ABRASION- RESISTANT COATING COMPOSITION PREPARED BY HYDROLYSIS OF ORGANIC-SILICATES AND SILANES

摘要

A coating composition prepared by simultaneously hydrolyzing 20 to 50 wt. % tetraethylorthosilicate, 37 to 60 wt. % of certain silanes and 15 to 35 wt. % formalin has good abrasion resistance and resistance to crazing on substrates having a high affinity for water as well as those with a low affinity for water.
