| titleOfInvention | Polyurethane-based binder system for the manufacture of foundry cores and molds using cyclic forms, mixing of material to be molded and process |
| abstract | Binder for mixtures of material to be molded containing (A) at least one phenolic resin component as a polyol component having a phenolic resin, wherein the phenolic resin can be obtained from the reaction of a phenol compound and a compound of aldehyde, (B) at least one isocyanate component having at least one polyisocyanate with at least two NCO groups per molecule and (C) at least one solvent component presenting a cyclic formal, possibly also as part of the components (A ) and / or (B), in addition to the case, another solvent, the cyclic formal having the following formula: ** Formula ** in which X is -C (R5) (R6) - or -R7-O-R8 - n represents from 0 to 4 and R1 to R6 independently of each other represent H or a hydrocarbon group, in particular alkyl group, with 1 to 6 C atoms, the hydrocarbon group may contain one or more ether groups and / or one or more ester groups and / or may be substituted with carb group (s) onyl and / or OH groups, and R7 and R8 independently of each other represent a methylene, ethylene or propylene group, or is selected from 1,4-butanediolformal, glycerolformal, ethylene glycolformal, propylene glycolformal or 1,2-butanediolformal. |
