PDLC Film Roll

PDLC film is short for Polymer Dispersed Liquid Crystal. It is an upgraded version of the non-adhesive PDLC film, enhanced by adding a self-cling adhesive layer to the back of the standard film so it can be applied directly to glass. This electric switchable glass film is widely used as a modern privacy film on glass windows, allowing existing glass to be upgraded from transparent to opaque.

When powered on, the smart tint PDLC film becomes clear; when powered off, the smart film privacy glass turns into a frosted film glass . For bulk installation and long-length applications, PDLC film is also available in PDLC film rolls. PDLC film in roll can be cut by yourself and it is cheap cost.

Microfiber cloth

Alcohol

Squeegee

Measuring tape

Multimeter (for power testing)

Insulation tape / wiring tools

transformer (depending on film spec)

2. Environmental Conditions

Never cut through the busbar.

5. Installation Methods

Self-adhesive PDLC Film (Dry Installation)

STEP 1: Ensure the PDLC Smart Self-Adhesive Film on a clean flat surface.

STEP 2: Make sure that the adhesive side is facing up. Do not remove the protective layer one time until you finished installation. The adhesive side is usually marked with a label or a red tape.

STEP 3:Use a microfiber cloth with alcohol clean and remove dust and fingerprints from the glass surface before applying the glass film.

STEP 4:Glass film is made up of 2 internal layers (the active film) and two very thin, outer protective films that peel away for the installation.

STEP 5: Check the glass film - the "front" of the film will have electrical wires across the bottom. pull away the top corners of the film on the BACK to reveal the adhesive side very carefully. Do not pull the back film all the way off.

STEP 6: Remove the top corners of the protective layer from the adhesive side of the glass. Using the supplied squeegee, press firmly along the top and continue to press down to fully apply the film. Peel away the protective layer as the film is applied. This technique will help prevent air pockets in your film.If finding air bubbles, peel off the film with squeegee little by little ,make sure no air bubbles.

STEP 7: Once the PDLC film is stick on, gently peel off the protective film from the top layer.Connect the power supply to check the film is powered.

STEP 8: Seal edges with glass silicon(non acidic),neutral glass silicone.When the film is power off, it will appear opaque. When the film is power on, it is transparent.
