摘要:
High solids coating compositions comprising a polycaprolactone derivative and a mixture of a methylolated melamine and a low molecular weight polyol; and, optionally, solvent and catalyst. The polycaprolactone derivative used in the coating compositions is the reaction product of a polycaprolactone polyol, a polyisocyanate and an anhydride of a polycarboxylic acid; the polycaprolactone polyol has an average of at least two hydroxyl groups in the molecule, a hydroxyl number of from about 15 to about 600 and an average molecular weight of from about 290 to about 6,000. The carboxylic acid anhydride mentioned has at least one intramolecular carboxylic anhydride group. The polycaprolactone derivatives are water insoluble.
