Differential Working Time Comparison
THIS GRAPH DEMONSTRATES THE REACTION RATE OF THE 3 DIFFERENT VERSIONS BY MEASURING THE EXOTHERMIC HEAT ENERGY.
On a 150 gram mass mixture, MAX CLR FAST A/B exhibits similar working time of up to 20 minutes compared to the other MAX CLR versions.
Note the faster increase in temperature rise.
Based on the result very above, very little time was lost in working time but gained significant acceleration in cure time.
The 150 grams sample quickly gelled after 25 minutes and was tack free after 5 minutes gel.
The other two versions took another 20 minutes and gradually solidified into a tack free surface.
The shorter working time of the MAX CLR FAST A/B allows faster processing without sacrificing color stability and excessive brittleness.
ALTHOUGH THE MAX CLR FAST DEMONSTRATED A FASTER SET-UP OR HANDLING TIME,
ALLOW THE APPLICATION TO CURE FOR AT LEAST A MINIMUM OF 3 TO 7 DAYS TO ACHIEVE THE MAXIMUM CURED PERFORMANCE.
The higher peak exotherm may exclude MAX CLR FAST A/B to be used in large casting applications

WHICH EPOXY IS BEST FOR YOUR APPLICATION?
Epoxy based polymers are one of the most versatile resins that can be modified into a multitude of applications and fit very specific application and use. It offers ease of use and are generally much safer to handle than polyester and polyurethane based resin system.
To answer this question, one must determine the load or type of stress that
the resin must endure during the life of the fabricated part.
Through analysis of its resistance and conclusively, its ultimate mechanical performance at the point of destruction, one can determine and establish designs parameters that involves the epoxy resin as an integral part of the composite part.
Why is Impact Testing Important?
The impact resistance of a fabricated part is one of the most important properties of composite's ultimate performance.
It will establish the limits of nominal operation and reveal the maximum amount of energy via rapid impact that it can withstand in a singular and repeated impact events.
Other important mechanical aspect such as work energy load, maximum energy load and a stress/strain limitations can be determined by impact testing.

Composite Fabricating Basics
Step One: Choose the best fabric to use for the application.
Plain weave In this most simple weave pattern, warp and fill yarns are interlaced over and under each other in alternating fashion. The plain weave provides good stability, porosity and the least yarn slippage for a given yarn count.
Mock Leno The mock leno weave is used where relatively low numbers of yarns are involved. The leno weave locks the yarns in place by crossing two or more warp threads over each other and interlacing with one or more filling threads.
Four Harness Satin (Crowfoot) The 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.
Eight Harness Satin The 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.
Twill weave This twill weave is more pliable than the plain weave and has better drapability 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.
Chrome Finishes (Volan A) F-16 & F-3
Heat cleaned fabric is saturated in a methacrylate chromic chloride solution, cured, and washed to remove any soluble salts.
Both F-16 and F-3 are Volan type finishes with F-3 being a highest chrome content version.
Used with polyesters, phenolics, and epoxies, F-16 and F-3 fabrics yields a light green laminant
Please visit our ebay store for all available composite fabric that will suit your need.
Step Two: Choose the best epoxy resin system for the job
The principal role of the resin is to bind the fabric into a unitize homogenous rigid substrate called a composite laminate or FRP- FIBER REINFORCED PLASTIC.The epoxy resin used in fabricating a laminate will dictate how the FRP will perform when load or pressure is implied on the part.
Step Three: Proper Fiberglass, Carbon Fiber, Kevlar And Other Composite Fabric Lay-Up Technique
Pre-lay-up notes
Lay out the fabric and precut to size and set aside
Avoid distorting the weave pattern as much as possible
For fiberglass molding, insure 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.
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, use 60% fabric weight to 40% resin weight as a safe factor.
Place the entire precut fiberglass to be used on a scale and determine the weight.
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 know as aerial weight which is the most common unit of measurement for composite fabrics.
If a scale is available, measuring by weight will insure better composite
fabrication and repeatability, rather than using OSY data.
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 weight
rc = target resin content
rn= resin needed
(fw/60%)x(.40%)= rn
(224 grams of dry fiberglass / 60%) X 40% = 149.3 grams of resin needed
So for every square yard of 8 ounce fabric, you will need 4.50 fluid ounces of mixed resin.
Common Factors Of 100% Solids (Zero volatiles and unfilled epoxy resin)
1 gallon of resin = 4239 grams (1.12 g/cc)
1 gallon = 128 fluid ounces
1 fluid ounce of resin = 33.17 grams
Apply the mixed resin unto the surface and then lay the fabric and allow the resin to saturate 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 unto a film of 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 unhindered and uniformly disperse through out the fiberglass with minimal mechanical agitation or spreading.
Given enough time and the proper selection of the fabric's surface treatment, most dry fabric will equalize the distribution of the applied resin naturally thus creating less air bubbles to be entrapped within the laminant. It is then very important that the proper viscosity, working time and surface treatment of the fabric must considered. There are also fabricating techniques that can be employed to reduce air entrapment within the laminant matrix. Depending on the size of the part, processes such as high pressure pressing, vacuum bagging or autoclaving are superior methods over hand lay-ups.
Air voids or porosity within the laminate is typically where failure propagates when load is applied.

So for every square yard of 8 ounce fabric, you will need 4.50 fluid ounces of mixed resin.
Step Four: Proper Curing
Proper and thorough mixing of the epoxy resin and curing agent and with equal importance is to achieve 100% polymerization . Most binary or 2 part epoxy resins system undergoes 3 distinct stages to achieve full cure.
Allow to cure for 24 hours before handling. Optimum cured properties can take up to 7 days depending on the ambient cure condition.
The ideal 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 less cure time.
Improving mechanical performance via post heat cure
A short heat post cure will further improve the mechanical performance of most epoxy resins. In general room temperature cured epoxy resin has a maximum operating temperature of 250°F and 160°F under stress or load.
Some darkening or yellowing of the epoxy resin may occur when over exposed to high temperature (>250 F).
MAX CLR FAST is resistant to amine blush, but curing any epoxy resin at high humidity will create a level of amine blush.
Do not mix the resin when the ambient humidity is above 60%.
AMINE BLUSH
The affinity of an amine compound (curing agent) to moisture and carbon dioxide
creates 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.
Amine blush is due to moisture as well as the amount of carbon dioxide
present during the curing process.
Most heat cured resin will fall into two catagories of heat curing.
