Steamat

Steamat® A cost-effective matting agent for decorative paints

  • A regular and deep matting effect
  • Easy application
  • Improved scrub and weathering resistance

Steamat® is an innovative, engineered talc-chlorite, specifically designed to give a rich, deep matt finish in a cost-effective formulation.

Steamat® has: 

  • A specially defined particle size distribution which diffuses light with high efficiency from the paint film, giving a deep matting effect
  • A lamellar morphology, which gives the paint film good mud-cracking resistance while maintaining opacity and porosity
  • A specific mineralogy that allows easy incorporation in both solvent- and water-borne systems
  • A high apparent density which allows easy dispersion into the paint during manufacture

It provides excellent scrub and weathering resistance to interior and exterior paints.
