Applicable Base Polymer Properties

Because of their thermosetting molecular structure, epoxy adhesives exhibit excellent tensile-shear strength but poor peel strength unless modified with a more resilient polymer. Epoxy adhesives offer excellent resistance to oil, moisture, and many solvents. Low shrinkage on curing and high resistance to creep under prolonged stress are characteristics of many high quality epoxy adhesives. Epoxy resins have no evolution of volatiles during cure and are useful in gap-filling applications.

Resulting Properties

Epikure 3300 is a very low viscosity, light colored cycloaliphatic amine curing agent for use in formulating heat cured epoxies. As a sole curing agent, EPIKURE Curing Agent 3300 can yield epoxy systems with relatively high heat distortion properties when properly cured. The formulation above shows a rigid epoxy resin formulation that can be used as either a binder or casting compound. The formulation is also often used in the electrical / electronic industry where good electrical insulation characteristics are required.
