Abstract
The invention provides anti-skinning compositions for use in manufacturing oil-based coating materials. The novel anti-skinning compositions are clear, homogeneous solutions of cyclohexanone oxime that can be prepared by dissolving cyclohexanone oxime in a suitable carboxylic acid or mixture of carboxylic acids. Suitable carboxylic acids include fatty acids, such as fatty acids of tall oil distillate. Surprisingly, the fatty acids are useful as delivery solvents over a useful range of temperatures and have desirable flash points. They are compatible with many oil-based coating materials. The anti-skinning compositions and manufacturing methods of the present invention are especially useful in the manufacture of oil-based paints containing metal carboxylate driers.
