Surface Studies of Glass. Part I. Contact Angles

Abstract
The water‐repellent nature of glass surfaces treated with different silicones is examined by means of contact‐angle measurements. Results are given showing the effect of various concentrations of silicones, types of glass, temperature of heat treatment, length of time of heat treatment, and surface roughness on the water contact angles. Silicones containing the methyl and phenyl group show good heat stability at temperatures of 500°C for short periods of time.
