Wollastocoat

Our versatile, color-functional carbon black filler

Our Wollastocoat wollastonite is a fine-particle-size, low-aspect-ratio calcium silicate that has been chemically modified to give it ideal properties as a carbon black replacement filler.

The Wollastocoat range is particularly recommended for replacing carbon black in color-sensitive fluoroelastomer O-ring and gasket applications.

Replacing carbon black N990 with Wollastocoat® 1250 or Wollastocoat® M1250 coated wollastonite (at the same phr) in a fluoroelastomer (FKM) with a bisphenol cure system will give you the following benefits:

  • Improves compression set
  • Shortens curing times
  • Maintains torque
