The invention provides the following resin compositions. 1. A composition comprising (A), (B), (C) and (D); 2. a composition comprising (A), (E) and (D); 3. a composition comprising (F), (G) and (D); and 4. a composition comprising (H), (C) and (D). where (A) a high molecular weigh, hydroxy compound containing an average of 2 or more hydroxyl groups per molecule and having a number average molecular weight of 3,000 to 200,000; (B) an epoxy compound containing an average of 2 or more epoxy groups per molecule and having a number average molecular weight of 120 to 200,000, (C) a silane compound containing an average of 1 or more alkoxysilane, silanol and/or acyloxysilane groups per molecule and having a number average molecular weight of 104 to 200,000, (D) at least one chelate compound of aluminum, titanium or zirconium, (E) a high molecular weight compound containing an average of 2 or more epoxy groups and an average of 1 or more alkoxysilane, silanol and/or acyloxysilane groups per molecule and having a number average molecular weight of 3,000 to 200,000, (F) a high molecular weight compound containing an average of 2 or more hydroxyl groups and an average of 1 or more alkoxysilane, silanol and/or acyloxysilane groups per molecule and having a number average molecular weight of 3,000 to 200,000; (G) a low molecular weight compound containing an average of 2 or more epoxy groups per molecule and having a number average molecular weight of 240 to 5,000; and (H) a high molecular weight compound containing an average of 2 or more hydroxyl groups and an average of 2 or more epoxy groups per molecule and having a number average molecular weight of 3,000 to 200,000. A method of curing these compositions at a temperature not exceeding 100°C is also described.
