Title (EN) FORMABLE HARD COATED PC/PMMA COEXTRUDED FILMS
(FR) FILMS FAÇONNABLES DE PC/PMMA COEXTRUDÉS À REVÊTEMENT DUR
Abstract:
(EN) The present invention provides a formable hard coating composition, comprising a binder, comprising at least one acrylate oligomer and at least one monofunctional acrylate monomer and a crosslinking agent, comprising at least one multifunctional acrylate or methacrylate monomer. Furthermore, the present invention provides a coated film comprising a coextruded PC/PMMA film and a coating obtained by coating with the hard coating composition, wherein the coating has a dry film thickness according to ASTM B499 in the range of from ≥ 1 to ≤ 6 µm and preferably a crosslink density in the range of from ≥ 2 · 10-3 to ≤ 13 · 10-3. The coated films exhibit a combination of good formability and pencil hardness, solvent and chemical resistance which makes it particular useful for applications such as in-mold decoration processes.
(FR) La présente invention concerne une composition de revêtement dur façonnable, comprenant un liant, comprenant au moins un oligomère acrylate et au moins un monomère acrylate monofonctionnel et un agent de réticulation, comprenant au moins un monomère acrylate ou méthacrylate multifonctionnel. En outre, la présente invention concerne un film revêtu comprenant un film de PC/PMMA co-extrudé et un revêtement obtenu par revêtement avec la composition de revêtement dur, le revêtement présentant une épaisseur de film sec selon la norme ASTM B499 dans la plage de ≥ 1 à ≤ 6 µm et, de préférence, une densité de réticulation dans la plage de ≥ 2 · 10-3 à ≤ 13 · 10-3. Les films revêtus présentent une combinaison d'une bonne aptitude au façonnage et d'une bonne dureté au crayon, d'une bonne résistance aux solvants et aux produits chimiques qui les rendent particulièrement utiles pour des applications telles que des procédés de décoration dans le moule.
