Abstract: Air-drying alkyd resins which are in the form of neutralized semi-esters of hexahydrophthalic acid anhydride constitute an excellent basis for coatings which undergo virtually no yellowing and which, even when aged by heat, show a high constancy of color.
Abstract: Binder Compositions comprising a solution of furan foundry binders in an alkylated aromatic hydrocarbon solvent result in a more cost efficient binder. The cost efficiency is achieved without significant loss of physical properties of the foundry cores and molds which are formed using the binder. In instances the binder compositions of this invention exhibit improved physical properties.
