Gloxil bright

The product is a calcined kaolin. This treatment enhances the chemical purity as well as the thermal stability of the material, providing it with excellent optical and functional properties such as brightness, opacity, and light scattering.

Fields of application

Elastomers

  • for any rubber products
  • suitable vor very bright or white compounds

 

Adhesives and sealants

Paints & varnishes

  • road marking paints
  • coil coatings
  • powder coatings
  • emulsion and silicate paints
  • industrial paints
  • wood and foil coatings
  • primers and surfacers
  • electrophoretic paints


Benefits

Elastomers

  • low sieve residues
  • good and rapid incorporation
  • very good dispersion
  • good flow properties
  • less moisture absorption
  • very high brightness, color-neutrality
  • excellent surfaces
  • excellent extrusion properties
  • no negative influence on curing rate
  • low tensile and compression set
  • high electrical resistance
  • good aging properties
  • high chemical resistance
  • matting effect
