Pigment pastes are used to colour all kinds of products like coatings, paints, inks, plastics and composites. Due to increasingly strict VOC regulations, producers are forced to decrease the use of solvents in their products, which leads to more water based and high solid products. By decreasing the solvent or increasing the pigment loading, pigment pastes will have less flow. Flow is a crucial characteristic for any pigment paste, therefore other solutions are needed to meet new regulatory requirements.
We have developed a wide range of dispersants, defoamers and levelling agents to ensure continuity of meeting these demands. These additives are aimed at enhancing colour characteristics and providing stability to the pastes. Simultaneously pigment loading can be increased and viscosity can be reduced providing higher solids and decreased VOC.
Due to the variety of applications, several dispersants are recommended. Products are summarized according the application (water, solvent-based and solvent-free) and pigments. This allows for a more accurate choice of dispersants. Besides the general recommendations below, we offer specific recommendations upon request.
