Compositions containing unsaturated fatty esters may be stabilized against atmospheric oxidation by the addition of an antioxidant package containing a phenolic oxidant and a nonphenolic oxygen scavenger, which may be a hydroxylamine, an amine N-oxide, an oxime, or a nitrone. If an amine N-oxide is used, it may be used with or without a phenolic antioxidant. Compositions treated in this manner show good resistance to atmospheric oxidation and resultant viscosity increase.

Fatty ester compositions with improved oxidative stability

The invention relates to anti-skinning agents containing mixtures of organic compounds (combinations of additives), whereby the organic compounds are selected from the groups of (a) organic hydroxylamines and (b) alkylamines and/or alkyl alkanolamines and also relates to compositions containing the combination, especially oxidatively drying paints or coating compositions and article coated with such oxidatively drying paints or coating compositions.

Antiskinning compound and compositions containing them

The invention relates to a coating material, paint or finish which contains as anti-skinning agents a combination of at least two organic and/or inorganic oxygen scavengers and also relates to compositions containing the combination, especially oxidatively drying paints or coating compositions and articles coated with such oxidatively drying paints or coating compositions.
