Filled polyol mixture, useful for the production of surface coatings, adhesives and multi-layer molded articles, comprises a difunctional or a trifunctional polyether polyol and a particulate filler.

摘要

A filled polyol mixture (I) comprises (A) a difunctional polyether polyol (A1) and a trifunctional polyether polyol (A2) and (B) at least 25 wt.% of a particulate filler having a particle size of 60-100 microns. Independent claims are also included for: (i) a two component reactive resin system (II) comprising the polyol mixture (I) and at least one compound containing two groups that are reactive with OH groups; (ii) a laminated molded article (III) comprising at least 3 layers, whereby the second layer is prepared using (I) or (II); and (iii) a process for the production of a laminated article (III) by edge sealing a first molded article forming the first layer and a second molded article forming the third layer such that a 0.1-100 mm high cavity is formed between them having at least 2 openings whereby the reactive resin system (II) is injected via the first opening into the cavity to fill it.
