FRP Epoxy Adhesive

Two component epoxies feature unique versatility in application and performance. These systems consist of a resin and a hardener that can be formulated to offer a wide range of mechanical, thermal, optical and electrical properties. While mix ratios differ, they all offer the ability to cure at ambient temperatures or at elevated temperatures for faster cures.

The chemical resistance of epoxies is excellent against basic solutions (best choice for brine tanks). Epoxies are more expensive than polyesters, and cure times are longer, but their extended range of properties can make them the cost/performance choice for critical applications. The epoxy resins are formed by a reaction of an epoxide (like epichlorohydrin) with a hardener or polyamine (like triethylenetetramine) that has tremendous cross-linking to create a very tough and yet stiff polymer. The viscosity of epoxies is another step higher than polyesters or vinyl esters.  Most epoxies start in the range of 900 centipoise. Attributes of epoxy resins include extremely low shrinkage, good dimensional stability, high temperature resistance, good fatigue and adherence to reinforcements. Given the extensive double bonding of the resin, normal shrinkage is less than might be expected based on its strength.
