ACIDPROOF POLYMER COMPOSITION FOR COATINGS Russian patent published in 1995 - IPC

FIELD: protection against corrosion. SUBSTANCE: proposed composition contains (mass parts): polybutyl methacrylate 70-200, methyl metacrylate 105-375, polyisocyanate 5-50, perchlorovinyl resin 1.5-40, benzoyl peroxide 5-15, dimethyl aniline 1-8, activated basalt scale 10-800, chromium oxide 10-200. Polybutyl methacrylate is mixed with polychlorovinyl resin, thus prepared mixture is dissolved in methyl methacrylate at room temperature. Then polyisocyanate is added into mixture and other mentioned above ingredients are also added by mixing. Thus prepared composition is applied on metal surfaces with the help of brush or spatula. Coefficient of heat conductivity desired coating is 0.193-0.41 W/m K, its adhesive strength on open air within 10 days is 18.8-16.4 MPa. EFFECT: improves quality of desired coating. 2 tbl
