titleOfInvention |
Formaldehyde-reduced phenolic resin binder |
abstract |
The invention relates to formaldehyde-reduced phenol resins of the benzyl ether type, containing at least one formaldehyde scavenger in the form of a beta-dicarbonyl compound and also an alpha-carbonyl-carboxyl compound, especially glyoxylic acid, binders based on these phenolic resins and isocyanate compounds having at least two isocyanate groups for use in phenolic resin-polyurethane cold box processes (PUCB process) and / or phenolic resin polyurethane no-bake processes (PUNB process). Furthermore, the invention relates to molding material mixtures containing the binder and a method for producing cores, molds or feeders. |
