Prior to the use of laminated windshields, one of the major safety concerns in driving was the possibility of occupants being injured by flying glass during an accident. Today, safety and security concerns of drivers have expanded to include having a vehicle window hit by a thrown brick or smashed by the crowbar of a carjacker. The polyester film has a proprietary, abrasion-resistant hard coating which provides outstanding long-term durability. Tempered glass, Butacite and polyester combine for strength and intrusion resistance. The coating (a glass-like finish layer) provides a high degree of abrasion resistance plus the smooth surface expected in window glass. SentryGlas Composite is heat and pressure laminated to a glass surface.
And given the investment motorists make in vehicle security systems, the window protection afforded by SentryGlas makes good sense to deter "smash and grab" theft of possessions and vehicle accessories.
SentryGlas Composite from DuPont, offering significant safety and theft-prevention benefits, is designed to give the kind of protection today's drivers need.		 This process, performed in a specialized factory, produces a high-quality glazing that will not delaminate, bubble or blister under exposure to direct sunlight.
It also blocks out up to 99% of harmful UV (ultraviolet) rays from the sun, thus helping to reduce fabric fading.
SentryGlas is strong, durable, and intrusion resistant.

DuPont SentryGlas Composite provides the advantages of laminated glass using a single sheet of glass bonded to a high-performance composite. As illustrated in the diagram on this page, it is an engineered 3-layer shield. It combines an interlayer of clear, strong polyester film.

Protection against spalling.

SentryGlas Composite is a viable deterrent to glass spalling. (Spalling is the shower of glass pieces that occur when glass is penetrated.) Super-tough SentryGlas contains glass breakage and prevents the airborne glass fragments from spraying people inside the vehicle. In fact, when combined with bulletproof laminated construction, SentryGlas provides additional anti-spalling protection.
