Reactint®
Product Description
Reactint colorants are Milliken’s proprietary reactive polymeric color solutions designed specifically for polyurethane and other thermoset resin applications. Unlike traditional pigment pastes, Reactint colorants are 100% homogeneous, polyol‑soluble liquids that will not settle, separate, or cause defects such as voids or streaking. During curing, Reactint colorants chemically react into the polyurethane polymer network, forming a fully integrated, non‑extractable color matrix. This enables deep and bright shades and high color strength at low loadings. Manufacturers benefit from reduced inventory, easy pumping and metering, faster color changeovers, and improved equipment life due to the non‑abrasive composition.
Reactint colorants enable manufacturers elevate polyurethane product performance, aesthetics, and production efficiency while lowering cost. Backed by Milliken’s color expertise and collaborative support, manufacturers gain access to precise color matching, faster development cycles, and solutions tailored to their specific applications.
By chemically integrating color into the polymer matrix, Reactint delivers unmatched color consistency, long‑term stability, and superior mechanical integrity compared to pigment‑based systems. Manufacturers reduce inventory, eliminate settling issues, minimize waste, and streamline operations, while end‑users benefit from bright, stable colors that do not migrate or fade.
