How to Install Self adhesive PDLC Film?

What You Need to Know Before You Start

Personnel preparation: For non-professionals, it is recommended to have two individuals for installation. One person is responsible for lowering the film, while the other person is responsible for sliding away the bubbles. Professional personnel can handle the installation alone. For widths greater than 1.2m, it is advisable to have 2-3 individuals install together.
Environment preparation: Please make sure the work environment is as clean and dust-free as possible. Dust will easily lead to bubbles between the PDLC film and the glass surface. In front of the glass, you need a free space equal to the height of the glass itself to be able to move easily.
Dry installation process: Installing adhesive PDLC film is a dry process. Never use water; instead, use 99% isopropyl alcohol (industrial alcohol) to clean glass surfaces. Do not operate until the glass surface is 100% dry!
Protective layer handling: Please refrain from removing the protective layer (self-cling side) of the PDLC film until you are prepared to install the smart film. Keep the protective layer (non-cling side) intact until the installation is finished.
Avoid chemical cleaners: Avoid using any chemicals or abrasive cleaners on the smart film surface and glass surface, due to they may corrode the PDLC film. We recommend using either anhydrous alcohol or 99% Isopropyl Alcohol along with a lint-free cloth to clean the glass surface..
Careful Film handling: To prevent delamination, it’s important to handle the film edges with care. Never fold, bend, or curve smart film. Ensure that the film is kept flat and straight as demonstrated below.

Tools and Equipment You Need to Get Started

Measuring tape(optional): Use a measuring tape to determine the dimensions of the glass surface you want to cover.
Cutting tool(optional): You’ll need a cutting tool to cut the self-adhesive PDLC film to the desired size and shape. A utility knife or a pair of scissors can be used for this purpose.
Cleaning solution and cloth: Before applying the self-adhesive PDLC film, you’ll need to clean the glass surface thoroughly. Use a glass scraper with 99% isopropyl alcohol and a lint-free cloth to remove any dust, dirt, or debris.
Scratch-free Squeegee: When applying the self-adhesive PDLC film, you’ll need a felt edges squeegee to remove any air bubbles or wrinkles. This will help ensure the film is evenly applied and there are no gaps or overlaps.

General Steps For Installing Self-Adhesive PDLC Film

1. Measure and trim the film if necessary: It is advisable for the dimensions of the smart film to be 2mm shorter than the visible area of the glass. Use a cutting tool such as a utility knife or a pair of scissors to cut the self-adhesive PDLC film to the desired size and shape.
2. Testing the film: Test the self-adhesive PDLC film to ensure it’s working properly. Connect to the power supply and switch the film from opaque to clear to test if the film is responding correctly.
3. Clean the glass surface: Use a cleaning solution and a lint-free cloth to clean the glass surface thoroughly. Make sure to remove any dust, dirt, or debris that may be present.
4. Dry the glass surface: After cleaning the glass surface, use a dry lint-free cloth to remove any moisture or residue. The glass surface should be completely dry before applying the self-adhesive PDLC film.
5. Apply the film to the glass surface: Carefully apply the self-adhesive PDLC film to the glass surface, making sure to avoid air bubbles, wrinkles, or gaps.
- (5.1) Peel the backing off the film: Once the film is cut to size, peel off the backing about 10cm at the top to expose the adhesive side of the film.
- (5.2) Align the film and start applying: Align the film edge with the top edge of the glass and slowly remove the backing layer, allowing the film to adhere to the glass under its own weight of 8-10cm at a time. Then, use a scraper squeegee in a side-to-side motion, starting from the top and gradually moving down to remove any air bubbles. If any air bubbles are visible, lift the film carefully to avoid grabbing dust particles and let it lay back down under its own weight. If air bubbles persist, check for dust particles on the cling and remove them with adhesive tape or a small piece of tape.
- (5.3) Removing air bubbles and wrinkles: After applying the self-adhesive PDLC film, it’s important to use a squeegee or credit card to remove any air bubbles or wrinkles. Not doing so can result in an uneven installation that looks unprofessional.
6. Test the film after installation: After installing the self-adhesive PDLC film, connect it to electricity, and test it to ensure it’s working properly. Make sure the film is responding correctly to the power supply and that the level of privacy is what you desire.
7. Sealing the film edge(Optional): Suggest sealing the edge of self-adhesive PDLC film with neutral silicone sealant(Using brand TOSSEAL 381, TOSSEAL 83, or Dow Corning 799), to isolate it from water and humidity.

Daily Care and Maintenance Tips:

Keep the film dry: Self-adhesive PDLC film should be kept dry at all times. If water or any liquid spills on the film, clean it immediately with a dry cloth to avoid any damage. Or use non-acid glass silicone sealant to seal PDLC film edge totally, then can prevent water and liquid from going inside the film, make sure the smart film works stable for a long time.
Clean the film regularly: Regular cleaning of the self-adhesive PDLC film is important to keep it looking great and functioning properly. Use a cleaning solution and a lint-free cloth to remove any dirt, dust, or fingerprints.
Avoid using abrasive cleaners: When cleaning the film, avoid using abrasive cleaners or materials that could scratch the surface of the film. Use a mild cleaning solution or water and a soft cloth to clean the film.
Avoid using harsh chemicals: Harsh chemicals such as ammonia or bleach should not be used on the self-adhesive PDLC film as they can damage the film. Use a mild cleaning solution or water and a soft cloth to clean the film.
Avoid exposing the film to extreme temperatures: Self-adhesive PDLC film should not be exposed to extreme temperatures as this can damage the film. Avoid placing the film in areas where it will be exposed to direct sunlight or near heat sources such as radiators or stoves.
Avoid applying pressure to the film: Do not apply any pressure to the film as this can damage the film or cause delamination. When cleaning the film, use a gentle touch and avoid pressing too hard.
Protect the film from scratches: Avoid using sharp objects near the self-adhesive PDLC film as this can scratch or damage the surface. Be careful when installing or removing objects near the film.
