CAMADA TRANSPARENTE DE COBERTURA DE POLIURETANO ELASTICO MACIO,COM EFEITO INHIBIDOR DE EMBACAMENTO PARA SUBSTRATOS TRANSPARENTES DE VIDRO E PLASTICO SINTETICO

摘要

The invention relates to a transparent anticondensation coating layer consisting of a flexible elastic polyurethane for windows and other transparent substrates made of glass or synthetic resin. The reaction mixture for the manufacture of the coating layer contains, besides a trifunctional polyisocyanate and a trifunctional polyol, a difunctional polyetherpolyol which is sulphonated or contains sulphonate radicals, a nonionic polyether-polysiloxane and a nonionic surfactant in the form of an ethoxylated fatty alcohol and/or an ethoxylated fatty amine.
