Epoxy based polymers are one of the most versatile thermoset resins that can be modified into a multitude of applications and fit very specific task as demanded by the application. It offers ease of use and generally safer to handle over other types of thermoset resins which makes it the choice material for many high performance composites. IMPACT RESISTANCE OF MAX CLR-HP A/B
Impact testing is one of the most revealing test methods that demonstrate a material's ability to resist and withstand a high-rate of pressure loading, its behavior during and after the impact can define its maximum mechanical property and conditional limits upon its destruction. Why is Impact Testing Important? The impact resistance of an object provides the ultimate measure of its resistance to its definitive destruction. 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 lifetime, -The type of impact that will deliver that energy, and then - A material that will resist such assaults over the projected life span.

DURING 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 FORM THE WATER BATH AND INSURE THAT THE COMPONENTS ARE BELOW 80°F BEFORE MIXING TOGETHER. THIS WILL LOWER THE VISCOSITY TO THE CONSISTENCY AS SHOWN ON THE VIDEO DEMONSTRATION. PLEASE VIEW THE FOLLOWING VIDEO FOR THE PROPER MIXING OF EPOXY RESIN. IT DEMONSTRATES THE PROPER TECHNIQUE OF MIXING ANY TYPE OF EPOXY RESIN REGARDLESS OF MIX RATIO OR FORMULATION.

If coating a wood substrate as a base, pre seal the wood with MAX CLR HP thinned down with 10% to 20% acetone or MEK by volume. This will create a low viscosity penetrating sealant to lock in any grain raising. Allow to cure 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 unto the tabletop, plaques or a 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 insures 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 unto 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 a 1800 grit then an a 2000 grit or finer polishing or rubbing compound and apply durable car polish.
To Use MAX CLR-HP A/B As A Casting Resin Clean 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 corner of 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 Compound Place 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. By pouring or filling the resin from corner of the electronic casing any air voids is pushed away and reduce the possibility of "high-pots" that is caused by voids in the potting compound. Cure at room temperature for at least 24 hours before putting in service. Thick Casting Applications Mix and pour about 200 grams of Part A resin to 100 grams Curing agent per stage casting until the desired thickness is achieved. Allow 90 minutes in between staged casting or until the prior pour has cooled before pouring the next volume. No sanding is needed in between cast and allow to cure for at least 36 hours before demolding.

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. OUR GENERAL EPOXY RESIN SYSTEM SELECTION FORMULATED FOR SPECIFIC APPLICATIONS Step Three: Proper Lay-Up Technique Pre-lay-up notes Lay out the fabric and pre-cut to size and set aside
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 data.
Typical fabric weights regardless of weave pattern 1 yard of 8 OSY fabric at 38 inches wide weighs 224 grams 1 yard of 10 OSY fabric at 38 inches wide weighs 280 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 OR fw= fabric weight rc= target resin content rn=resin needed MASTER EQUATION (fw/60%)x(40%)=rn FOR EXAMPLE 1 SQUARE YARD OF 8-OSY FIBERGLASS FABRIC WEIGHS 224 GRAMS (224 grams of dry fiberglass / 60%) X 40% = 149.33 grams of resin needed So for every square yard of 8-ounce fabric, It will need 149.33 grams of mixed resin. Computing for resin and curing agent requirements based on 149.33 grams of resin needed 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)= 3/3 149.33x 66.67%= 99.56 grams of Part A RESIN 149.33x 33.33%= 49.77 grams of Part B Curing Agent 99.56+ 49.77 = 149.33 A/B MIXTURE Apply the mixed resin onto the surface and then lay the fabric and 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 film of 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 dispersed throughout the fiberglass with minimal mechanical agitation or by spreading.
DETERMINATION OF FIBER TO RESIN RATIO For Vacuum Bagging And Resin Infussion Process
Similar to "addition cure" or catalytic polymerization, Ultraviolet Curing is another method that has gained popular use in the polymer adhesives and coatings application. It offers a unique curing mechanism that converts a liquid polymer into a solid plastic upon exposure to UV radiation. The two common commercially significant method are "FREE RADICAL INITIATION" and CATIONIC REACTION. In both reaction polymerization occurs via decomposition of a Photoinitiator blended within the resin system; upon exposure to the adequate wavelength of Ultraviolet energy the photoinitiator degrades and cause a ring opening or cleavage of the photoinitiator molecule and induces rapid polymerization or cross-linking. The polymerization reaction can be either free radical or cationic and occurs almost instantaneous creation of a polymer network. POSSIBLE HEAT CURING TECHNIQUES NEED MORE INFORMATION?
