Abstract
A diglycidyl ether of a diphenol, such as a diglycidyl ether of bisphenol A, is reacted with bisphenol S to form a chain-extended epoxy resin. This chain-extended epoxy resin is then esterified with a fatty acid derived from a drying oil, such as linseed oil fatty acid. The resulting epoxy resin ester is cut with a solvent for use as a rapid drying coating material. A primer using this material is also disclosed.
