FIELD: chemistry.
SUBSTANCE: invention refers to coated fibre reinforced products. Method for lowering the quantity of siloxane dust forming in oven includes obtaining gypsum suspension by burning under pressure, introduction of siloxane dispersion in above suspension after burning stage, removal of water from the suspension with formation of filtering residue, desired shaping of the residue, providing the possible setting with product formation, applying coating on the product containing alkali metal organic siliconate, placing the coated product into oven.
EFFECT: increased water-resistance, lowered siloxane evaporation during drying.
