DOW CORNING: Pigment Dispersant
Dow Corning® 700P additive is a new low-VOC, low-odor siloxane-based additive. This highly efficient pigment dispersant reportedly enables formulators to achieve stable titanium dioxide (TiO2) pigment dispersions with a reduced tendency toward flooding and floating, improving color consistency.
When used at 10-15% of the dosage required for ordinary organic dispersants, the new additive can provide equal or better performance. It also has been shown to be effective with both higher and lower grades of TiO2. The additive also reportedly has a higher heat resistance than organic dispersants; consequently, formulations containing this dispersant show significantly reduced yellowing during heat-curing and when overbaked.
Targeted markets and applications for the additive include solvent-based wood coatings, protective coatings, industrial coatings, automotive OEM and refinish paints, printing inks, and pigment pastes.
