FIELD: sealing of building units, coating of metals. SUBSTANCE: proposed composition contains (mass parts); polybutadiene-urethane prepolymer 100, liquid bitumen 100-80, filler 2.5-5. Product of interaction of toluylene diisocyanate with polytetrafuran diol having molecular weight 1000-2000 and/or with polybutylene glycol adipinate having molecular weight 1500-2060 is used as mentioned above polybutadiene-urethane polymer. Powder minerals (e.g. cement, gypsum, chalk, kaolin) are used as said filler. Hardening time of proposed composition is about 2 h. EFFECT: improves quality of desired product. |
