3M Security Window Film

3M Security Window Film works on the same principle as the binding agent in automotive glass. The binding agent keeps the glass from shattering upon impact, just like a rock that hits your windshield may cause a hole, but the overall glass piece remains intact. Laminated security glass consists of two pieces of glass with a PVB layer in-between, and the makeup is glued together under pressure in a tank called an autoclave. Security film creates similar protection, but rather than replacing your existing non-security glass with laminated glass, you can add security window film. Think of it as an aftermarket laminated glass application.
