Use of Isocyanates in the production of highly viscous self-sticking compositions

摘要

Hot-melt adhesives (I) comprises: (A) 100 parts by weight (pts. wt.) non-thermoplastic elastomer(s); (B) 1-200 pts. wt. tackifying resin; and (C) unblocked polyfunctional isocyanates in amounts corresponding to 8-5000 mmols reactive isocyanate groups per kg of (A). Independent claims are also included for: (a) self-adhesive articles obtained by applying (I) to at least one side of a strip of base material; (b) a method for the production of self-adhesive articles, especially high-performance articles such as tape or labels, by coating (I) onto a suitable base using a multi-roll coating system with 2-5 rollers.
