  • Pressure resistant and heat-stable insulating coatings for hollow bodies, and a method for producing the same
    Patent number: 6387447
    Abstract: A process for the production of insulating coatings containing polyurethane groups and/or polyisocyanurate groups for hollow bodies by reaction of a) a polyisocyanate component with b) compounds which contain at least two hydrogen atoms which are active towards isocyanates and c) catalysts, optionally in the presence of d) further auxiliary substances and additives, characterised in that 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 are added to at least one of components a) to d), is described. The use of these insulating coatings for pipes employed in the offshore sector is furthermore described.
