Requirements for Polyurethane Dispersions as Primary Resins in Color Paste Formulation

Polyurethane dispersions (PUDs) for pigment dispersion must achieve ‌ultra-fine particle size control‌ to ensure colloidal stability and chromatic uniformity, supported by ‌electrostatic/steric stabilization‌ for pH tolerance and thermal resistance. The resin requires ‌broad solvent compatibility‌ with polar/non-polar blends (e.g., alcohols, ketones) to maintain viscosity stability and storage durability. ‌Low ionic content‌ prevents pigment flocculation in aqueous systems, while ‌APEO-free‌ and ‌REACH-compliant‌ formulations address eco-regulatory demands. Optimal storage conditions (5–35°C) and frost protection are critical to preserve dispersion integrity. For application versatility, ‌shear-thinning behavior‌ balances high pigment loading with spray/brush adaptability, complemented by adhesion performance for substrate bonding. Modified ionic architectures (anionic/non-ionic) enhance electrolyte resistance and cross-linking flexibility

Product Introduction
WL-PU212 is an aliphatic waterborne polyurethane dispersion with low viscosity, high elasticity, and good resistance to yellowing, suitable as the main resin for color paste dispersion.
