Product Overview

The Westglass Photochromic Film Series is an intelligent light-adjusting solution that automatically modifies light transmittance by sensing changes in UV intensity from sunlight, enabling seamless switching between "transparent" and "shaded" states. This dynamic adjustment regulates heat transfer for energy efficiency, while auto-adjusting color to optimize indoor lighting and visual comfort. Core technology relies on reversible molecular structural changes in special photochromic materials within the film—darkening rapidly in strong light and restoring clarity in low light. Combining energy savings, safety, and aesthetics, it’s ideal for applications like building windows, automotive glass, and curtain walls.

Core Advantages

1.     Smart Dynamic Light Adjustment

• Seamless Dimming: UV-triggered color change with auto-adjustable light transmittance (e.g., 75%–20% for visible light), balancing indoor comfort and eliminating glare.
• Rapid Response: Activates in seconds with no performance degradation after repeated cycles, enduring 5+ years for day-night and weather changes.

2.     Energy Efficiency & Eco-Friendliness

• Heat & UV Blocking: ≥90% infrared blocking and 99%–100% UV blocking protects furniture and interiors from fading/aging while reducing indoor heat buildup, cutting AC energy use by 15%–30%.
• Zero-Energy Operation: Driven by natural light—no external power required, aligning with green building standards.
• Safe & Non-Toxic: Uses eco-friendly materials with no pungent odors, certified to international safety standards for indoor air quality.

3.     Superior Optical Performance

• Crystal-Clear Transparency: Extremely low haze in the clear state ensures unobstructed views and natural light intake.
• Stylish Color Stability: Available in neutral tones like gray and charcoal, complementing modern architectural and automotive designs.

4.     Easy Installation & Durability

• Self-Adhesive Design: Applies directly to glass surfaces for quick, hassle-free installation.
• Extreme Weather Resistance: Performs in -40°C–80°C and high humidity, with a 5+ year color-changing lifespan—resistant to scratches and bending.

5.     Multi-Functional Protection

• UV Shield for Interiors: Prolongs the life of furniture and textiles by blocking aging UV rays.
• Noise Reduction: Multi-layer structure cuts ambient noise by 20–30 dB, enhancing indoor tranquility.
• Safety Reinforcement: 3mil+ thickness bonds shattered glass fragments, reducing splash risks for high-safety applications like skyscraper windows and car sunroofs.

Application Scenarios

• Building Windows & Curtain Walls: Replaces traditional blinds for smart lighting and energy-efficient cooling in offices, hotels, and homes.
• Automotive & Transportation: Reduces glare, enhances noise/heat insulation for vehicle windows/sunroofs, improving driving safety and comfort.
• Specialized Protection: Used in eyewear and face shields for UV defense and adaptive shading.

Packaging & Storage

• Packaging: Customizable rolls (1.52m*30m/60m).
• Storage: Store in a cool, dry place away from direct light—avoid high temperatures or strong acids/alkalis.
