Reduces Pigment Flooding and Floating
Low Yellowing Under High-Temperature Conditions
Low-VOC and Low-Odor
Improve dispersion of TiO2 pigments in solvent-based paints, reduce the risk of flooding and floating, and reduce yellowing at high temperatures with an innovative silicone additive from Dow Consumer Solutions.
If improving the dispersion of titanium dioxide pigments, improving gloss and reducing haze, and improving resistance to yellowing during high-bake or over-bake conditions are important to you, consider DOWSIL™ 700P Additive.
At very low concentrations, this siloxane-based dispersant effectively disperses inorganic pigments, preventing pigment flooding and floating in solvent-based formulations – particularly TiO2-based whites, grays and pastel shades. It offers good cost-in-use compared to competitive products, and compared to organic dispersants, it is remarkably resistant to yellowing at high temperatures. Plus, it can be added in pigment grind or during let-down for formulating flexibility.
Effective at a much lower dosage than competitive dispersants, DOWSIL 700P Additive also delivers higher gloss and lower haze.

DOWSIL 700P Additive creates stable, non-flocculated TiO2 dispersions, outperforming competitive solutions at a significantly lower dosage. Formulations treated with DOWSIL 700P Additive display good gloss and low haze over time; while formulations treated with competitive dispersants lose gloss, and their haze increases.

When subjected to high temperatures DOWSIL 700P Additive resists yellowing, while organic dispersants darken significantly.
