Milliken Colorants Polyurethane Reactive Dyes Reactint Colorants
Milliken Reactint Reactive Polyurethane Colorants Reactint reactive colorants are a technology developed by Milliken Chemical for use in polyurethanes and other thermosetting resins. Unlike traditional pre-dispersed pigment pastes, Reactint is a reactive polymer colorant that is chemically incorporated into the polyurethane structure. It is a homogeneous liquid, stable in storage, low in viscosity, soluble in water and polyhydroxy resins, and does not precipitate. Therefore, Reactint reactive colorants can be dynamically mixed in-line during the production of polyurethane foams and resins.

Reactint is one of the most popular polyurethane coloring systems used. It is used in polyurethane sponges, elastomers, adhesives, coatings, synthetic leathers, bowling balls and other polyurethane products that require high color quality. It is simple to color match and can easily provide any color to customers using only five Reactint primary colors.

Reactint offers the following advantages.

Quality

①, much higher color depth than conventional pigments, no color loss

②, less color marks, no cracks or pinholes

③、No heavy metal, no coking

④、High migration resistance and solvent resistance

⑤、Does not affect the foaming performance of sponge

Simple process

①、No layering, no need to stir

②、Low viscosity, can be pumped at room temperature

③、No particle formation, will not block the pipe

④、Five primary colors can provide all color requirements

⑤、Applicable to polyether and polyester sponge, carbon dioxide foaming system

⑥、Soluble in water, easy to clean

Low cost

①、Reduce the defective products, do not affect the polyurethane formula, can reduce the flow marks, pinholes and sponge cracks

②、Reduce the inventory, high luminous intensity, the inventory is reduced accordingly, only five kinds of primary colors need to be stocked, instead of hundreds of customer’s pigments

③, reduce scrap, easy to disperse in butter, change color quickly and save time to reduce scrap

④、Improve production efficiency, stable quality of reaction dyes, easy to clean

⑤、High luminous intensity, the luminous intensity of reaction dyes is 3-5 times higher than general pigments.
