Abstract
Disclosed is an improved autoxidizable coating and/or impregnating composition containing (1) a reactive non-volatile diluent monomer system of a mixture of dicyclopentenyloxyalkyl esters of polymerizable ethylenically unsaturated carboxylic acids and methacryloxyalkyl esters of drying or semi-drying oil fatty acids (2) a film-forming component which contains autoxidizable functionality, (3) a polyvalent metal containing salt or complex that catalyzes the autoxidative curing of (1) and (2), and, optionally, (4) a volatile oxime stabilizer.
Claims20
A coating and/or impregnating composition, adapted to be cured in the presence of oxygen, comprising:
- (1) from about 5% to about 75% by weight, based on the total of components (1) and (2), of a reactive, non-volatile, diluent monomer system comprising
- (a) from about 1% to about 99% by weight of monomer system of at least one member selected from the group consisting of dicyclopentenyloxyalkyl esters of a polymerizable ethylenically unsaturated monocarboxylic acid or dicarboxylic acid, and
- (b) from about 1% to about 99% by weight of monomer system of at least one member selected from the group consisting of methacryloxyalkyl esters and acryloxyalkyl esters of drying oil, or semi-drying oil, fatty acids;
- (2) from about 95% to about 25% by weight, based on the total of components (1) and (2), of a film-forming component selected from the group consisting of
- (a) drying oils,
- (b) film-foring alkyd resins having autoxidative functionality and oil-free polyesters having maleate or fumarate functionality,
- (c) film-forming vinyl addition polymers having ethylenic unsaturation having autoxidizable characteristics selected from those vinyl addition polymers having pendant allylic functionality and those vinyl addition polymers having pendant drying oil functionality,
- (d) film-forming polymeric binders lacking any appreciable inherent autoxidizable functionality, and
- (e) film-forming condensation polymers modified with acrylate or methacrylate functionality, and
- (3) an effective amount of a polyvalent metal-containing complex or salt that catalyzes the autoxidative curing at components (1) and (2).
