Title (EN) ACRYLIC POLYVINYL ACETAL FILMS COMPRISING A SECOND LAYER
(FR) FILMS D'ACÉTAL POLYVINYLIQUE ACRYLIQUE COMPRENANT UNE SECONDE COUCHE
Abstract:
(EN) A film is described comprising a first film layer having a Tg ranging from 30°C to 60°C. The first film layer comprises a (meth)acrylic polymer and polyvinyl acetal polymer composition. The film further comprises a second layer proximate the first film layer. The second layer is different than the first film layer. The second may be a cured (meth)acrylic polymer film or coating; a backing such as thermoplastic polymer, woven or nonwoven fabrics, metal foils, paper, foams; or a coverfilm such as a fluoropolymer.
(FR) L'invention concerne un film comprenant une première couche de film présentant une Tg allant de 30 °C à 60 °C. La première couche de film comprend un polymère (méth)acrylique et une composition de polymère d'acétal polyvinylique. Le film comprend en outre une seconde couche à proximité de la première couche de film. La seconde couche est différente de la première couche de film. La seconde couche peut être un film ou un revêtement de polymère (méth) acrylique durci ; un support tel qu'un polymère thermoplastique, des tissus tissés ou non tissés, des feuilles métalliques, du papier, des mousses ; ou un film de couverture tel qu'un fluoropolymère.
