Use of a polyurethane composition for the production of films

摘要

A polyurethane composition (I) for the production of films (II) comprises the following at least partially separated components: (a) a di- and/or polyisocyanate; (b) an active hydrogen containing compound for a polyurethane reaction; (c) a catalyst or catalyzing system; (d) more than 3 wt.% of a highly dispersed oxide of a metal or metalloid and; (e) optionally additives in the absence of amine initiators. Independent claims are included for: (1) a process for the production of a film (II) by spraying the composition (I) onto a flat surface at least once and allowing to react. and; (2) a polyurethane film (II) containing 5-15 wt.% of a highly dispersed oxide of a metal or metalloid.
