Abstract
PURPOSE: To prepare an unsaturated epoxyester resin composition having low cure shrinkage and excellent crack resistance, by compounding an unsaturated polyester, maleic anhydride, an epoxy rsin curable with imidazoles, and a high- molecular saturated polyester.
CONSTITUTION: The title composition useful as an insulation varnish, electrical insulation material, etc., is obtained by mixing (A) 100 parts by weight of an unsaturated polyester resin, (B) 0.1-0.2 part of maleic anhydride, (C) 2-200 parts, based on 100 parts of (A)+(B), of an epoxy resin curable with imidazole derivatives such as 2-ethyl-4-ethylimidazole, and (D) 1-12 parts, based on 100 parts of (A), of a high molecular weight saturated polyester resin such as Pylon-200 (Toyobo KK) having a molecular weight of 15,000-20,000.
