Abstract:
A process for the production of an insulating coating containing polyurethane groups and/or polyisocyanurate groups for a hollow body which has a heat distortion point above 120Â° C. and a compressive strength above 50 bar comprising applying to the hollow body a reaction mixture comprisinga) a polyisocyanate component with b) a compound which contains at least two hydrogen atoms which are active towards isocyanates and c) a catalyst, optionally in the presence of d) an auxiliary substance or additive, in amounts such that an isocyanate index of from 90 to 2,000 is achieved in which mixture organic or mineral hollow microbeads having an average particle size in the range from 5 to 200 &mgr;m and a density in the range from 0.1 to 0.8 g/cm3 had been added to at least one of components a), b), c) or d).
