摘要：
A high optical quality polyurethane coating layer, with self-repairing and fog-resistant properties, utilized for panes made of glass and/or plastic materials. The layer is formed from a reactive mixture composed 10 to 75% by weight of a biuret or an isocyanurate of 1,6 hexamethylenediisocyanate, having a content of about 15 to 25% weight of NCO radicals and having an average molecular weight between about 450 and 850 and comprised about 90 to 25% by weight of a polyalcohol component essentially comprised of a plurifunctional polyalcohol having about 0.4 to 17% of its percentage weight comprised of OH radicals, and having a molecular weight between about 200 and 15,000, and having ethoxy-propoxy chains, comprised 50 to 90% by weight of ethoxy radicals and 50 to 10% by weight of propoxy radicals.
