CRAYVALLAC® A-2678-M
Arkema Rheology & Specialty Additives
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 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.
