Abstract: The present disclosure relates to a B-stageable adhesive composition and a coating prepared by the same. In the present disclosure, the adhesive composition comprises the following components in solid content percentage: (A) 15% to 50% by weight of a first epoxy resin with a weight average molecular weight Mw of 8,000 g/mol or more; (B) 3% to 15% by weight of a second epoxy resin with a weight average molecular weight Mw of 200 to 2,000 g/mol; (C) 20% to 50% by weight of a carboxyl terminated polyester or derivates thereof; (D) 0.1% to 2.5% by weight of a first curing agent capable of reacting with epoxy group; (E) 0.1% to 2.5% by weight of a second curing agent capable of reacting with carboxyl group; and (F) 0% to 40% by weight of a flame retardant. The coating obtained from the adhesive composition of the present disclosure shows good adhesion strength, heat resistance and functional properties such as flame retardance and prolonged shelf life.
