1.0 Scope

This specification is for acombination safety and security window film with sun control: aglass shatter resistant and abrasion resistant window film which,when applied tothe interior window surface,will helphold broken glass together, reduce the ultra-violet light transmission, and reduce the solar heat gain of solar energy through the window. This is an easily applied tear-resistant safety and security window film with sun control, exhibiting low internal reflectivity, which is useful for increased measure of protection in a broad range of applications, including basic glass fragment retention, spontaneous glass breakage, seismic preparedness, and safety glazing applications,and bomb blast mitigation. Certain applications may require the film be used in conjunction with a film attachment system. The film shall be called 3MScotchshield Safety and SecurityWindow Film, Ultra Night Vision S25.
