Title
(EN) AQUEOUS FLUOROPOLYMER GLASS COATING
(FR) REVÊTEMENT AQUEUX DE POLYMÈRE FLUORÉ POUR DU VERRE
Abstract
(EN)
The invention relates to an aqueous fluoropolymer coating composition for direct application to glass without the need for pre-treatment of the glass surface. The coating composition can also be used with other non-porous and porous substrates. The fluoropolymer coating contains a hydroxyl-functional fluoropolymer, and polyisocyanates. Preferably the coating composition also contains a water-dispersible hydroxyl functional polyurethane. The coating composition may exist as a 1-pack or a multi-pack coating system. The coating has excellent wet adhesion to glass, good weathering, chalking resistance, chemical resistance, and dirt pickup resistance.
(FR)
L'invention porte sur une composition aqueuse de revêtement de polymère fluoré pour application directe sur du verre sans besoin de prétraitement de la surface du verre. La composition de revêtement peut également être utilisée avec d'autres substrats non poreux et poreux. Le revêtement de polymère fluoré contient un polymère fluoré à fonction hydroxyle et des polyisocyanates. De préférence la composition de revêtement contient également un polyuréthane à fonction hydroxyle dispersible dans l'eau. La composition de revêtement peut exister sous forme d'un système de revêtement à un seul composant ou à plusieurs composants. Le revêtement a une excellente adhérence à l'état humide à du verre et de bonnes résistance aux agents atmosphériques, résistance au farinage, résistance aux produits chimiques et résistance à la rétention de salissures.
