How do 3M Ultra Safety and Security Window Films work?
3M Ultra Safety and Security Window Films are designed to make glass shatter-resistant by holding the glass pieces together when broken. Different from 3M Sun Control Window Film, 3M Ultra Safety and Security Window Films are made with thicker polyester and a much thicker, more aggressive adhesive system. The 3M Ultra Safety and Security Window Films are unique in the industry: they are built using a special micro-layered polyester technology which increases the film’s tear resistance significantly. The impact and tear resistance of 3M Ultra Safety and Security Window Films outperforms other films of similar thickness known to 3M.
