Busperse® 39 

Busperse® 39 is a high solids, anionic dispersant used in water-based paints and pigment slurries. It is effective at very low concentrations and does not require the use of additional dispersants or wetting agents during the pigment-grinding stage. Busperse® 39 also provides excellent viscosity stability when using reactive pigments. It exhibits good color acceptance, is low foaming, and is not corrosive. Busperse® 39 has good compatibility with glycols and is therefore well-suited for use in gloss latex paint formulations. This product is a translucent, pale yellow liquid.
