Paints and Coatings

PQ Corporation manufactures many silicate and silica gel products for use in paints and coatings.

PQ's GASIL® Silica Gel products are specifically designed as an effective matting agent for Coil, Wood, General Industrial, and other Surface Coatings Applications. This product technology provides excellent matting efficiency combined with minimal effect on clarity and mechanical film properties. For more detailed information we refer to the Surface Coatings section.

PQ's KASIL® Potassium Silicate is used as a binder in zinc-rich paint formulations for corrosion protection. In decorative coatings KASIL potassium silicate does not form white carbonate films and they do not hide pigments. As a result, KASIL potassium silicates yield clear, rich colors with a soft quality – perfect for decorative pigments that are applied to stone, concrete, stucco, brick, and metal surfaces.

How It Works
PQ GASIL® silica gels introduce surface roughness to films and coatings to modulate surface sheen and gloss.  The product technology provides excellent matting efficiency combined with minimal effect on clarity and mechanical film properties. Other product performance benefits are in product consistency, ease of dispersion, and in providing raw material cost savings.

PQ liquid potassium silicates are water-based solutions of silica.  All liquid silicates dry (dehydrate) to form films or coatings on surfaces. These films dry to a rigid, glass-like state and depending on ratio have different drying rates and final moisture contents. (Higher ratio products have faster rates and dry harder.) Silicates can be used as a vehicle to bind pigments and other powdered materials to surfaces, especially masonry. They can also be used as a corrosion inhibitor on metal surfaces in coating formulations, for example zinc-rich paints. Other coating applications would include surface strengthening, surface texture, and development of heat-resistant and intumescent films.
