Use
epoxy resins: Synthetic resins producedby copolymerizing epoxidecompounds with phenols. They contain-O- linkages and epoxide groupsand are usually viscous liquids. Theycan be hardened by addition ofagents, such as polyamines, thatform cross-linkages. Alternatively,catalysts may be used to induce furtherpolymerization of the resin.Epoxy resins are used in electricalequipment and in the chemical industry(because of resistance tochemical attack). They are also usedas adhesives.
