Product overview
CRAYVALLAC® A-2678-M is a high performance acrylic dispersing and flow control agent for the control of coating surface properties. CRAYVALLAC® A-2678-M has been 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 pinhole. 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.
