Abstract

PURPOSE: Titled one-pack type composition, simply handleable and excellent in adhesion and water resistance after cure, which is primarily composed of a specified asphalt pitch and a specified polyurethanepolyisocyanate.
CONSTITUTION: An asphalt pitch-urethane composition, primarily composed of (A) a composition of asphalt pitch content 10W90wt%, obtained by the addition of a solvent to an asphalt pitch of softening point 130W250°C, containing at least 10wt% of quinoline-insoluble matter, and (B) a polyurethane isocyanate polymer of average MW 200W10,000, containing 0.5W20wt% of isocyanate group, in such a proportion that weight ratio of the asphalt pitch in (A) component to (B) component is 90:10W10:90. Here a solvent, which is inert to isocyanate, and dissolved and swells asphalt pitch, for example, benzene, toluene, etc., is used for (A) component.
