Abstract

Organosilicon compounds used for production of hydrophilic surfaces are prepared via an addition reaction of epoxy-functional silanes onto polyethylene glycols, cross-linked via a condensation reaction, and used for modification of substrate surfaces such as hardened silicone elastomers, glass surfaces, surfaces of silicatic construction materials, metals, and plastics.

Description

Technical field [0001] The present invention relates to organosilicon compounds, methods for the production of these compounds, and the use of these compounds in the production of hydrophilic surfaces, and preferably relates to compositions and preparations that contain the compounds or have been coated with the compounds , And materials. Background technique [0002] The production of hydrophilic surfaces is expected in many sectors. In the case of building materials and building aids, in order to reduce droplet formation, a hydrophilic surface may be desirable for faster outflow (runoff) and condensation of water, thereby for faster drying, and to avoid scale deposits And avoid residues from water. The hydrophilic surface prevents fogging of optical components, glasses, and windows. In the case of silicone, the hydrophilic surface can delay the adhesion of microbial flora and salt deposits (salt beds), and the contamination of organic matter. The hydrophilic surface improve...
