FIELD: chemistry.
SUBSTANCE: invention refers to emulsion water-repellent dedusters for composites as follows: synthetic resins as binding and fibrous inorganic reinforcing agent for manufacturing heat- and sound-insulating structural members. The water-repellent deduster contains mineral oil of flash temperature not less 260°C, silicone fluid of viscosity 150 to 400 cCt at 25°C, non-ionic and/or anionic emulsifier, biocide, adhesive and water. Oil-silicon emulsion ensures hydrophobic properties of composites and finished products (quills, panels and plates) thus considerably reducing dust separation in work.
EFFECT: hydrophobic properties of composites and reduced dust separation in work.
