The invention relates to a method for the layer-wise building of bodies comprising a refractory mold base material and resoles, to three-dimensional bodies manufactured according to said method, and to the use thereof in metal casting. According to the method, the refractory mold base material is contacted with at least one ester to obtain an ester-impregnated mold material mixture.

Method for the layer-wise building of bodies comprising refractory mold base material and resoles, and molds or cores manufactured according to said method

The invention relates to mold material mixtures on the basis of inorganic binders, for producing molds and cores for metal casting. Said mixtures consist of at least one refractory mold base material, an inorganic binder and amorphous silicon dioxide as an additive. The invention also relates to a method for producing molds and cores using said mold material mixtures.

Mold material mixtures on the basis of inorganic binders, and method for producing molds and cores for metal casting

A method for producing cores and molds for the foundry industry utilizing a flowable fire-resistant primary molding material. The method includes an acid applied to the flowable fire resistant primary molding material to obtain an acid-coated fire-resistant primary molding material. A binder that can be cured by acid is applied to the acid-coated fire resistant primary molding material to obtain a fire-resistant primary molding material coated with a binder. The fire-resistant primary molding material coated with a binder is then molded into a molded body, and-the molded body is cured. The acid used is a mixture of methane sulfonic acid and at least one sulfur-free acid. The casting molds can be produced having reduced emission of harmful compounds during casting.

Catalysts comprising methane sulfonic acid for the acid hardening method

The invention relates to a casting mould for the casting of metals, wherein a layer consisting of a material which absorbs harmful substances on at least sections of gas outlet surfaces of the casting mold, in particular the top side thereof. The invention also relates to a coating composition, to a process for producing the casting mold and to the use thereof for casting of metals.

Coating composition which adsorbs adourous and harmful substances and is intended for the box casting of metals
