Title:
COATING POLYMERIC RESIN COMPOSITION, PROCESS FOR PRODUCING THEREOF AND METHOD OF ACTIVATING THE POLYMERIC COMPOSITION
Document Type and Number:
WIPO Patent Application WO/2020/101515
Kind Code:
A3
Abstract:
The invention refers to a coating polymeric resin composition with biocidal photocatalytic properties based on resins at a ratio of 80-97 parts by weight, given the total weight of the composition, and 3-20 parts by weight, given the total weight of the composition, a photosensitizing agent based on TiO2 or ZnO oxide doped with transitional metal ions chosen from Ag, Cu, Au, Ni, Fe, Cr, Co, Mn, or combinations thereof, in which the transition metal ions represent 0.7-4.5 of the semiconductor oxide mass. The invention also discloses a photocatalytic method of activating the polymeric resin composition wherein the surface covered with the resin composition is exposed to a light source emitting at wavelengths of 450-550 nm. The invention also relates to the use of the composition of polymeric resins with biocidal photocatalytic properties for covering the surfaces of floors, walls, ceilings, products of metal accesories, solid or laminated wood, plastics, glass fibers or carbon fibers.
