| titleOfInvention | Phenolic resin composition for polyurethane cold-box and/or no-bake process and corresponding two-component binder system, use and process |
| abstract | A phenolic resin composition for a polyurethane cold-box and/or no-baking process is disclosed. The phenolic resin composition comprises ortho-condensed phenolic resols having etherified and/or free methylol groups in a total amount of 40 to 60% by weight based on the total mass of the phenolic resin composition; free formaldehyde in an amount of less than 0.1% by weight based on the total weight of the phenolic resin composition; one or more reaction products of formaldehyde with one or more C-H-acidic reactive compounds; other components in a total amount of at least 38% by weight, and the amount of water in the phenolic resin composition in each case does not exceed 1.0% by weight based on the total mass of the phenolic resin composition. In addition, as a formaldehyde scavenger for producing a two-component binder system for a polyurethane cold-box and/or no-baking process, a phenolic resin composition for a polyurethane cold-box and/or no-baking process, C-H-acidic Use of the compound, method for preparing a phenolic resin composition, method for preparing a two-component binder system and method for preparing a feeder, casting mold or casting core from a molding material mixture and finally a corresponding feeder, casting mold and casting core is initiated |
