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 that can be used 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 made 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 is applied 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 exercised to properly insulate the wiring so as to avoid electrical shock.
