Troy Corporation offers Troysperse 90W, a high performance universal pigment dispersant for both aqueous and solvent systems. Troysperse 90W, which acts as a dispersant and wetting agent, can enhance the properties of many products and applications including inks, architectural and industrial coatings and color dispersions. It is effective with both organic and inorganic pigments, and promotes excellent dispersion of difficult-to-disperse organic and carbon black pigments
The product is a water-soluble polymer that forms a powerful bond with the surface of the pigment and stabilizes the dispersion through electrostatic forces. Troysperse 90W reduces milling time, increases pigment loading and enhances flocculation stability, resulting in faster dispersion time and improved hiding and rheology, according to the company.
