Abstract RU 2698661 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a moisture-curable hot-melt adhesive composition containing from 50 to 95 wt. % of reaction product (i) of semi-crystalline polyol, (ii) polyisocyanate and (iii) primary aminosilane; and from 5 to 50 wt. % silane-reactive plasticiser, as well as a method for production thereof and use.

EFFECT: silane-reactive hot-melt composition according to the invention is characterized by absence of isocyanate monomers, provides good adhesion to various substrates, fast setting and high strength in cross-linked state.
