How do 3M™ Scotchshield™ (Ultra) Safety and Security Window Films work?
3M™ Scotchshield™ ULTRA Safety and Security Window Films are designed to hold glass fragments 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 and puncture resistance significantly. The impact and tear resistance of 3M™ Scotchshield™ ULTRA films outperform all other films of similar thicknesses.
