Dow Corning 700P additive improves pigment dispersion

Dow Corning 700P Additive. This low-VOC, low-odour siloxane-based additive is an efficient pFormulators of white, pastel and grey solventborne paints and coatings now have a new cost- and performance-enhancing ally, igment dispersant that enables formulators to achieve stable titanium dioxide (TiO2) pigment dispersions with a reduced tendency toward flooding and floating, and improving colour consistency.

When used at 10-15% of the dosage required for ordinary organic dispersants, the additive provides equal or better performance. It has been shown to be effective with higher and lower grades of TiO2.

It has a higher heat resistance than organic dispersants. Consequently, formulations containing this dispersant show significantly reduced yellowing during heat-curing and when overbaked.

"Highly effective at low use levels, Dow Corning 700P Additive offers coating formulators an efficient and cost-effective solution for improving pigment utilisation,” said Dow Corning Coatings Global Segment Leader Chris Wall.

"It can reduce the millbase viscosity and improve the gloss and haze of solventborne paints and coatings based on TiO2 pigments, even after storage. And it makes it easier to achieve an exact colour match when tinting these paints and coatings.”
