REACTION RATE OF MAX CLR EPOXY RESIN SERIES
The working time of an epoxy system is determined by the time it takes for a given volume or mass of mixed resin to convert from a liquid to a solid or cured plastic polymer. By measuring the exothermic temperature or the heat energy produced during its reaction, the amount of time in which the mixed resin should be applied and used to provide the optimal performance.
This exothermic heat is apparent when the mixed resin is allowed to react in a confined mass, which could reach in excess of 300 F.
The reaction rate will be much slower if the same mass of resin is spread over a larger area.
This time scale is called THIN FILM SET TIME that is the time where the surface of the polymer becomes tack free.
Note that all three versions of the MAX CLR demonstrate almost identical exothermic temperature until 20 minutes from the initial mix time.
The MAX CLR FAST begins to accelerate and produce higher exothermic temperature after 20 minutes; its reaction rate increases exponentially as the heat energy it generates produces a catalytic acceleration of cure.
MAX BOND A/B STRUCTURAL RESIN SYSTEM
Formulated as a structural adhesive with a none-flowing consistency. Excellent for vertical, overhead bonding or creating fillet bonding, cylinders or corner joints. It can be applied on vertical or overhead applications.

Step One: Choose the best fabric to use for the application
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.
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.
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.
The eight harness satin is similar to the four harness satin except that one filling yarn floats over seven warp yarns and under one.
The twill weave style is more pliable than the plain weave and drapes with less resistance 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.
for contoured parts fabrication
This style fabric is one of the easiest fabrics to use and it is ideal for laying up cowls, fuselages, ducts and other contoured surfaces with minimal distortions. The fabric is more pliable and can comply with complex contours and spherical shapes. Because of the finer weave it, several layers of the satin weave fabric is typically used as the surface ply or the fascia in conjunction with heavier and courser weaves.
This technique helps reduce fabric weave print through and requires less gel coat and creates a smoother surface.
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.
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.
For bulk reinforcing or structural applications and high strength panel and deliberate linear angel part fabrication
Use this fiberglass cloth when high strength parts are desired. It is ideal for construction, composites reinforcement, mold making, aircraft and auto parts tooling, marine and other composite lightweight applications.
A unidirectional fabric is constructed were the all the roving or fabric strand is oriented in one direction. This provides high strength in a known directional angle. The Design of must be carefully considered and insure that the resistive force is well identified and incorporated in the luminant s design.
Unidirectional laminate offers outstanding strength-to-weight ratio, Fiber to resin ratio control and stability (minimized probability of resin-rich and/or resin-dry areas), exceptionally directional high impact resistance. The integrity is maintained through very fine, adhesive coated fill yarns that are bonded to but not interwoven.
Equally as important in choosing a fabric weave style is the fabric finishing
Fabric finishing is another important aspect that must be considered when choosing any type of composite fabric.
The finishing of the fabric will dictate the compatibility (WET-OUT) of the epoxy resin with the fabric and how well these two factors will form a homogenous substrate.
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, phenolic, and epoxies, F-16 and F-3 fabrics yields a light green laminate
The principal role of an epoxy resin is to bind the fabric into a unitize and homogenous rigid substrate called a composite laminant or FRP- FIBER REINFORCED PLASTIC.
The epoxy resin used in fabricating a laminant will dictate how the FRP will perform when load or pressure is applied on the part.
Step Three: Proper Fiberglass, Carbon Fiber, Kevlar And Other Composite Fabric Lay-Up Technique
Over saturation or starving the fiberglass or any composite lay-up will yield poor mechanical performance.
(Total Weight of Fabric divided by 60%) X(40%)= weight of mixed resin needed
So for every square yard of 8 ounce fabric, you will need 4.50 fluid ounces of mixed resin.
Apply the mixed resin unto the surface and then lay the fabric and allow the resin to saturate the fabric.
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 finishing 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 the fabric density and weave style must be determined to yield the best result.
Air voids or porosity within the laminate is typically where failure propagates when load is applied.

Step Four: Proper CuringRoom Temperature Cured Epoxy Resins
An epoxy system blush or "amine blush" is a waxy layer that forms as most epoxies cure. When the epoxy is cured in extreme humidity, it will be seen as a white and waxy layer, that must be removed by physical sanding of the surface followed aby an acetone wipe. Amine blush is due to moisture as well as the amount of carbon dioxide present during the curing process. The affinity of an amine (curing agent) to moisture and carbon dioxide creates carbonate compounds.Typically a short heat post cure will further improve the mechanical performance of most epoxy resins. In general room temperature cured epoxy resin have a maximum operating temperature of 250F. Some darkening or yellowing of the epoxy resin may occur when heat cured.
IMPROVING MECHANICAL PERFORMANCE BY HEAT POST CURING
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).
