CMC · Paints & coatings
Coating-Grade CMC
Thickener and water-retention agent for emulsion paints, putties and adhesives.
[01]Overview
Sentai coating-grade CMC thickens water-based emulsion paints, improves brushability and levelling, prevents pigment settling and retains water in putties and texture coatings so they cure without cracking. An instant variant disperses directly in the grind.
