DORKAFILL® H – the multi-talented filler

DORKAFILL® H is a calcined kaolin which is in a class of its own. We extract the multi-functional filler from our own deposits and put it through a sophisticated refining process. It is often used by leading manufacturers in their dispersion paint formulations, and for good reason. DORKAFILL® H gives dispersion paint a performance boost which can be exploited in different ways:

  • To reduce system costs, without making compromises in the performance of dispersion paint
  • To upgrade existing formulations to make higher-grade paint with better performance and higher margins without adding cost to the formulation.

Two ways to increase your earnings

Multi-functional DORKAFILL® class fillers give dispersion paint a performance boost which you can use to upgrade and/or reduce the system costs of your formulations.

Use of mono-functional fillers

On many optimization projects where Dorfner Paint applications engineering was involved, multi-functional DORKAFILL® class fillers simplified the formulations and reduced the number of different raw materials. DORKAFILL® H on its own or together with DORKAFILL® PRO_VOID used in existing filler packages can completely replace all of the conventional mono-functional fillers or combinations of those fillers, e.g. talcum, diatomite, mica, aluminum silicate or precipitated calcium carbonate (PCC).
