ABSTRACT:
This relates to a bonding agent which is used for the production of molded foundry parts and which is composed of two basic components which harden out cold in the mixture of the molded material in the presence of a catalyst under the formation of polyurethane. One basic component is a polyol in the form of a solution of a co-condensate containing an OH group consisting of phenol, aldehyde and an alkyl phenyl siloxane with a contents of at least 3% by weight in free OH groups, if applicable in mixture with a phenol aldehyde condensate containing an OH group, and the second basic component is a polyisocyanate likewise dissolved under normal conditions. Appropriately the solvent has a content in vegetable oils, preferably castor oil.
