Modification of polyurea with glass microspheres has been carried out. Polyurea compositions of coatings based on them have been obtained. Their properties are assessed. The results of studying the compositions of coatings based on polyurea containing hollow glass microspheres are presented. It is proposed to use such coatings as waterproofing for pre-insulated heat supply pipes. The composition of a coating based on polyurea, containing hollow glass or aluminosilicate microspheres with a diameter of 200 - 300 ?m, functional additives selected from the series, including ammonium polyphosphate, wollastonite, microcalcite with a ratio of glass and aluminosilicate microspheres of 1: 1, was investigated.
