BUSPERSE 275E

BUSPERSE 275E is an anionic dispersing agent composed of water-soluble polyelectrolytes. It is used as a pigment dispersant in various formulations to provide long-term viscosity stability and to avoid crystal formation and agglomeration of pigment. BUSPERSE 275E is highly effective as a pigment dispersant to provide improved gloss, hiding power and reduction of ridges and valleys from brush marks in the dried film. It can be employed in formulations containing reactive pigments or pigments with some water solubility. BUSPERSE 275E in combination with other additives results in a more stable suspension of solids and better handling characteristics enabling longer storage periods without significant settling of solids or loss of fluidity.
