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

  • Ensure control box has adequate ventilation
  • Check wiring connections annually
  • Keep control box dry and cool
  • Test switching function monthly

Don't

  • Never block control box ventilation
  • Never expose control box to direct water
  • Never modify wiring without professional guidance
  • Never exceed rated power capacity

Warranty & Lifespan

  • PDLC films are rated for 50,000+ switching cycles with proper care
  • 3-year warranty covers manufacturing defects and adhesive failure
  • Expected lifespan of 10+ years with proper installation and maintenance
  • Warranty does not cover damage from improper cleaning or unauthorized modifications

Frequently Asked Questions

Everything you need to know about our products.

What is PDLC smart film?
PDLC (Polymer Dispersed Liquid Crystal) film is a switchable smart film that transitions between transparent and opaque states when electrical current is applied or removed. When powered off, the liquid crystal molecules scatter light creating a frosted, opaque appearance. When powered on, molecules align uniformly allowing light to pass through for crystal-clear visibility.
How long does PDLC film last?
Our PDLC films are rated for over 50,000+ switching cycles and come with a 3-year warranty. With proper installation and maintenance, they can last 10+ years. The film is designed for continuous daily use in both automotive and architectural applications.
Is PDLC film safe for vehicles?
Yes, our automotive PDLC films are designed specifically for vehicle use, operating on low voltage (AC 24V) and meeting automotive safety standards. The film is 0.45mm thick and weighs only 350g/m², ensuring no impact on vehicle performance.
Can PDLC film be installed on any glass?
PDLC film can be applied to most flat or slightly curved glass surfaces. Automotive films are pre-cut for specific vehicle models (50cm × 100cm per piece), while architectural films are available in custom sizes up to 1.8m width × 50m length rolls.
How is PDLC film controlled?
PDLC film can be controlled via wall switch, RF remote control, mobile app, or integrated with smart home/building automation systems. Automotive kits include a power supply and switch. Architectural installations can integrate with BMS for automated control.
Does PDLC film block UV rays?
Yes, our PDLC films block up to 99.9% of UV rays in both transparent and opaque states, providing excellent protection against UV damage to interiors and occupants.
What is the difference between Full Kit and Half Kit?
A Full Kit includes 4 pre-cut films (50cm × 100cm each) plus power supply, covering all side windows. A Half Kit includes 2 films plus power supply, suitable for rear windows only. Both kits are designed for easy DIY installation.
What is the difference between Slice and Roll for architectural film?
Slice is custom-cut to your exact window dimensions (ideal for standard windows). Roll comes in widths of 1m/1.2m/1.5m/1.8m × 50m length (ideal for large projects or multiple windows). Both use dry self-adhesive backing for easy installation.
Can PDLC film be used as a projection screen?
Yes! When in the opaque (power off) state, PDLC film can serve as a rear projection screen. This is particularly useful for retail displays, conference rooms, and home theater applications.
What voltage does PDLC film require?
Automotive PDLC film operates on AC 24V (compatible with vehicle electrical systems). Architectural PDLC film operates on AC 60V. Control boxes (DT-CB30W to DT-CB500W) handle the voltage conversion from standard AC 110V/220V input.
How do I clean and maintain PDLC film?
Use only soft, lint-free cloths and non-ammonia, non-alcohol cleaners. Avoid abrasive materials, sharp objects, and harsh chemicals. For automotive installations, wait 30 days after installation before cleaning to allow adhesive to fully cure.
Is professional installation required?
Automotive Full/Half Kits are designed for DIY installation with included instructions. However, professional installation is recommended for best results. Architectural installations, especially Roll format, should be performed by certified installers for optimal performance and warranty coverage.
