Types of PDLC Switchable Products
There are two distinct smart glass products that utilize PDLC technology. Usage of each would depend upon the specific needs of a project. Generally speaking, for quick retrofits with low or moderate costs, self-adhesive films would be the right option. Alternatively, for new builds and renovations meant to last, the laminated PDLC glass would likely be the better choice. Here we will take a quick look at these two product types: laminated switchable PDLC glass and self-adhesive switchable PDLC film.
Laminated Switchable PDLC Glass
There are three different types of glass in laminated switchable PDLC glass:
- Annealed (weakest)
- Chemically strengthened (about two times stronger)
- Tempered glass (about four times stronger)
All three will exude a greenish tint due to the iron content in the glass. Annealed and tempered glass can be with a low-iron content, which would give those types a whiter appearance.
Self-Adhesive Switchable PDLC Film
With self-adhesive switchable PDLC film, the adhesive layer can paste directly onto the window, just like a window tint. The self-adhesive film utilizes a dry, or a nonaqueous, application. That is, no water or other aqueous solutions are needed to apply the film to an existing glass panel. Care should be patient to properly insulate the wiring so as to avoid electrical shock.
Smart film is a wonderful technology that offers many benefits, but as with any product, there are some warnings and precautions you should be aware of:
Installation: Incorrect installation can damage the film or reduce its lifespan. Suggestion that have a professional install the film or to carefully follow the manufacturer’s instructions if doing it yourself.
Cleaning: Smart film is clean with a soft cloth and non-abrasive cleaning products. Avoid using sharp objects or abrasive materials on the film as they can scratch or damage it.
Power Supply: Always use the recommended power supply and voltage for your smart film. Using an incorrect power supply can damage the film and void the warranty.
Temperature: Extreme temperatures can damage the film. Avoid installing the film in places where it will be exposed to high heat or freezing temperatures.
Handling: Handle the film with care. Folding or creasing the film can damage it.
Moisture: While some smart films are water resistant, they are not waterproof. Avoid installing them in places where they will be exposed to constant moisture.
Repairs: If the film is damaged, it’s best to have it repaired or replaced by a professional. Attempting to repair the film yourself could lead to further damage.
