How do 3M® Scotchshield (Ultra) Safety and Security Window Films work?

3M® Scotchshield Ultra Safety and Security Window Films are designed to make glass shatter-resistant by holding the glass pieces together when broken. Compared to 3M® Scotchtint films, 3M® Scotchshield Window Films are made with thicker polyester and a much thicker, more aggressive adhesive, 3M® Scotchshield Ultra Films are unique in the industry; they are built using a special micro-layered polyester technology which increases the films’ tear resistance significantly. Pound for pound, the impact and tear resistance of Scotchshield Ultra films outperform all other films of similar thickness.  more
