EPOXY COMPOSITION Russian patent published in 1995 - IPC

Abstract RU 2039773 C1

FIELD: preparation of water resistance coatings. SUBSTANCE: the epoxy composition comprises 100 g of an epoxy diane oligomer; 74.8-173 g of a cetimine hardener modified with an urethane containing isocyanate and 1-2 g tris (dimethyl aminomethyl) phenol. The hardener has the general formula: wherein N is C-C6H4 and R is H or , m is 1 or 2, n is 2 or 3 if m is 1, then R is other than H and if m is 2, then one of R is NHCOOCH2(CF2CF2)nH with a molecular weight of 700-1300. The composition is prepared by mixing components and is applied onto a metal or glass plate and allow it to solidify at 20 C for 10 days or at 120 C for 3 hours. Composition based compositions have improved water resistance, adhesion properties and heat resistance. EFFECT: improved properties of the epoxy composition. 6 tbl
