VP 6270A Waterborne colour paste dispersant

Name: VP 6270A Waterborne colour paste dispersant - Vortex
SKU: 6270A

The 6270A Waterborne Dispersant is a high-performance, non-ionic block copolymer designed specifically for the stabilization of organic pigments and carbon black in aqueous systems. As a critical additive in the formulation of high-quality color pastes, 6270A facilitates the efficient wetting and de-agglomeration of pigment particles during the grinding process. By providing robust steric stabilization, it prevents the re-flocculation of dispersed particles, ensuring long-term shelf stability and uniform color development. This additive is particularly effective in resin-free pigment concentrates, where it significantly reduces millbase viscosity, allowing for higher pigment loading without compromising flow properties. Furthermore, 6270A enhances the gloss and transparency of the final coating film while minimizing common defects such as flooding, floating, and syneresis. Its versatile chemical structure makes it compatible with a wide range of waterborne binders, including acrylics, epoxies, and polyurethanes, making it an indispensable tool for achieving superior coloristic properties in modern high-performance industrial aqueous coatings.

Attributes

Key Features and Benefits
