Reactint colorants, the most widely used coloring system in the world, are a proprietary technology developed by Milliken Chemical for coloring polyurethane and other thermoset resins for over 25 years.

Reactint Colorants are reactive polymeric colorants that consist of Chromophore which are chemically bound to polyols. This allows the Reactint Colorant to react into the polyurethane polymer matrix.
