Matting Imerys Minerals Make Cost-Effective Matting Agents

Matting Agents and its effect on the color and rheology of matted coatings not only decreases the gloss of surfaces, but also affects their color and rheological properties. For manufacturers of paint, the difficulties often lie in meeting stricter environmental standards and adapting to new application and print technologies. 

Imerys offers a wide solution of natural minerals for matting paints. Imerys minerals are cost-effective alternatives to silicas and waxes often used in matt paints. Imerys Minerals with a specific particle size distribution, diffuse light from the paint film, providing a smooth and deep matting effect. Imerys offers our formulator options to achieve significant matting without losing opacity in both water and solvent-borne, high and low PVC systems. 

Imerys minerals with a specific particle size distribution diffuse light from the paint film, providing a smooth and deep matting effect. They are ideal for use in both water- and solvent-borne high and low PVC paint lines.

Recommended grades

  • OpTiMat® matting agent products provide maximum matting efficacy and allow formulators to formulate the dead flat paint line at a very lower loading. OpTiMat’s lameller morphology also reinforces the film and helps in reducing mud cracking issues in high PVC paint lines and improve burnish and touch up performance. 
  • Celite flux-calcined diatomaceous earth products have very high whiteness and lower “b” value and provide high matting efficacy waterborne architectural paint lines. The irregular shape morphology exhibits excellent burnish and touch performance in mid to high PVC paint lines. 
  • DiaFil grades are the natural diatomaceous earth silica based product designed to provide maximum matting efficacy with excellent film properties, burnish and touch up performance. DiaFil grades contain crystalline silica less than 0.2%
