FIELD: adhesives.
SUBSTANCE: invention relates to ethylene copolymers-based adhesive compositions used as adhesives when depositing polymeric protective coating on metallic surface utilizing extrusion and co-extrusion techniques and winding thermosetting multiple-layer adhesive tape. Using composition containing ethylene/vinyl acetate copolymer, silicate filler, and modifying agent (resin OSR-100) results in providing preservation of high adhesion and strength characteristics and resistance to cathode peeling when lowering metal temperature heating to 100-130°C in double-layer coating structure and also ensuring high values of adhesion strength for ground epoxide layer in triple-layer coating structure.
EFFECT: enhanced adhesive properties in multiple-layer coating applications.
