What is Reactint®?
Reactint colorants are not pigment pastes or dyes. They are reactive polymeric colorants consisting of chromophores which are chemically bound to polyols. Unlike pigment pastes, which are dispersions of solid particles in a liquid carrier, Reactint colorants are 100% homogeneous liquids. They are soluble in polyol and will not settle over time.
Reactint polymeric colorants become part of the urethane resin matrix. They are not solid particles and will not nucleate or cause voids, and they have little or no effect on catalyst loading or foam formation.
