Phenolic epoxy resin is a kind of phenolic resins modified at the phenolic hydroxyl group to include an epoxide functional group (usually a –CH2-(C2H3O) group, where -(C2H3O) is the three-membered epoxide ring). The added functionality of the phenolic resin increases the ability for the resin to crosslink, creating a stronger polymer with high resistivities.

Molding compounds; surface coatings; adhesives; laminating or reinforcing plastics

Phenolic epoxy resin is often used as coatings or resistive top coats for drums, pipes, floors, tanks and automotive parts. The high chemical and solvent resistivities and temperature compatibility of it is most useful in high-performance applications and corrosion resistance.

The toxicity of epoxy resin systems results from the toxicity of the various components, each of which must be considered.
