Why PDLC Smart Film?
Privacy on Demand
Switch between transparent and opaque modes instantly for complete privacy control.
UV Protection
Blocks up to 99.9% of harmful UV rays, protecting interior from fading and damage.
IR Rejection
Advanced infrared rejection up to 100% keeps your vehicle cool and comfortable.
Smart Control
Compatible with vehicle power systems for seamless integration and control.
How It Works
Power Off — Privacy Mode
PDLC molecules are randomly aligned, scattering light and creating an opaque, frosted appearance for complete privacy.
Power On — Transparent Mode
When electricity is applied, molecules align uniformly, allowing light to pass through for crystal-clear visibility.
Instant Switching
Toggle between modes in milliseconds using a simple switch or smart control system.
Smart Integration
Compatible with vehicle power systems and can be controlled via switch, remote, or mobile app.

Installation Steps
Professional Tips
Work in a dust-free environment — a garage with sealed doors is ideal for automotive installations.
Use a heat gun on low setting to contour film around curved glass surfaces. Keep the gun moving to avoid overheating.
Apply adhesive promoter to glass edges before film application — this ensures long-term adhesion on vehicle glass.
Leave 2-3mm gap between film edge and glass edge to account for thermal expansion during vehicle operation.
Maintenance & Care
Proper maintenance ensures optimal performance and extends the lifespan of your PDLC smart film.
Regular Cleaning
Use a soft microfiber cloth with mild soapy water. Gently wipe the film surface in one direction. Avoid circular motions that can create swirl marks.
Do
- Use soft microfiber cloths
- Use mild soap or glass cleaner
- Wipe in one direction
- Clean monthly for best results
Don't
- Never use abrasive cleaners or scrub pads
- Never use ammonia-based cleaners (Windex)
- Never use razor blades or sharp objects
- Never apply excessive pressure
Stain Removal
For stubborn stains, use isopropyl alcohol (70%+) on a soft cloth. Apply gently and rinse with clean water. Test on a small area first.
Do
- Test cleaning solution on small area first
- Use isopropyl alcohol for tough stains
- Rinse thoroughly after cleaning
- Dry with clean microfiber cloth
Don't
- Never use acetone or solvent-based cleaners
- Never use bleach or harsh chemicals
- Never let stains sit for extended periods
- Never use paper towels (they scratch)
Protection
PDLC film is durable but requires proper care. Avoid contact with sharp objects. Protect edges from peeling by keeping them clean and dry.
Do
- Keep sharp objects away from film surface
- Protect film edges from moisture intrusion
- Use window treatments to reduce UV exposure
- Inspect edges quarterly for adhesion issues
Don't
- Never apply stickers or adhesive tapes directly on film
- Never allow pets to scratch the film surface
- Never use film on damaged or cracked glass
- Never ignore edge lifting — address immediately
Electrical Care
Ensure control box has proper ventilation. Check wiring connections annually. Keep control box away from moisture and extreme heat sources.
Do
