KR940014218A - Composition of room temperature curing type water and oil repellent - Google Patents

Abstract

The present invention relates to a composition of a room-temperature-curable water- and oil-repellent agent that imparts water repellency, abrasion resistance, and fouling resistance to glass of automobiles, ships, aircraft, and buildings, and includes functional groups and water-repellents that can react with silanol groups on the glass surface, It is composed of one or two or more of the compounds having a functional group showing oil repellency and components that can be cured at room temperature and promote chemical reaction with the glass surface. It can be easily applied to the existing structure or existing glass manufacturing process because the heat treatment process is not necessary, and can overcome the limitation of the use range.
