WBWADA-60
Water Based Wetting and Dispersing Agent
Product #120

Applications

WBWADA-60 is a unique blend of a functional capped amine with tall oil fatty acid. The resulting product is a triangular shaped wetting agent with high efficiency toward alkaline based pigments. The key to the utilization is to maintain maximum mobility of the grind paste during initial incorporation of pigment. Resin-free grinds should utilize some co-solvent if possible to improve dispersion quality. Grinding in non-neutralized resin and co-solvent at the lowest resin solids as possible, provides the most suitable grinding medium. Continue to add pigment until viscosity reaches 100-135 KU @ 100-130°F. Stabilization with neturalized resin after achieving the grind specification will help to avoid pigment shocking. The order of pigment addition should be primary colors and high oil absorption pigments followed by extenders and rheology modifiers.

Systems include: Solution acrylics, polyesters, alkyds and epoxies.

Additions

Add into beginning of grind phase 0.5% to 2.5% based on total inorganic pigment weight. 10% to 20% based on total organic pigment weight.
