摘要： The present invention relates to a binder system that comprises a phenolic-resin component and a polyisocyanate component. This system is characterised in that the phenolic-resin component includes an alkoxy-modified phenolic resin, wherein less than 25 mole % of the phenolic hydroxy groups are etherified with a primary or secondary aliphatic alcohol comprising between 1 and 10 carbon atoms.

摘要： The invention relates to a phenolic resin and a binding agent containing said resin, which is particularly suitable for producing casting moulds and cores. The phenolic resin is obtained by condensing phenols and aldehydes. A mixture of substances can also be used as an additional starting material. Said mixture appears as a residue during production of bisphenol, i.e. as bisphenol A tar.
