METHOD FOR PRODUCTION OF FIREPROOF COATINGS Russian patent published in 1995 - IPC

FIELD: fireproof coatings. SUBSTANCE: heat insulating layers of composition which contains 30-60 of siloxane rubber and 40-70 of glass microspheres are applied on surface. Then fireproof layers of composition which contains 20.0-79.5 of siloxane rubber, 20.0-60.0 of glass microspheres and 0.5-20.0 of boron nitride is applied on said surface. Each layer is dried at 20-80 C, final heat treatment is carried out at 80-150 C, summary thickness of mentioned above fireproof layers being not more 3 mm. Rate of destruction thus prepared coating at 1000 c is 0.15-0.55 mm/s, its deformation being 8-12 EFFECT: improves efficiency of the method. 2 tbl
