METHOD OF ISOLATION OF STRUCTURE MEMBER IN CORROSION MEDIA Russian patent published in 1997 - IPC

FIELD: polymeric composition. SUBSTANCE: method involves applying three layers at 15-30 min interval between each layer of polymeric composition that has, p. p.: methylmethacrylate 100; polybutylmethacrylate 10-70; butylmethacrylate 5-60; polyisocyanate 10-40; dimethylaniline 0.05-2.00; divinylbenzene 0.1-10; benzoyl peroxide 0.1-10.0; perchlorovinyl resin 0.5-25.0; diethanolamine maleinate 0.01-0.50, and amine 0.01-1.00. For median layer composition has additionally silicon carbide. Coating hardening time is 3-4 h, complete hardening - for 10 days. Composition is used for cathode protection in electrolysis bath for pure metal producing. EFFECT: improved method of isolation. 2 tbl
