A coating composition is described, for use in the foundry, in particular comprising particulate, amorphous silicon dioxide (SiO) and an aqueous phase having a pH of at most 5, and also coated, waterglass-bound foundry molding elements, especially coated, waterglass-bound foundry molds and foundry cores, which each comprise a coating composition of the invention. Further described is the use of a coating composition of the invention for producing a coating on a waterglass-bound foundry molding element and a method for producing a waterglass-bound foundry molding element (mold or core) coated with a water-containing refractory coating. Likewise specified is a kit whose contents include a coating composition of the invention.

Coating composition for the foundry industry, containing particulate, amorphous silicon dioxide and acid

A refractory coating for producing mold coatings by application to inorganically or organically-bound molding materials in lost molds or to cores for iron and steel casting is disclosed. The refractory coating can have a proportion by weight of 0.001% or more and less than 1% of inorganic hollow bodies, which partially or fully consist of crystalline material and have a softening point of 1000&#xb0; C. or higher.

Refractory coating for producing mold coatings

The present invention relates to a refractory coating for producing mold coatings by application to inorganically or organically-bound molding materials in lost molds or to cores for iron and steel casting, wherein the ready-to-use refractory coating has proportion by weight of 0.001% or more and less than 1% of inorganic hollow bodies, which partially or fully consist of crystalline material and have a softening point of 1000&#xb0; C. or higher.
