Compositions: coating or plastic – Coating or plastic compositions – Bituminous material or tarry residue
The addition of from about 0.1 to about 25 parts by weight of quebracho per 100 parts of bitumens (particularly asphalt), coal tar, or other high boiling tars containing mixtures of aliphatic and aromatic hydrocarbons modifies the characteristics of the treated product to enhance its performance as hot-melt adhesives, coatings, sealants, roof-coatings, and road-coatings as compared to the base bitumen. The improved characteristics obtained by the addition of quebracho include: increased softening point, lower penetration number, and higher viscosity. The quebracho may be mixed directly with the tars or put into a water solution, using sodium hydroxide if necessary, and then added to hot tars with the water being driven off.
