PPG Performance Glazing Launched as Standard on Lincoln Aviator

LINCOLN AVIATOR Pittsburgh-based PPG Industries has designed and produced laminated front sidelites for the new Lincoln Aviator. According to the company, it is the first time enhanced performance glazing will be standard on a North American vehicle.

According to Ernest Hahn, PPG vice president of automotive glass, the PPG windows take up to 20 times longer to penetrate than standard tempered windows, and they can attenuate sound by up to 6 decibels.

"We worked with Lincoln to achieve a laminated window thin enough to fit into the standard door channel while affording the enhanced security and sound benefits," Hahn said. "The windows represent a technological breakthrough because they are the thinnest automotive laminated side windows in commercial production—less than 4 mm—allowing them to be a drop-in replacement for standard tempered parts."

PPG produces the laminated windows at its Tipton, Pa., glass-fabricating plants. The windows are made with two pieces of heat-strengthened glass laminated with a vinyl inner ply.

Torvec Uses Dartmouth's Technology to Design Windshield of the Future
Windshields and backlites could have a revolution in store—a thin interlayer that may actually prevent ice from forming on the glass. The technology behind the system was discovered by Dartmouth College ice physicist and professor Victor Petrenko, who discovered through research that ice sticks to materials by forming an unbreakable, but barely perceptible, electric bond; when that electric charge is reversed, the ice won't stick.

The college has licensed the discovery to Torvec Inc. of Rochester, N.Y., to develop it further for land-based applications. With this knowledge, the company hopes to soon release an invisible windshield polymer that will repel ice from the surface. 

According to a news release issued by Torvec, the polymer conducts a low-voltage current, comparable to that used to run cars' clocks. Thus, the windshield will repel the ice without any exterior assistance. The polymer would be placed between a windshield's two thin glass lites during both the manufacture of OEM glass and replacement windshields, according to the company.

Diamon-Fusion Applies Hydrophobic Coating to AGP Glass
Diamon-Fusion International of San Juan Capistrano has begun applying its patented hydrophobic coating to American Glass Products Co.'s (AGP) bullet-resistant automotive glass under their exclusive licensing agreement. AGP's glass is utilized in a number of popular vehicles, including certain upscale models manufactured by Audi, BMW, Cadillac, Chevrolet, Chrysler, Dodge, Ford, General Motors, Honda, Hyundai, Infiniti, Isuzu, Jaguar, Jeep, Land Rover, Lexus, Lincoln, Mazda, Mercedes-Benz, Mercury, Mitsubishi, Nissan, Peugot, Renault, Toyota, Volkswagen and Volvo.
The hydrophobic coating was developed to improve visibility during rain storms and provide drivers with added reaction time.
