Thermal Insulation System for Buildings and for Liquid Storage and Transportation

Abstract

Insulating compositions in the form of aqueous dispersions which comprise hollow borosilicate glass spheres or ceramic microspheres, wax encapsulated thermoset particles and spherical thermoplastic microspheres and an emulsion polymer or redispersible powder binder. The compositions may applied as a primer or top coat in interior and/or exterior of new and existing buildings or for the insulation of pipes, cylinders and tanks containing and transporting hot or cold liquids or low boiling point liquids.

         8 . An insulating composition according to  claim 1 , wherein the amount of emulsion polymer or re-dispersible powder binder is 10-30%. 
     
     
         9 . An insulating composition according to  claim 1 , wherein the amount of emulsion polymer or re-dispersible powder binder is 12-25%. 
     
     
         10 . Use of an insulating composition of  claim 1 , for the preparation of an insulating paste, panel, board, paint or plaster. 
     
     
         11 . An insulating paste, panel, board, paint or plaster prepared from the composition of  claim 1 .
