Abstract

new glass coating system, containing gamma-glycidoxypropyltrimethoxysilane/Cr3+ (system I:GLYMO/ Cr3+) and gamma-glycidoxypropyltrimethoxysilane/N-aminoethyl-3-aminopropyltrimethoxysilane/Cr3+ (System II:GLYMO/DAMO/Cr3+), was synthesized by the sol-gel technique for UV light absorption applications. UV-visible spectroscopy (UV-VIS) was utilized to investigate the optical properties of coating materials. Especially system II showed very low transmission in the UV wavelength regions (300-400 nm) after thermal treatment of the coated surface. The UV transmission property of surfaces did not change at 80, 100, 450 or 500 degrees C, but a T value as low as 0.07% was obtained between 150 and 450 degrees C.
