Refining - the secret to success

Kaolin is the raw material which we base our multifunctional filler materials on. We extract exceptionally high quality kaolin from our own natural mineral deposits which are extensive enough to ensure security of supply for many generations to come. We have the expertise needed to convert raw kaolins into multifunctional fillers. This know-how is our most prized asset, and we use it to create genuine value-add for the customer. However, before this unique material can be used in paint and coatings, it first passes through a complex series of processing and refining steps at Dorfner. The result is top-grade calcined kaolins marketed under the DORKAFILL^® H, DORKAFILL^® Pro_Void, DORKAFILL^® X_Pand and DORVALIT^® SHO brands which have an excellent reputation in the paint and coatings market. Their versatility and advantages have been demonstrated in many effective formulations.
