Transparent coating of flexible, elastic polyurethane for transparent glass or synthetic resin substrates |
摘要 |
A transparent coating for windows or other transparent substrates made of glass or synthetic resin, consisting of a flexible elastic polyurethane, serves as a shatterproofing coating for substrates made of silicate glass or as a coating improving the scratch resistance of substrates made of synthetic resin. To reduce or prevent the formation of a deposit of moisture on the surface of the coating, the polyol component of the reaction mixture for preparing a coating pursuant to the invention consists of a difunctional sulfonated polyether polyol containing approximately 1 to 10% of OH groups by weight and a trifunctional polyol containing approximately 8 to 12% of OH groups by weight and having an average molecular weight of approximately 400 to approximately 1000 g/mole.
