Welcome to Imerys Performance Minerals



  • High brightness
  • Enhanced opacity
  • Reduced TiO2 consumption
  • Improved printability

Alphatex is a high brightness, calcined clay used for coating and filling applications in paper and board where high brightness and opacity are required.

Alphatex is made via a precisely controlled thermal process using a select kaolin feed. The resulting product has a controlled pore structure that maximizes light scattering.

Alphatex provides excellent light scatter and will reduce the need for titanium dioxide (TiO2).

Filling applications

In filling applications, Alphatex improves:

  • Print appearance
  • Strike through
  • Brightness
  • Opacity

Coating pigment
