Title:
PROCESS FOR COATING TO OBTAIN SPECIAL SURFACE EFFECTS
Document Type and Number:
WIPO Patent Application WO2004003281
Kind Code:
A3
Abstract:
A process for coating substrates to produce surfaces which have a textile-like texture; the process comprises the following steps: a) coating fibers with a polymer dispersion based on one or more polymers selected from the group of polyurethanes, polyester polyurethanes, polyesters or mixtures thereof, b) blending the coated fibers together with the polymer dispersion to form a coating material and applying the coating material onto the surface to be coated and c) curing the coating material thereby forming a coating on the surface of the substrate; also, the process according to the invention relates to a coating material which is applied onto the substrate surface, comprising A) 5 to 40 wt. % of the polymer dispersion basing on one or more polymers selected from the group polyurethane, polyester polyurethane and polyester, having a solids content of 25 to 90 wt. %, B) 0 to 35 wt. % of one or more cross-linking agents, selected from the group of formaldehyde condensation resins and polyisocyanates, C) 2 to 20 wt. % of fiber material, D) 0 to 20 wt. % of solvent, E) 5 to 35 wt. % of water, and optionally, F) 0.5 to 10 wt. % of additives conventionally used in connection with coatings, pigments and/or extenders.
