ADHESIVE COMPOSITION Russian patent published in 1999 - IPC

FIELD: adhesive melt in anticorrosive and protective coatings for gas, water and oil pipelines. SUBSTANCE: adhesive composition comprises, wt %: ethylene-vinyl acetate copolymer, 62-90; talc, 1-10; γ-aminopropyl triethoxysilane, 1-5; resin, 5-20; and mica, 1-3. Composition also comprises mineral fillers such as talc and mica for strengthening interaction of polymeric matrix with metals and plastic materials having low surface energy due to formation of additional hydrogen bonds. EFFECT: higher shear strain when adhesive joint between metal and plastic material having low surface energy breaks up, lower percentage of natural resins in adhesive composition.
