Ceraflour® 1051

Coatings Industry
Special Features and Benefits
The mechanical properties of Ceraflour® 1051 are comparable to those of a typical PE/PTFE wax. The additive improves the scratch and abrasion resistance of aqueous, solvent-borne, solvent-free, and UV coating systems. The surface slip is slightly increased. As a result of the extra-fine particle size distribution, the additive can also be used in clearcoats and in coating systems with low film thickness. It has only a very minor effect on gloss and haze. In aqueous systems, Ceraflour® 1051 has matting properties due to the particularly good orientation toward the surface. In such systems, the organic cosolvent content should be at least 5-10 % in order to avoid creaming of the wax additive. Ceraflour® 1051 has
outstanding abrasion resistance in a broad spectrum of application areas compared to a PE/PTFE wax.

Recommended Levels
0.2-5% additive (as supplied) based on the total formulation.
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 a medium shear rate at the end of the production process. The temperature should remain below 40 °C to prevent swelling of the wax particles. Alternatively, Ceraflour® 1051 can be pre-dispersed in these organic solvents or in a mixture of these solvents and binders that are components of the respective coating formulation. This facilitates the incorporation. A typical dosage for pre-dispersion is between 15% and 25% Ceraflour® 1051. Pre-dispersion in water is not possible.
