Dispersing Agent for Paint: Selection & Trial Guide
A dispersing agent for paint must help the pigment remain dispersed in the actual binder and liquid phase after grinding and let-down. Shortlist it from the formulation and the failure being corrected: poor color development, flocculation, excessive mill-base resistance to flow or storage instability. A waterborne label or a matching trade-name description is not sufficient evidence of compatibility.
