Polyurea was modified by glass microspheres. Compositions of polyurea coatings based on glass microspheres were obtained. The properties of the coatings were evaluated. The results of studies of polyurea-based coating compositions containing hollow glass microspheres are reported. Similar coatings are proposed for waterproofing pre-insulated heat pipes. The composition of a polyurea-based coating containing hollow glass or aluminum-silicate microspheres with diameter 200 – 300 μm and a range of functional additives including ammonium polyphosphate, wollastonite, and microcalcite in a 1 : 1 ratio of glass to aluminum-silicate microspheres was investigated.
