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.

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.

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.

  • DOWSIL™ 983 Structural Glazing Sealant Base and Curing Agent

    Designed for specialized use where dual structural and weatherseal applications are desired for factory glazing and curtainwall production. Once cured, this structural sealant forms a durable, flexible, watertight bond that can be warranted for 20 years and used in ±25% movement weatherseal applications. It has excellent unprimed adhesion to glass, alodine, and anodized aluminum1, although DOWSIL™ Primer-C OS is recommended for fast and consistent adhesion, especially to high-performance substrates approved for architectural structural glazing applications.
