Product Overview
The Westglass Photochromic Film Series leverages photochromic molecular technology and high-vacuum sputtered nano-coating processes to enable seamless, UV-triggered light transmittance adjustment (20%–75% visible light transmittance), delivering intelligent reversible switching between "clear" and "shaded" states. With a 99%–100% UV blocking rate and 80%+ infrared reflectance, it’s optimized for applications like building curtain walls, automotive sunroofs, and marine windows. Backed by a 5-year warranty, it combines energy efficiency, safety, and dynamic aesthetics to redefine smart light control.
