Provides high efficiency to disperse inorganic pigment, especially titanium dioxide.

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.

About 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.

Targeted Applications and Markets

• Wood coatings 
• Protective coatings 
• Industrial coatings
• Automotive OEM and refinish paints 
• Printing inks 
• Pigment pastes

Advantages of DOWSIL 700P Additive

• Highly efficient dispersant for titanium dioxide pigments in a broad range of solventborne paints and inks 
• Improves pigment utilization and reduces millbase viscosity 
• Provides high gloss and low haze Low yellowing under high-temperature conditions 
• Reduces pigment flooding and floating for improved color consistency and color matching
• Low-VOC and low-odor

Highly Efficient

Effective at a much lower dosage than competitive dispersants, DOWSIL 700P Additive also delivers higher gloss and lower haze.

Good Storage Stability

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.

Resistance to Yellowing at High Temperatures

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

Effective Prevention of Pigment Flooding and Floating

DOWSIL 700P Additive effectively prevents pigment flooding without increasing paint viscosity or reducing gloss.
