Abstract (en)
[origin: WO2019121637A1] A description is given of a method (i) for producing a metal casting or (ii) for producing a cured moulding for use when casting metal castings. Also described is the use of an aliphatic polymer crosslinked by etherification and comprising structural units containing hydroxy groups as a binder of a moulding for use when casting metal castings. Likewise described is a moulding for use when casting metal castings, comprising at least one basic moulding material and a cured binder comprising or consisting of an aliphatic polymer crosslinked by etherification and comprising structural units containing hydroxyl groups. Also described is a cured moulding that can be produced by a method according to the invention, and also a moulding material mixture for use in the method according to the invention.
