Epoxy resin adhesive is a reprocessing or modification of epoxy resin to make its performance parameters meet specific requirements. Usually epoxy resin adhesives are also used with curing agents and need to be mixed well to be fully cured. Generally, the epoxy resin adhesive is called A adhesive or main agent, and the curing agent is called B adhesive or curing agent(hardener).

Main properties of epoxy resin adhesives before curing

Colur, viscosity, specific gravity, proportioning, gel time, open time, curing time, thixotropy (flow stopping), hardness, surface tension, etc.

Main properties of epoxy resin adhesive after curing

Resistivity, proof voltage, water absorption, compressive strength, tensile strength, shear strength, peel strength, impact strength, heat deflection temperature under load, glass transition temperature, internal stress, chemical resistance, elongation, shrinkage coefficient, thermal conductivity, electrical conductivity, weathering resistance, aging resistance, dielectric constant.

Curing characteristics of epoxy resin adhesive

• Most of the epoxy resin adhesives are heat-setting adhesives.

• The higher the temperature of the epoxy resin adhesive, the faster the curing.

• The more the amount mixed at one time, the faster the curing.

• The curing process has exothermic phenomenon, etc.
