Application Information

Coatings and Printing Inks
Special Features and Benefits

The additive has a matting effect and simultaneously improves scratch resistance, metal marking resistance and sandability. It is recommended for solvent-borne and aqueous systems.

Recommended Levels
0.5-10% additive (as supplied) based on the total formulation, depending on the desired degree of gloss.
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 is preferably incorporated into the coating at the end of the production process at a moderate shear rate.

 

Powder Coatings
Special Features and Benefits

The additive is recommended for matting UV powder coatings and it also improves surface hardness and therefore surface protection.
Recommended Use
Ceraflour® 920 is recommended for all UV-curable powder coatings. The matting effect can be reinforced in combination with Ceraflour® 950.
Recommended Levels
2-8% additive (as supplied) based on the total formulation, depending on the desired degree of gloss.
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 be mixed with resin, hardener, pigments and other additives using a high-speed mixer and extruded along with all the components.
