Abstract

PURPOSE: To provide the titled compsn. having excellent water resistance, etc. and suitable for use in undercoating concrete during the waterproofing treatment of concrete, by blending a bituminous material and a solvent with an isocyanate group-contg. urethane prepolymer having polydiene chains in the molecule.
CONSTITUTION: A liquid active hydrogen group-contg. polymer such as polybutadiene homopolymer or polyisoprene homopolymer is reacted with an org. polyisocyanate compd. such as tolylene diisocyanate to produce an isocyanate group-contg. urethane prepolymer having polydiene chains in the molecule. Then 50W900pts.wt. bituminous material such as straight asphalt and 20W300pts.wt. (per 100pts.wt. of the combined amount of the above urethane prepolymer and the bituminous material) solvent such as acetone are added to 100pts.wt. said urethane prepolymer.
