ORCO PU Reactive Polymeric Colorants are specifically designed for polyurethane (PU), used in various applications such as foam, elastomers, adhesives and synthetic leather. Unlike traditional PU Pigment Dispersions, ORCO PU Reactive Polymeric Colorants will react into the PU Polymer Matrix directly, providing strong color fastness and solvent resistance.
ORCO PU Reactive Polymeric Colorants are manufactured through a green production process, without using any harmful solvents such as Dimethylformamide (DMF).
High Color Strength
-
- 3-5 times stronger color strength than conventional PU paste
Superior Color Fastness
-
- Strong chemical bonding formed by hydroxyl groups (-OH) reacting with isocyanate groups (-NCO) in polyurethane
- Exceptional color fastness and solvent resistance, non-migrating and non-extractable
Excellent Compatibility
-
- Highly compatible with both polyester and polyether urethane systems
Easy to Blend
-
- Can be blended to achieve custom shades
Easy to Handle
-
- Low Viscosity and coagulation
- Easily pumped at room temperature
Easy to Use
- Water Soluble and easy to clean up
- Can be used to color PU in-line with foaming process, and short color change out
