ADHESION COMPOSITION Russian patent published in 2004 - IPC

FIELD: adhesion compositions.

SUBSTANCE: invention relates to adhesion compositions used in anti-corrosion and protective covers for gas, water and petroleum pipelines, heat pipelines as glue-melt. The composition comprises the following components, wt.-%: copolymer of ethylene with vinyl acetate, 80-93; γ-aminopropyltriethoxysilane, 0.5-3; colophony, 5-10; peroxide, 0.5-4; difurfurylidene acetone 0.5-3. Use of peroxide and difurfurylidene acetone for enhancing cohesion and adhesion strength allows using glue junction at higher loadings and exploitation temperatures and without elevating temperature of preliminary heating materials to be glued.

EFFECT: improved, enhanced and valuable properties of composition.
