POLYMERIC COMPOSITION OF COLD SOLIDIFICATION FOR WATER PROOF COATINGS Russian patent published in 1995 - IPC

FIELD: corrosion resistance. SUBSTANCE: composition comprises 70 - 200 parts of polybutyl methacrylate, 100 - 350 parts of methyl methacrylate, 5 - 245 parts of butyl methacrylate, 20 - 45 parts of product from interaction between allyl alcohol and toluylene diisocyanate, 1 - 8 parts of dimethyl aniline, 5 - 15 parts of benzoil peroxide, 10 - 800 parts of activated basalt scale. Dimethylamine is added to mixture of methyl methacrylate, butyl methacrylate and polybutyl methacrylate, then product of interaction between allyl alcohol and toluylene diisocyanate, activated basalt scale are added and mixed. Brush or putty knife are used to apply the solution. Time of complete solidification is 10 days. EFFECT: 12.8 - 17.9 MPa adhesion strength in 6 months in 30 per cent solution of NaOH, and 8.5 - 20.1 MPa in 6 months in 60 per cent solution of H₂SO₄. 2 tbl
