COMPOSITIONS FOR FORMING WATERPROOFING COATINGS Russian patent published in 2003 - IPC

FIELD: waterproofing materials. SUBSTANCE: composition suitable for waterproofing protection of building materials (ferroconcrete, brick, roofing slate, wood, etc. ) consists of polyacrylate or butadiene/styrene latexes, epoxide 4,4'- isopropylidenediphenol resin, emulsifier: polyvinyl alcohol, filler: titanium dioxide or zinc dioxide, hardener: polyethylenepolyamine, and water as diluent. Compositions are non-inflammable, blastproof and are characterized by high adhesion to building materials, low water absorption, and high spreading capacity, which is the reason for that composition can be recommended as waterproofing and painting material for steel units. Addition of various pigments allows manufacturing coatings with wide spectrum of colors. EFFECT: expanded possibilities of forming high-quality waterproofing coatings. 1 tbl, 8 ex
