PRODUCT TYPES

Coated or uncoated?

Two surface treatments, one limestone. Pick the family first, then the grade.

Coated powder

Treated with stearic acid for dispersion in polymer systems and higher moisture resistance
  • Improved dispersion in polymer systems
  • Higher moisture resistance
  • Films, sheets, rubber, adhesives and sealants

Unoated powder

Natural, untreated powder that improves stiffness, whiteness and opacity.
  • Higher mechanical strength and stiffness
  • Better whiteness and opacity
  • Paper, paints, rigid PVC pipes and construction
