摘要:
The present invention provides mononuclear aromatic diglycidyl ether epoxy resins, such as alkyl resorcinols and alkyl hydroquinones, having one or two alkyl containing, cycloalkyi containing, alkoxy containing, alkylsulfide containing, alkylsilyl containing or alkylether containing groups, two alkylamino containing groups, one N- heterocycloalkyl group, and mixtures thereof, as well as two component liquid coating compositions comprising as an epoxy component the epoxy resins, and, as a second component, a hardener. Coating compositions of the present invention provide low viscosity coating compositions even at 100% solids and enable the use of epoxy coating compositions in remote field applications.
