ADHESION COMPOSITE Russian patent published in 2002 - IPC

FIELD: adhesion composites. SUBSTANCE: invention relates to adhesion composites proposed as a primer (gluing base) for polyolephinic protective covers on metallic surfaces. The composite comprises the following components, mas. p. p.: copolymer of ethylene with vinyl acetate, 100; polyisocyanate blocked with ε-caprolactam, 1.5-3.0; stabilizing agent, 0.1-1.0; filling agent, 1-20. Invention provides the preparing a primer showing high adhesion and physical-mechanical (strength) indices and resistance against cathode exfoliation. EFFECT: improved properties of composite. 4 tbl
