TALKON A-20

Talc Powder A-20

Impexinvest LLC supplies microtalc for the production of paint materials of the A-20 trademark. This trademark of microtalc can be used as a filler of a wide range of coatings (paints, lacquers, enamels, special corrosion-resistant and heat-resistant coatings, primers, fillers, glues, mastics, sealants, etc.).

Microtalc Talkon A-20 is soft, very white, chemically stable, fine talc powder of exceptional pureness with very low iron content.

The advantages of this trademark of microtalc are the following:

  • High brightness and optimal grain size contribute to the high hide and the opacity of coatings;
  • Plate shape of particles improves the mechanical properties of the film and reduces the permeability of coatings;
  • High chemical resistance and hydrophobicity increase the corrosion-resistant properties;
  • Chemical inertness improves the protective properties and provides excellent interaction with other active ingredients;
  • Lack of amphibole and crystalline silica, low content of heavy metals can create safe and environmentally friendly products;
  • Low abrasiveness reduces the run-out of the equipment;
  • Improves the rheological properties of compositions, prevents the formation of streaks, flake, sedimentation;
  • Allows to adjust the degree and nature of the polishing material, improves the appearance and durability of coatings;
  • Increases resistance to ultraviolet irradiation and degradation caused by high temperatures.
