill: The threads that run the width of the roll or bolt and perpendicular to the warp threads. Warp: The threads that run the length of the roll or bolt and perpendicular to the fill threads. Finish: The chemical treatment to fiberglass making it compatible with resin systems, therefore improving the bond between the fiber and the resin. Finishing fiberglass typically decreases the fiber strength by as much as 50%. Both Silane and Volan finishes are epoxy compatible. Historically, Volan has been considered a softer finish for a more pliable fabric, but recent advances have yielded some excellent soft Silane finishes.Thickness: Measured in fractions of an inch. The thicker the fabric the more resin required to fill the weave to obtain a surface-smooth finished part.Weaves:Plain weave means the warp and fill threads cross alternately. This is the most common weave.4 Harness (4 HS Satin or crowfoot) weave means the fill thread floats over three warp threads, then under one warp thread. This weave is more pliable than the plain weave, therefore conforms to complex curves more easily.8 Harness (8 HS Satin) weave means the fill thread floats over seven warp threads, then under one warp thread. This weave is the most pliable of the standard fiberglass weaves.2 x 2 Twill weave means the fill thread floats over two warp threads, then fewer than two warp threads. This weave is found most commonly in carbon fabrics and is more pliable than plain weave.Most fabrics are stronger in the warp than the fill because higher tension is placed on the warp fiber keeping it straighter during the weaving process. Rare exceptions occur when a larger, therefore stronger thread is used in the fill direction than the warp direction. PLAIN WEAVEIs a very simple weave pattern and the most common style. The warp and fill yarns are interlaced over and under each other in alternating fashion. Plain weave provides good stability, porosity and the least yarn slippage for a given yarn count. 8 HARNESS SATIN WEAVEThe eight-harness satin is similar to the four-harness satin except that one filling yarn floats over seven warp yarns and under one.This is a very pliable weave and is used for forming over curved surfaces. 4 HARNESS SATIN WEAVEThe four-harness satin weave is more pliable than the plain weave and is easier to conform to curved surfaces typical in reinforced plastics. In this weave pattern, there is a three by one interfacing where a filling yarn floats over three warp yarns and under one. 2x2 TWILL WEAVETwill weave is more pliable than the plain weave and has better drivability while maintaining more fabric stability than a four or eight harness satin weave. The weave pattern is characterized by a diagonal rib created by one warp yarn floating over at least two filling yarns. SATIN WEAVE TYPE CONFORMITY UNTO CURVED SHAPES Plain Weaves, Bi-axial, Unidirectional Styles For Directional High Strength Parts Use this weave style cloth when high strength parts are desired.It is ideal for reinforcement, mold making, aircraft and auto parts tooling, marine and other composite lightweight applications.7544 Fiberglass - YouTube FIBERGLASS FINISHING FOR RESIN COMPATIBILITYAll of the fiberglass fabrics is woven By HEXCEL COMPOSITES, a leading manufacturer of composite materials engineered for high-performance applications in marine, aerospace for commercial and military, automotive, sporting goods and other application-critical performance.

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 data.THE USE OF A WEIGHING SCALE IS HIGHLY RECOMMENDED Purchase this scale with any of product offering and the shipping cost of the scale is free. Please request a total before paying for combined shipping savings. https://www.ebay.com/itm/222630300203Typical fabric weight regardless of weave pattern1 ounce per square yard is equal to 28.35 grams1 square yard equals to 1296 square inches (36 inches x 36 inches)FOR EXAMPLE1 yard of 8-ounces per square yard (OSY) fabric weighs 226 grams1 yard of 10-ounces per square yard (OSY) fabric weighs 283 gramsOunces 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 neededORfw= fabric weightrc= target resin contentrn=resin neededMASTER EQUATION(fw/60%)x(40%)=rnFOR EXAMPLE1 SQUARE YARD OF 8-OSY FIBERGLASS FABRIC WEIGHS 226 GRAMS(226 grams of dry fiberglass / 60%) X 40% = 150.66 grams of resin neededSo for every square yard of 8-ounce fabric, it will need 150.66 grams of mixed resin.Computing For Resin And Curing Agent Amount150.66 grams of resin neededMIX RATIO OF RESIN SYSTEM IS 2:1 OR50 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)= 3/3150.66 x 66.67%= 100.45 grams of Part A RESIN150.66 x 33.33%= 50.21 grams of Part B CURING AGENT100.45 + 50.21 = 150.66 A/B MIXTUREGENERAL LAY-UP PROCEDUREApply the mixed resin onto the surface and then lay the fabric and allow the resin to saturate through the fabric.NOT THE OTHER WAY AROUNDThis is one of the most common processing error that yields sub-standard laminates. By laying the fiberglass onto a layer of the prepared resin, fewer 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 Eliminating air entrapment or void porosity in an epoxy/fiberglass lay-up processFiberglass Hand Lay Up For Canoe and Kayak Building- Cedar Strip Kayak Fiberglassing - YouTubeVideo will open in a new windowBasic Hand Lay-up FiberglassingVideo will open in a new windowVACUUM 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 101325 Pa (1.01325 bar), equivalent to 760 mm Mercury or 29.92 inches Mercury or14.696 pounds per square inch of pressure.FiberglaSs And Carbon Fiber Vacuum Bagging and Flat Panel Laminate - YouTubeVideo will open in a new window AUTOCLAVE CURING PROCESS Autoclave curing processing is the most common method used in 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 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 PROCESSVacuum 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 which explains the process of Vacuum Infusion or VARTM process.MAX 1618 A/B VACUUM ASSISTED RESIN TRANSFER MOLDING PROCESSCARBON FIBER VACUUM INFUSION WITH EPOXY RESIN - VACUUM BAGGING WITH MAX 1618 EPOXY RESIN - YouTubeVideo will open in a new windowStep Four: Proper CuringAlthough we have formulated all of ur 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 60%.Always 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. Always review the published data and information for proper usage, application, and general safety information. Our expert staff of engineers are 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 to 27 degrees Celsius at 20% relative humidity.Higher ambient curing temperatures will promote faster polymerization and development of cured mechanical properties.IMPROVING MECHANICAL PERFORMANCE BY HEAT POST CURING 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) for45 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, especially 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 (>250 F). AMINE BLUSHThe 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. OTHER TYPES OF EPOXY RESIN CURE MECHANISMLATENT CURING SYSTEMSLatent 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 SYSTEMSThis 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 200F and as high as 400F. In most instances, our MAX EPOXY SYSTEMS epoxy system can be stored at room temperature and remain liquid for up to six months and longer.

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.
