BYK W 9011 is a wetting and dispersion additive that improves the properties of filled formulations. BYK W 9011 reduces viscosity enabling higher filler loading while improving homogeneity and batch reproducibility. It is solvent-free and recommended where solvents need to be avoided. BYK W 9011 improves the wetting and dispersion of common fillers like calcium carbonate and aluminum hydroxide. This results in a more consistent quality and allows formulations to meet requirements. BYK W 9011 is suitable for use in low emission systems and provides a cost-effective alternative to similar products. It can be added during the initial mixing stage and provides benefits throughout the manufacturing process and final application.
