Water-soluble surface treating agents

摘要

A surface treating agent comprising a reaction product of (A) a fluoroalkyl group-containing alkoxysilane with (B) an amino group-containing alkoxysilane and optionally further with (C) an alkyl group-containing alkoxysilane is water soluble. The agent is diluted with water to form a solution for treating glass and other substrates to impart durable water repellency and other improved properties to the substrates.
