Lithomer R


Nomenclature and chemical formula

Mixture of titanium dioxide and barium sulphate - TiO2 + BaSO4

Characteristics

Lithomer R is a fine white powder, stable on air, without odor, non-flamable, non-explosive, non-poisonous.

Applications

  • For solvent and powder coating industries

LITHOMER R

  • An inspiriting innovation of white pigment opacifier attained by means of Co-precipitation, under special controlled post production treatment which obtains ultrafine particle size distribution is typical of this product and is optimally adjusted for optical rheological properties.
  • White pigment´s relative scattering, high lightness, neutral white colour and it´s diffuse reflectance enable paint and coating producers to save costs via partial replacement of TiO2 with highgloss
