摘要

Adhesive composition, use, polyurethane pre adhered, adhesive system, process to become a polyurethane cured at a composition of elastu00c8mero diu00eanico in uncured state, composite, use of the same and article of rubber adhesive composition usable notably with The first coat of accession,Based on a poliisocianato compound and a polyester resin or vinylester comprising functional groups (notably hydroxyl) reactive isocyanate groups of the front poliisocianato, the total number of such groups, isocyanate being in excess compared to the total number of These functional groups of the polyester or vinylester resin.The compound poliisocianato is preferably a diisocyanate, the resin is preferably a resin epoxivinilu00e9ster, mainly based novolaca and / or biphenolic.This composition is usable, the title of the first coat of accession, in combination with a second coat of accession, preferably based on a polivinilpiridina styrene butadiene elastomer and a polyester or vinylester resin.Use of an adhesive system for the connection of a cured polyurethane elastomer composition diu00eanico in uncured state, especially in the manufacture of rubber consisting of systems of connection to the ground of automotive vehicles, particularly the bands of wheel Gem pneumatic or pneumatic.
