Patent number: 5027890Abstract: The invention relates to foundary moulding compositions useful for producing moulds for the manufacture of metal castings wherein the moulds are capable of giving castings with good surface finish without the need for conventional separate blacking applications. A foundary moulding composition of the invention comprises refractory material such as sand, alkali phenol-formaldehyde resole resin solution, carbonifiable material such as styrenated phenol, and an effective amount of an organic ester for hardening the composition. In another embodiment, the invention is a binder composition comprising alkali phenol-formaldehyde resole resin solution and carbonifiable material capable of being hardened by reaction with organic ester. In another embodiment, the invention is a curing additive for a foundry binder comprising carbonifiable material and liquid ester such as gamma-butyrolactone, and the like.Type: GrantFiled: October 5, 1990Date of Patent: July 2, 1991Assignee: Borden (UK) LimitedInventors: Peter H. R. B. Lemon, Jeffrey D. Railton, Derek W. Baker, John Ireland
