TEGO Dispers 670 is a high molecular weight wetting and dispersing additive for pigments and fillers. The product is a thermally stable polymeric dispersant built from modified polyester chains that dramatically lower the interfacial tension between pigment particles and the surrounding resin matrix. Its amphiphilic architecture, containing both hydrophilic and hydrophobic segments, enables stable dispersions even at very high pigment loadings, preventing agglomeration, sedimentation, and flocculation. Excellent color strength and gloss are achieved through uniform particle distribution, which reduces light scattering and maximizes optical density of the coating. Newtonian rheology provides predictable flow behavior during application, allowing formulators to control viscosity without the need for additional thickeners. Concentration 40% in MPA/DBE (1:1) gives formulation flexibility: MPA (methyl‑pentanol) and DBE (dibutyl ether) are compatible with a wide range of resin systems, from acrylics and polyurethanes to epoxy and polyester binders. Shelf life 48 months. Dosage 1–5% on pigment makes the additive economical and easy to integrate into production lines. Used in industrial coatings, automotive paints, pigment pastes, and all types of pigments, including organic, inorganic, metallic and pearlescent grades. In automotive lacquer systems TEGO Dispers 670 is often paired with corrosion‑inhibiting additives and plasticizers, improving metal adhesion and UV resistance. In industrial coating formulations it works well with epoxy and polyester resins, accelerating cure and enhancing chemical resistance. For high‑impact protective coatings, formulators typically target the upper end of the dosage range to ensure maximum pigment stabilization. When preparing pigment pastes, the recommended practice is to pre‑disperse TEGO Dispers 670 in the chosen solvent, then introduce the pigment gradually under high shear mixing to achieve a homogeneous, bubble‑free dispersion.
