Ceridust 5551 is recommended for solvent and water based coatings. In powder coatings it acts as wetting and dispersing aid. 

In solvent and water based coatings the micronized wax additive creates an excellent scratch resistance. The strong matting effect makes the Ceridust 5551 to a very effective matting agent. Also the slip performance can be influenced by the Ceridust 5551. In addition the surface modification of wood coatings creates an outstanding soft feel touch. The chemical composition of the micronized powder makes it also very stable in water based coatings. There is no flooding or settling of the wax. 

Ceridust 5551 is a fine particle dispersing agent and is recommended for engineering polymers like PA, PC, PET, PBT, TPU, etc. The micronized dispersing agent particles are close to the pigment particles and being almost statistically ideally distributed, show a high likeliness to find a place between pigment particles, thus separating them from each other. Consequently those pigment particles will not form agglomerates. The early melting behavior of micronized particles leads to a coating effect of the pigment particles and neutralizes the binding forces of pigment particles, prevents them from re-agglomeration, eases pigment dispersion and stabilizes the dispersion. A mixture of standard powder and Ceridust already improves the color strength as well as the filter pressure value.
