SPREADING PASTES CONTAINING POLYURETHANE PLASTICS AND A PROCESS FOR THE PRODUCTION OF POLYURETHANE COATINGS PERMEABLE TO WATER VAPOR

摘要

SPREADING PASTES CONTAINING POLYURETHANE PLASTICS AND A PROCESS FOR THE PRODUCTION OF POLYURETHANE COATINGS PERMEABLE TO WATER VAPOR This invention relates to spreading pastes containing polyurethanes which are prepared from special synthesis components selected from the group of silicone resins, polyethers or polyesters containing aromatic segments or perfluorocarbon resins. The spreading pastes also contain organic solvents and optionally non-solvents for the polyurethanes so that when the coatings are used to coat textile substrates according to the direct or transfer process, the coatings may be cured based on the principle of evaporation coagulation.
