CRAYVALLAC® A-2678-M

CRAYVALLAC® A-2678-M is a high-performance acrylic dispersing and flow control agent for the control of coating surface properties. It was developed specifically to eliminate film surface defects that may occur during the film formation. The following benefits are to be gained by using CRAYVALLAC® A-2678-M in water-based coatings:  enhanced substrate wetting and coating levelling, reduced craters, fisheyes and pinholes. The results of these enhancements are smoother films with fewer imperfections and a superior overall appearance (measurable with glow and DOI) when compared with the unmodified coating.
