COMPOSITION FOR ANTICORROSIVE COATING Russian patent published in 1994 - IPC

FIELD: protective fluoroplastic coating production. SUBSTANCE: composition contains, % : soluble copolymer of trifluorochlorethylene and vinyl idenefluoride having molecular weight 5·10⁴-1,6·10⁵ 7-14, fluororubber on the base of trifluorochlorethylene and vinylidenefluoride copolymer having molecular weight (1.5-2.5)(1,5-2,5)·10⁵ 0.04-0.07, aminoalkoxysilane 0.02-0.2, 2,2,4-trimethyl-6-ethoxy-1,2-dihydroquinoline 0.01-0.05, cyclohexanon 0.02-0.2, mixture of acetone and butylacetate at ratio 1: 1 the rest. Mixture of acetone and butylacetate is fed into tank having mixer. Power of fluoronone and fluororubber is added by mixing. Solution of aminoalkoxysilane in cyclohexanon and 2,2,4-trimethyl-6-ethoxy-1,2-dihydroquinoline are added after dissolution. Thus prepared composition has: impact strength 5 J, strength after sustaining within 7 days in 30% HCL at 20 C is 5 J, stability in steam of 30% HCl at 90 C is 700 h. EFFECT: improves composition quality. 2 tbl
