Abstract
A hydrophobic silicone coating composition includes a trialkoxysilane with trialkoxy functionality, a polyfluorinated trialkoxysilane, and an organometallic cure catalyst. A coating on a substrate is provided that includes a cured film produced by the cure of the coating composition. The coating has a contact angle of at least 93 degrees after 500 hours of exposure to UV-A exposure in ASTM D 4329 QUV using UVA 340 bulbs, cycle B exposure of alternate cycles of UV exposure and condensing humidity all at elevated temperature.
