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.
