Abstract: An asphalt blend in which a butadiene-styrene elastomeric block polymer can easily be dispersed at between about 325.degree. F. and about 400.degree. F. and, after cooling, forms a stable material useful as a roofing composition and having a flash point of greater than about 450.degree. F., said blend being composed of a propane extracted asphalt and from about 5 weight % to about 45 weight % of a fluid bed catalytic petroleum cracker bottoms oil comprising a major proportion of oils boiling above 700.degree. F. and, optionally, a minor proportion of oils between about 350.degree. F. and 700.degree. F.

Abstract: A composition especially useful as a primer coating having improved hot line adhesion and cathodic disbonding resistance comprises a solution of chlorinated rubber and aromatic petroleum pitch in a solvent.

Abstract: Disclosed are: (1) A primer coating composition containing an air-blown, solvent extracted asphalt having a penetration of about 1 to about 12 and a softening point of about 150.degree. to about 270.degree. F; (2) a blend of 70-92 parts by weight of an air-blown, solvent extracted asphalt having a penetration of about 0 to about 7, and a softening point of about 200.degree. to about 250.degree. F., and about 8 to about 30 parts by weight of a non-air-blown, solvent extracted asphalt having a penetration of about 40 to about 150, and a softening point of about 105.degree. to about 130.degree. F., the blend having a ductility at 77.degree. F., using a speed of one cm per minute of at least 2.5, a penetration of about 7 to about 15, and a softening point of about 200.degree. to about 220.degree. F.; (3) metallic substrates coated with the primer composition set forth above; and (4) metallic substrates having a coating containing the blend set forth above.

Abstract: A composition, especially useful for making coating compositions, and having unusually good properties, comprises at least one solvent extracted hard asphalt, at least one polyhydroxy polymer, and, optionally, at least one filler and at least one stable, non-volatile, tertiary amine catalyst. This composition, where combined with at least one polyisocyanate, forms a composition especially useful for coatings, particularly finish coatings.

Abstract: A precursor composition, especially useful for making a patching and coating composition, and having unusual physical properties, comprises at least one non-air-blown, solvent extracted asphalt, at least one polyhydroxy polymer, at least one polyhydroxy compound, at least one polyamine, at least one solvent, and, optionally, at least one filler. This precursor composition, where combined with at least one polyisocyanate, forms a composition especially useful for coating and for patching coating.
