Abstract
Protective coating solutions for cementitious substrates are disclosed which comprise a minor amount of a cyclohexane based organic solvent on a major amount of an asphaltic material. The asphaltic material is a blend of asphalt with the reaction product of asphalt, a vinyl aromatic monomer, a rubber and an unpolymerized acrylamide.
Claims14
An environmentally acceptable protective coating solution having good shelf life, said solution comprising a major amount of an asphaltic material and a minor, but effective solvating amount of a cyclohexane based solvent, said solvent being an admixture of at least about 75% (wt) cyclohexane, 15%-25% toluene and up to 10% n-hexane, said asphaltic composition being a blend of a minor amount of asphalt having a viscosity of less than about 120,000 cps (at 140.degree. F.), and a major amount of the product produced by reacting a vinyl aromatic monomer, asphalt having a viscosity of less than 120,000 cps (at 140.degree. F.), a rubbery polymer and an acrylamide.
