FIELD: metallurgy.
SUBSTANCE: invention concerns foundry field. Particularly it is used at production of founding form cast steel and steel. Covering contains, mass %: refractory filler 53.0 - 58.0; water 22.0 - 24.0; lignosulphonate 17.5 - 19.5 and organosilicon oligomer, allowing in the capacity of functional aggregation hydrosilane groups, 2.5 - 3.5. In the capacity of organosilicon oligomer compound contains 1,1-dimethyl-silicopropane-3-ol of the following formula: (CH3)2SiH-SiH2-SiH2OH). Adding of 1,1-dimethyl- silicopropane-3-ol leads to hardening and heat resistance increasing of antipenetration wash.
EFFECT: hardening and heat resistance increasing of antipenetration wash.
