FIELD: chemistry of polyurethane foam. SUBSTANCE: oxyalkylene organosiloxane block copolymer is proposed as organosilicon foam adjuster, mixture of 1,4-diazobicyclo(2,2,)-octane with dimethylethanol amine is used as nitrogen-containing catalyst. Quantity of proposed ingredients is within definite ranges. Thus obtained desired component retains its viscosity. EFFECT: improves efficiency of the method. |
