Self-adhesive multi-layer film for anti-graffiti protection

摘要

The multilayer self-adhesive film comprises a multilayer complex (1) consisting of an anti-graffiti protection surface layer constituted of transparent fluoropolymer film (2), a first layer of non-halogenated transparent adhesive polymer (3), a decorative support film constituted of a non-halogenated polymer (5), and a second adhesive layer sensitive to the pressure of non-halogenated polymer. The multilayer complex has manually stretchable properties at room temperature, and elongation properties including tensile strength of less than 800 N/m to obtain an elongation of 20%. The multilayer self-adhesive film comprises a multilayer complex (1) consisting of an anti-graffiti protection surface layer constituted of transparent fluoropolymer film (2), a first layer of non-halogenated transparent adhesive polymer (3), a decorative support film constituted of a non-halogenated polymer (5), and a second adhesive layer sensitive to the pressure of non-halogenated polymer. The multilayer complex has manually stretchable properties at room temperature, and elongation properties including tensile strength of less than 800 N/m to obtain an elongation of 20%. The multilayer complex comprises anti-graffiti fluorinated polymer film having a thickness of 10-30 wt.%, non-halogenated polymer as a decorative support film (4) and first and second adhesive layers having 20-60 wt.% of thickness. The non-halogenated polymer of the decorative support film is an acrylic polymer film having a thickness of 50-75 wt.%. The tensile strength of the non-halogenated polymer film of decorative support is less than or equal to 1000 N/m and a rupture elongation of greater than 100%. The adhesive layers comprise a polyacrylic adhesive. The non-halogenated polymer of supporting film is a film obtained by coating with identical elongation properties in length and width. The first adhesive layer has a weight of less than or equal to 40 g/m 2>with an adhesion force on glass greater than 500 N/m, and the second layer of adhesive has a weight of less than or equal to 50 g/m 2>with adhesion force on glass less than 2000 N/m. The second adhesive layer is applied to a temporary protection liner (6) including a silicone coated paper sheet coated with a nonstick coating.
