Hubercarb® calcium carbonate is an economical material for powder coatings.  It is non-toxic, has a neutral color tint and low abrasiveness.  Fineness and particle size distribution determine the opacity.  Huber's high performing line-up of Hubercarb calcium carbonate products can improve the physical and rheological properties of powder coatings.
