Specialty Dispersants

Lubrizol's hyperdispersant technology allows the production of highly loaded, highly stable and broadly compatible dispersions in almost any combination of solid particles and continuous phases (liquid or solid). This dispersant technology combines polymeric stabilizing chains selected for solubility in a given solvent and/or resin combination, with anchor groups optimized for strong adsorption to the particle surface, where the dosage is determined by the particle's surface area. This technology allows the production of sterically stabilized dispersions with higher solids content, lower viscosity, and improved viscosity and particle size stability compared to dispersions made using resins or lower molecular weight dispersants.

Solplus™ hyperdispersants and coupling agents as well as Lubrizol® polymeric dispersants provide high pigment/filler loading and increased color strength in thermoset and thermoplastic applications, such as unsaturated polyester- or polyol-based color concentrates and liquid or solid color masterbatch. Solplus hyperdispersants are also suitable for a wide variety of pigment and particle treatment applications.
