A building material having a durable exterior finish comprising a substrate laminated with a fluorohydrocarbon protective film. The protective film provides the substrate with resistance to weathering and maintains the surface texture of the underlying substrate while providing an aesthetically pleasing and uniform pre-finish on the exterior surface. The protective film is bonded to the substrate using an adhesive composition comprised of a one-component moisture cure polyurethane or polyurea adhesive composition having a reactive isocyanate compound or a two component polyurethane or polyurea composition.
L'invention concerne un matériau de construction à revêtement extérieur durable, qui comprend un substrat revêtu d'un film protecteur fluorohydrocarboné. Le film protecteur permet au substrat de résister aux intempéries et maintient la texture de surface du substrat sous-jacent, tout en conférant un aspect préfini esthétiquement agréable et uniforme à la surface extérieure. Le film protecteur est collé au substrat au moyen d'une composition adhésive constituée d'un polyuréthanne à un composant durcissant à l'humidité, d'une composition adhésive à base de polyurée renfermant un composé d'isocyanate réactif ou d'une composition de polyuréthanne ou de polyurée à deux composants.
