GEL COATING RESIN COMPOSITION, PRODUCTION OF GEL-COATED FIBER-REINFORCED PLASTIC MOLDING, AND MOLDING

摘要

PURPOSE:To obtain the title composition which can give a gel coat prevented from lifting by mixing an unsaturated polyester resin with a polyisocyanate compound in a specified ratio. CONSTITUTION:This composition is prepared by mixing 100 pts.wt. unsaturated polyester resin (e.g. a resin prepared by reacting maleic anhydride and phthalic anhydride with propylene glycol and diethylene glycol) with 0.5-5.0 pts.wt. polyisocyanate compound (e.g. hexane 1,6-diisocyanate).
