Window film structure and characteristics
Window film structure and characteristics
1. Anti-abrasion layer: composed of abrasion-resistant polyurethane, the hardness is up to 4H;
2. Color-bearing PET safety base layer: made of high-strength, high-transparent PET polyester and pigment melt extrusion bi-directional stretching, due to the pigment sandwiched inside the PET film, it can prevent oxidative discoloration, with a life span of up to 8 years;
3. Metal insulation layer: nano-scale metal layer with high reflectivity to infrared rays by vacuum evaporation or vacuum magnetron sputtering metal aluminum, silver, nickel, etc. on PET film;
4. Composite adhesive: composed of weather-resistant good highly transparent polyurethane adhesive;
5. UV absorbing layer: composed of special UV absorber, which can block 99% of ultraviolet rays;
6. Transparent PET safety base layer: composed of high strength, high transparent PET polyester film, the purpose is to sandwich the metal layer in the middle to prevent metal oxidation and prolong the life of the metal film;
7. Mounting adhesive: composed of good weather resistance and high transparent acrylate adhesive;
8. Highly transparent PET release film.
