FOG AND FROST RESISTANT COATINGS WITH LOW COEFFICIENT OF FRICTION

A coating composition comprises a urethane resin, a water absorbent polymer, and a curing agent. The urethane resin is obtained by reaction of an isocyanate reactive compound having multi-epoxide functionality and an isocyanate. When applied to a substrate and thermally cured, the coating compositio...

Zusammenfassung:	A coating composition comprises a urethane resin, a water absorbent polymer, and a curing agent. The urethane resin is obtained by reaction of an isocyanate reactive compound having multi-epoxide functionality and an isocyanate. When applied to a substrate and thermally cured, the coating composition forms a transparent and smooth coating having permanent anti-fog property. Une composition de revêtement comprend une résine d'uréthane, un polymère absorbant l'eau et un agent de durcissement. La résine d'uréthane est obtenue par réaction d'un composé réactif à l'isocyanate ayant une fonctionnalité multi-époxyde et un isocyanate. Lorsqu'elle est appliquée sur un substrat et durcie thermiquement, la composition de revêtement forme un revêtement transparent et lisse ayant une propriété antibuée permanente.
