Foundry coatings are used widely in the foundry industry to improve the surface quality of the metal parts, especially when complex geometries are casted. To achieve an optimal performance a number of additives are used (e.g. rheology additives, wetting and dispersing additives) to taylor the properties of the foundry coating.
BYK phyllosilikates/ organoclays can be used to modifiy the rheology of the coating and influence the flow behaviour. BYK wetting and dispersing additives improve the dispersion of the solid particles.
