Adding Levasil Colloidal Silica into your silicate paint formulation allows you to improve durability, weather resistance and anti-soiling properties

Potassium silicate in combination with colloidal silica is the main binder in sol silicate paint. With Levasil we offer biocide-free or low biocide solutions. Colloidal silica reduces alkalinity, lowering the pH and solubility of the binder, hence improving the weather resistance of the paint. Furthermore, it helps minimize internal stress, improve film properties and adhesion, otherwise a potential problem in inorganic coatings.

The anti-soiling properties of the sol-silicate paints are a result of colloidal silica making it very hard for dirt to adhere to the painted stone or masonry. All this gives your inorganic coatings qualities that secure longer lasting protection and color.

Bermocell is a high-quality CMC that can be used to create thicker water-based paints with excellent storage stability

Bermocell CMC (sodium carboxymethyl cellulose) is perfect in paints with very high pH such as silicate paints. We are extra proud of our special grade Bermocell 30000 that has a very fast, pH-controlled, dissolution behavior. It has improved rheological properties and at the same time is a stabilizer and water-retaining agent. This grade is easily dispersed in cold water at pH8 or less. After dispersion the pH should be increased to a level of 10 or higher to achieve complete dissolution.

Performance advantages:

Perfect dissolution properties for high pH
Increased water retention
Efficient thickening and good stability

Our Bermocell and Levasil products can be advantageously used together in your silicate paint formulation.

Levasil colloidal silica

Levasil CC151

Levasil CC151 is an alkaline, aqueous dispersion of colloidal silica that is approximately 15% solids by weight. The silica dispersion is sterically stabilized and the amorphous silica particles carry a negative surface charge. The silica particles are discrete, have a smooth, spherical shape, and are present in a narrow particle size distribution. The particles have also been surface modified with an epoxy silane. “Hydroxyl number” for 2-pack systems; 0.45 mole OH/kg product. The physical appearance of the dispersion is a clear liquid, slightly more viscous than water. Levasil CC151 is produced for world-wide distribution.

Levasil CT24 PL

Levasil CT24 PL is an alkaline, aqueous dispersion of colloidal silica that is approximately 30% solids by weight. The silica dispersion is sodium stabilized and the amorphous silica particles carry a negative surface charge. The silica particles are discrete, have a smooth, spherical shape, and are present in a semi-wide particle size distribution. The physical appearance of the dispersion is a clear liquid, slightly more viscous than water.
