Additives for Foundry and Refractory

Bentonite based clays play an important role in many formulations for the foundry and refractory industry. As binders in mortars or ramming mixtures, the BENTOLITE grades stand out for their very low ferrous/iron content. Foundry coatings require a unique set of properties where BYK additives can help to balance substrate wetting, defoaming and rheology behavior of the foundry coatings.
