Product Specification

Product Overview

The Westglass Photochromic Film Series is an innovative functional film that integrates smart light adjustment, energy-efficient protection, and aesthetic design. Its core technology relies on special photochromic materials within the film, which undergo reversible molecular structural changes in response to ambient UV intensity—dynamically adjusting light transmittance: darkening rapidly in strong sunlight to block glare and restoring high clarity in low light for seamless, stepless switching.

Balancing indoor and outdoor light levels, it reduces glare for enhanced visual comfort while cutting air conditioning energy use through intelligent heat regulation. Ideal for applications in architectural windows, automotive glass, and curtain walls, it sets a new standard for adaptive light management.

Core Advantages

1.     Intelligent Dynamic Dimming for Adaptive Light Control

• Stepless Dimming Response System:
  • UV-triggered technology enables real-time transmittance adjustment between 75%–20% (customizable), balancing indoor light levels: reducing glare in bright conditions and preserving natural light in low light, eliminating the mechanical limitations of traditional shading devices for all-weather comfort.
• Rapid Response & Long-Term Stability:
  • Withstands 5,000+ color cycles without degradation, ensuring 5+ years of consistent performance—ideal for high-UV regions.

2.     Energy Efficiency & Environmental Protection

• Dual Light-Heat Blocking:
  • Thermal Insulation: ≥80% infrared blocking reduces solar heat gain, cutting AC load and achieving 15%–30% energy savings—aligned with green building and electric vehicle efficiency standards.
  • Interior Protection: Blocks ≥99% harmful UV rays, preserving furniture, automotive interiors, and artworks from fading and aging.
• Zero-Energy Green Operation:
  • Driven solely by natural light—no external power or complex systems required, minimizing carbon footprint from the source.

3.     Safe & Eco-Friendly Materials

• Uses non-toxic, formaldehyde- and benzene-free raw materials, emitting no pungent odors after installation to safeguard indoor and cabin air quality.

4.     Superior Optical Performance

• High-Transparency Foundation:
  • Haze <1% in the clear state ensures unobstructed views and natural light intake; transforms to neutral tones (gray, charcoal, gray-blue) when dimmed, seamlessly matching modern architectural and automotive glass aesthetics.
• Color Stability Technology:
  • Nano-level material formulation controls color coordinate shifts, avoiding common issues like color deviation or spots for consistent visual appeal over time.

5.     Effortless Installation & Extreme Durability

• Self-Adhesive Lightweight Design:
  • Low-tack pressure-sensitive adhesive applies directly to glass surfaces, boosting installation efficiency by 50% with support for dry/wet application on curved surfaces (e.g., car sunroofs, arched curtain walls) for bubble-free edges.
• Extreme Environment Adaptability:
  • Operates stably in -40°C–80°C and high humidity (95% RH), resisting salt spray—suitable for polar, tropical, and coastal climates.
  • 3mil+ thickness (customizable multi-layer structure) bonds shattered glass fragments, reducing splash risks for high-safety applications; surface hardening treatment enhances scratch resistance by 30% for easy maintenance.

6.     Multi-Functional Integration

• Noise Reduction:
  • Multi-layer structure attenuates 20–30 dB of ambient noise, particularly effective against low-frequency traffic noise, enhancing privacy in homes and luxury vehicles.
• Safety Reinforcement:
  • Enhances glass impact resistance, delaying breakage; paired with explosion-proof films, creates a dual safety barrier for high-security environments like banks and government buildings.

Application Scenarios

1.     Architectural

• Windows & Curtain Walls: Replaces traditional blinds/shutters in offices, hotels, and luxury homes for adaptive light control, energy savings, and enhanced comfort; neutral tones complement glass curtain wall designs for aesthetic consistency.
• Sunrooms & Skylights: Solves overheating and glare from direct sunlight, preserving interior views and protecting furniture from UV damage for year-round comfortable spaces.

2.     Transportation

• Automotive Glass: Reduces light abruptness in tunnels/sunny conditions to minimize driver fatigue; improves heat insulation for electric vehicles, extending battery range through lightweight design.
• Rail & Marine: Enhances passenger experience in high-speed trains and cruises with dynamic light control and noise reduction.

3.     Specialized Protection

• Optical Equipment: Used in goggles and face shields for auto-adjusting transmittance, protecting eyes from intense light in outdoor sports and industrial work.

Packaging Specifications

• Standard Rolls: 1.52m×30m / 1.52m×60m; width/length customization available.
• Protective Packaging: Inner/outer PE films + rigid paper core to prevent scratches or moisture during transit.

Storage Guidelines

• Store in a cool, dry place away from direct sunlight.
• Keep sealed and avoid contact with strong acids, alkalis, or volatile chemicals.
