Highly durable coatings for automotive polycarbonate glazing

Scratch resistance analysis of coatings on glass and polycarbonate

“…The criteria for the automotive application of ΔH b 3% at 1000 revolution has not been met [4]. However, optimized multilayer stacks were described [5,6] being capable of fulfilling these demands.…”

Data on Specific Polymers

“…282 Silicone coating applied by the plasma-enhanced chemical vapor deposition process gives a 10 years durability. 280 PC/ABS blends were stabilized with HALS and concentration and distribution of nitroxide radical were determined. PC contains much larger concentration of radicals than ABS or its blend with PC.…”

Weathering of Compounded Products

“…The material for light lenses must have the highest possible light transmission, lack of color, and be haze free. 90 All automotive plastics must meet highly controlled color standards and color stability. 88 With colored lenses the precise coloring must be achieved.…”

“…90,100,105 Light lenses are being exposed in Florida and Arizona for 3 years, cleaned with soap at 3 months intervals and checked for light transmission. 90,100,105 Light lenses are being exposed in Florida and Arizona for 3 years, cleaned with soap at 3 months intervals and checked for light transmission.…”
