UGHIMPROM LLC brings to your attention chemically precipitated chalk produced by precipitation with carbon dioxide, lime milk.

Production Republic of Uzbekistan.

It is used in the production of paint and varnish materials to reduce the cost of raw materials, improve the mechanical properties of paint, increase the shelf life of materials.


 

Main Features:

  • Higher stability, uniform granulometric composition
  • Uniform distribution of particles on the surface, absence of agglomerates
  • Increase in whitening and covering capacity
  • Improvement of the mechanical properties of coatings
  • Use as a rheological additive
