Abstract

1,184,197. Resin compositions; foundry mixes. ASHLAND OIL & REFINING CO. 1 Aug., 1967 [1 Aug., 1966; 12 July, 1967], No. 35289/67. Headings C3N and C3R. Non-aqueous resin compositions comprise in admixture a resin component, a hardener component, and a curing agent, the hardener being a liquid polyisocyanate containing at least two isocyanate groups, the curing agent being a metal salt which will provide uncomplexed metal ions in the non-aqueous system, and the resin component being an organic solvent solution of a benzylic ether resin which has repeating units of the formula wherein A, B and C are hydrogen, hydrocarbon radicals, oxyhydrocarbon radicals, or halogen, and wherein R<SP>1</SP> is hydrogen or a hydrocarbon radical of 1 to 8 carbon atoms and has been prepared by condensation of a phenol of formula with an aldehyde of the formula R<SP>1</SP>CHO. In a modification the resin component may be a liquid benzylic ether resin of low molecular weight which is not used in organic solvent solution. The compositions are suitably made available as a two-package system comprising the resin component and curing agent in one package and the hardener component in the other package. Exemplified resin components are the condensation products of phenol and paraformaldehyde, the condensation reaction having been carried out in the presence of zinc naphthenate catalyst, which catalyst is retained in the resin and acts as the curing agent in the compositions. Additional catalysts may, however, be added to the resin component. Such catalysts are, for example, lead neodecanoate, zinc neodecanoate, lead naphthenate, manganese naphthenate, zinc naphthenate, calcium naphthenate, stannous octoate, zinc lactate and dibutyl tin dilaurate. The preferred polyisocyanates are aromatic polyisocyanates and particularly 4,4<SP>1</SP>-diphenylmethane diisocyanate, 4,4<SP>1</SP>,4<SP>11</SP> - triphenylmethane triisocyanate and mixtures thereof. It is preferred to employ mixtures of aromatic and polar solvents. The compositions are suitable as binders admixed with sand to form a foundry mix. Apart from sand such mixtures may contain iron oxide, ground flax fibres, wood cereals, pitch, refractory flours and particularly a silane of the formula wherein R<SP>1</SP> is a hydrocarbon radical and preferably an alkyl radical of 1 to 6 carbon atoms and R is an alkyl radical, alkoxy-substituted alkyl radical or alkylamino-substituted alkyl radical in which the alkyl groups have 1 to 6 carbon atoms, to improve the adhesion of the binder to the sand.
