Abstract
The invention concerns a binder system which encompasses a phenolic resin component and a polyisocyanate component, characterized by the phenolic resin component having an alkoxy-modified phenolic resin, where less than 25 mole-%
of the phenolic hydroxy groups are etherified by a primary or secondary aliphatic alcohol with 1 to 10 carbon atoms.
of the phenolic hydroxy groups are etherified by a primary or secondary aliphatic alcohol with 1 to 10 carbon atoms.
