Black urethane color.

The high viscosity Super Black #34-81128 paste colorant for flexible urethane foam is said to be ten times stronger than traditional carbon black colorants. The strength of the colorant is said to exceed that of dyes, making unnecessary the practice of bumping carbon black colorants with dyes to achieve intense black coloration. The high viscosity Super Black colorant is comprised of 35% to 45% pigment solids by weight (versus 10 to 12% solids for conventional carbon black colorants) and a totally reactive polyether polyol resin vehicle. Proprietary processing reduces pigment agglomerates to individual particles that are reportedly smaller and distribute more uniformly over urethane foam cells than do pigments of conventional carbon black colorants. The resulting increase in tinctorial strength and high levels of jetness attainable are said to drastically reduce letdown ratios of conventional carbon black colorants, as well as coloring costs, shipping costs and colorant inventory space.
