3M Impact Protection Adhesive



Security films have traditionally been installed using a technique known as a daylight application. Film is applied to the window and bonded to the glass during the installation process. Excess film is then trimmed to fit against the window's gaskets to create a finished product with a daylight gap of approximately 1/16”-1/8”.

Consideration was then given to the fact that the entire glass pane could be blown or pushed out of the frame given a severe explosion or other trauma. Security film manufacturers responded to this additional threat by developing attachment systems that are meant to bond the film to the glass to the window frame. 3M Company’s attachment system is called Impact Protection Adhesive (IPA).

IPA is a high strength structural silicone adhesive to anchor the security film, glass, and window frame to each other. The anti-shatter film is applied to the glass in a fashion similar to that of a daylight application except that the gaskets are trimmed and the film's edges are inserted as close to the window frame as possible. A ½” bead of silicone is then applied flush against the frame to overlap the security film and take the place of the original gaskets.
