VP 6272 Waterborne colour paste dispersant

Name: VP 6272 Waterborne colour paste dispersant - Vortex
SKU: 6272

The 6272 Waterborne Colour Paste Dispersant represents a high-performance, non-ionic polymeric solution specifically engineered for the stabilization of inorganic and organic pigments in aqueous media. Utilizing advanced block copolymer technology, this additive functions by anchoring firmly onto pigment surfaces while providing exceptional steric stabilization through its extended polymer chains. This dual-action mechanism prevents flocculation and sedimentation, ensuring long-term shelf stability of highly concentrated colorants. As a solvent-free and APEO-free formulation, 6272 aligns with modern environmental standards, making it an ideal choice for low-VOC coating systems. It significantly reduces the millbase viscosity, allowing for higher pigment loading and improved grinding efficiency. Furthermore, it enhances the aesthetic properties of the final film, providing superior gloss, transparency, and color development. Whether employed in architectural paints or industrial inks, 6272 serves as a critical component in achieving uniform dispersion and consistent coloristic performance across diverse water-based resin systems and substrate types today.
