Glass window film structure and characteristics

1. Anti-wear layer: Composed of wear-resistant polyurethane with a hardness of up to 4H;
2. Colored PET safety base layer: made of high-strength, highly transparent PET polyester and pigment melt-extrusion biaxial stretching. Since the pigment is sandwiched inside the PET film, it can prevent oxidation and discoloration and has a lifespan of up to 8 years;
3. Metal insulation layer: Nano-scale metal layers with high reflectivity for infrared rays such as aluminum, silver, and nickel are deposited on the PET film through vacuum evaporation or vacuum magnetron sputtering;
4. Composite adhesive: composed of polyurethane adhesive with good weather resistance and high transparency;
5. UV absorbing layer: composed of special UV absorbers, which can block 99% of ultraviolet rays;
6. Transparent PET safety base layer: It is composed of high-strength and highly transparent PET polyester film. The purpose is to sandwich the metal layer in the middle to prevent metal oxidation and extend the life of the metal film;
7. Installation adhesive: composed of acrylic adhesive with good weather resistance and high transparency;
8. Highly transparent PET release film.
