ADHESIVE COMPOSITION BASED ON ETHYLENE AND VINYL ACETATE COPOLYMER Russian patent published in 2021 - IPC C09J123/08 

FIELD: adhesive materials.

SUBSTANCE: invention relates to adhesive compositions used as an adhesive underlayer (primer) when applying anticorrosion and protective coatings on metal surfaces, as well as adhesives-melts, sealants in other industries. Composition contains, wt %: copolymer of ethylene with vinyl acetate 78–93.5; γ-aminopropyltriethoxysilane 0.5–3; colophony 2–5; N,N'-bis-n-nitrosophenylderivative of alkane-diamine, such as 1,2-ethanediamine or 1,6-hexanediamine 3–7; mineral mica filler 1–7.

EFFECT: invention enables to obtain an adhesive composition having high cohesive and adhesion strength, thermal oxidative stability, water and alkali resistance of its adhesion bonds with a metal, resistance of these bonds to thermocyclic action.
