Foundry molding compositions |
| abstract |
These compositions comprise sand, a novolac binder resin and a hot distortion additive comprising a modified novolac resin which is prepared by co-reacting an alkylphenol with phenol and formaldehyde or by post-alkylating the novolac resin by means of alkylating compounds selected from alkenes, vinyl benzenes and unsaturated alicyclic compounds. |
