Special Features and Benefits

The additive has a matting effect and simultaneously improves scratch resistance, metal marking resistance, and sandability. It can be used in most coating systems.

Recommended Use

  • Architectural coatings
  • Protective coatings
  • Industrial coatings


Recommended Levels
0.5-10% additive (as supplied) based on the total formulation, depending on the desired gloss level. The above recommended levels can be used for orientation. Optimal levels are determined through a series of laboratory tests.
Incorporation and Processing Instructions

The additive should preferably be incorporated into the coating at a medium shear rate at the end of the production process.

Special Note

Ceraflour® 921 contains 15 weight percent water. However, the water is chemically bound and cannot be released into the coating formulation. The additive therefore has a solids content of 100% and contains no volatile components. For this reason, Ceraflour® 921 is also very stable in solvent-borne systems and in solvent- free UV systems. The water content increases the polarity of the additive, however, and thereby enables easier incorporation into aqueous systems. Ceraflour® 921 may react with some binders, e.g. moisture-curing polyurethanes.
