Product Overview
The Westglass Dark Gray PDLC Self-Adhesive Smart Dimming Film is based on PDLC (Polymer-Dispersed Liquid Crystal) technology, enabling one-touch instant switching between "power-on clear" and "power-off frosted" states via electric field control. When power off, it presents a dark gray frosted state for effective privacy shielding; when power on, it achieves ≥55% light transmittance for clear visibility.
Supporting customized sizes and patterns, this film adapts to glass curtain walls, office partitions, high-end residences, and other scenarios. The dark gray tone combines professionalism with understated aesthetics, integrating smart dimming with decorative functionality for premium environments.

Product Advantages
1. High Scenario Versatility
- Privacy & Projection Modes: Frosted state serves as a HD projection screen for commercial windows and exhibitions; clear state enables dynamic product displays.
- Energy-Efficient Thermal Control: Blocks ≥60% infrared and ≥99% UV rays, reducing indoor temperatures by 8–10℃ in summer and cutting AC energy use. Only 4–5W/m² power consumption aligns with low-carbon goals.
- Zoned Dimming Customization: Independent control of light transmittance for car sunroofs, office partitions, and other personalized needs.
2. Superior Performance
- Durability: High-quality adhesive layer resists impact and wear, with a lifespan exceeding 10 years.
- Premium Visuals: Dark gray tone enhances aesthetics, with clarity close to regular glass when powered on, ideal for high-end displays.
3. Effortless Installation & Lightweight Design
- Self-adhesive technology allows direct application to existing glass without lamination, supporting dry installation and automatic air release. 70% lighter than traditional laminated dimming glass, reducing transportation costs—perfect for retrofits.
4. Diverse Control Options
- Compatible with traditional switches, WiFi, voice, temperature sensors, and remote control for smart home and IoT integration.
5. Reliable Performance & Safety
- Rapid Response: State switching in ≤200ms for instant needs.
- Extreme Weather Resistance: Stable performance in -30℃ to 65℃, resisting fading and bubbling.
- Explosion-Proof: Enhanced impact resistance prevents glass shards from splashing, ensuring safety.
Application Scenarios
