Over the past several years, there has been a murmur in the coatings industry with regards to the concentration and levels of crystalline silica within various paint formulations, particularly architectural coatings. While there are countless architectural coating formulations, commonly the largest component on a volume basis is calcium carbonate. The combination of the regulatory focus on crystalline silica, in conjunction with the impact calcium carbonate can have on a formulation’s crystalline silica levels, inspired Imerys to both re-evaluate and optimize the processing of calcium carbonate . . .
The combination of the regulatory focus on crystalline silica, in conjunction with the impact calcium carbonate can have on a formulation's crystalline silica levels, inspired Imerys to both re-evaluate and optimize the processing of calcium carbonate to support paint formulators to continue to drive down the crystalline silica levels in their products.
