Paints and Coatings
CR Minerals SafSil® and Navajo Brand pumice grades are widely used in the paint and coatings industry. The low density and unique particle morphology of the vitreous pumice imparts many desirable properties to paint formulations.
SafSil® Products
SafSil® products are high performance functional fillers that contain less than 0.1 % respirable crystalline silica. SafSil® may be used successfully to replace many common fillers such as ground silica, nepheline syenite, calcium carbonate, and talc. “Green” paints may be produced with SafSil® because it is an all-natural material. SafSil® is used in both water and solvent borne systems.

The mild abrasive nature of Navajo Brand pumice makes it an ideal polishing aid to finish acrylic dentures. It is also used in oral hygiene pastes, prophy pastes, and teeth polishing compounds.
