Title:
HYDROPHOBIC PERMANENT COATINGS ON SUBSTRATES AND METHODS FOR PRODUCTION THEREOF
Document Type and Number:
WIPO Patent Application WO2002087784
Kind Code:
A3
Abstract:
The invention relates to the field of chemistry and coatings, which can be used for example in the production of painted coatings and a method for production thereof. The aim of the invention is to describe coatings with hydrophobic to ultra-hydrophobic properties. Said aim is achieved by means of hydrophobic permanent coatings made from a cross-linked layer of a hardener component (A) and a resin component (B), whereby (A) and/or (B) comprise chemically coupled, lateral and/or terminal perfluoroalkyl groups with at least one trifluoromethyl end group, with a coupling between the layer and the surface region of the substrate. Said aim is further achieved by means of a method, in which the coating agent, containing perfluoroalkyl groups, is applied to a surface in the form of a melt, powder, dispersion or solution, a film formation with addition of energy, with or without a partial cross-linking and at least one partial coupling and then, again with introduction of energy, a complete cross-linking of the layer is carried out.
