Abstract
Disclosed is a laminated film having: (a) a substrate; and (b) a bonding layer of ethylene polymer on one major surface of the substrate wherein the bonding layer is placed directly on the substrate or there is a (c) primer layer between the substrate and bonding layer. Also disclosed is a solar module made of such a laminated polymer film.
Claims23
A laminated film comprising:
- (a) a polyester substrate having a first surface and a second surface comprising polymers selected from the group consisting of polyC2-6 alkylene phthalates, polyC2-6 alkylene naphthalates, and mixtures or blends thereof;
- (b) an adhesive layer on the first surface of the polyester substrate;
- (c) a primer layer on the second surface of the polyester substrate, wherein the primer layer is less than 0.99 micron thick;
- (d) a bonding layer on the primer layer, wherein the bonding layer comprises a copolymer of ethylene and one or more monomers selected from the group consisting of C1-4 alkyl acrylates, C1-4 alkyl methacrylates, methacrylic acid, acrylic acid, glycidyl methacrylate, and maleic anhydride;
- and
- (e) a protective layer on the adhesive layer comprising a fluoropolymer with a tensile modulus of greater than 150 Kpsi.
