Architectural window Film thickness from 0.0125mm to 0.5 mm thick, mainly look at its functional structure combination, because the building window film is multilayer ultra-thin high transparent polyester film by dyeing, magnetron sputtering, laminated laminating and other processes, so the film function of the window film, its actual effect is different.
1, anti-wear layer: The composition of wear-resistant polyurethane, hardness up to 4 H;
2, with color pet safety base: from High-strength, high transparent pet and pigment melt extrusion biaxial tensile system, because the pigment sandwiched in the pet film, can prevent oxidation discoloration, life of up to 8 years;
3, Metal insulation layer: In the pet film through vacuum evaporation or vacuum magnetron sputtering metal aluminum, silver, nickel and so on infrared has a high reflectivity of nano-metal layer;
4, composite adhesive: By the weatherability of a good high transparent polyurethane adhesive composition;
5, UV absorption layer: by special UV absorbent composition, can block 99% of ultraviolet rays;
6, transparent pet safety base: by High-strength, high transparent PET film composition, the purpose is to clamp the metal layer in the middle, to prevent metal oxidation, prolong the life of metal film;
7, the installation of adhesives: by a good weatherability high transparent acrylic ester adhesive composition;
8. High-transparent pet off-film.
