Colloidal Silica for Architectural Coatings

Architectural paints, including interior and exterior primers, sealers, varnishes, and stains, bring aesthetics and functional enhancements to building and construction applications. Over time, the cleanliness of the coating is impacted by dirt, debris, and general wear and tear. Coating degradation from cleaning becomes a challenge, often resulting in the need to redo the coating.

Stronger Coating, Easier Cleaning

LUDOX^® colloidal silica greatly reduces dirt pick-up, enhances wet scrub resistance, and increases water vapor permeability without impacting waterproofing properties in architectural coatings.

These discrete, spherical, amorphous particles bring diverse benefits to architectural coatings, including:

• Reduced dirt pick-up – enables formulators to reach the best dirt pick-up resistance (DPUR) classification according to UNI 10792
• Wet scrub resistance – strengthens the coating and enhances wet scrub resistance, particularly in high PVC systems
• Water vapor permeability – increases water vapor permeability without impacting water permeability

Weathering Resistance and Storage Stability

LUDOX^® colloidal silica does not adversely affect other coating properties like weathering resistance and storage stability. Compatible with a wide range of polymeric-type binder systems, Grace’s global technical services team can advise the right grade based on pH and commercial application.
