Additives for paints

In addition to powder coating and additive manufacturing, Rilsan® PA11 powders can be used as additives in industrial coatings to improve properties and impart texture.

For more textured finishes and better cleanability, Orgasol® ultrafine powders with a spheroidal shape and smaller particle size are also available. Visit Orgasol® powders website.

Rilsan® D Range

Compatible with a wide range of paints, Rilsan® D is well known by paint manufacturers for its combination of properties including:


  • High degree of scratch and abrasion resistance
  • Matting effect
  • Feeling/touch: the wide granulometry range and angular shape particles lead to a specific coating texture from finely granulated to sharply structured
  • Covering properties with mass pigmented products
  • Special multicolour effects with mass colored grades
  • Good chemical resistance
  • Low density

3 main additive markets

  • Coil coating
  • Flooring: PVC, concrete, sport flooring
  • Plastic Coating: PVC profiles, automotive parts, video/Hi-Fi equipment

Rilsan® Fine Powders exhibit a full dispersibility in liquid media (polyurethane, epoxy formulations, etc.), and a regular size distribution which provides a regular structured coating aspect.
