3M™ Safety Film Safety S70 was designed for usage on the interior surface of windows. The film is visco elastic and obsolescence resistant. High resistance of the film to stretch and crack extension increases the resistance of glass to pressure, push and impacts. Even distribution of the sun’s rays effectively reduces the effect of dazzle. Besides, the film greatly significantly reduces the amount of UVA rays which are the main reason of discolouration.

3M™ Safety Films provide an effective protection from injuries or damage to items caused the fragments of broken glass. In case of glass breakage the fragments are hold due to the system of the adhesive.
