Abstract

A coating composition includes: (a) (i) a thiol functional compound and (ii) an ethylenically unsaturated compound reactive with (i); (b) a catalyst that catalyzes a reaction between (i) and (ii); and (c) an odor masking agent that masks an odor of at least (i) the thiol functional compound. A method of forming the coating is also included.

Description

technical field [0001] The present invention relates to coating compositions containing odor control agents and methods of forming coatings from such coating compositions. Background technique [0002] Coatings formed from compositions containing thiol functional compounds provide various benefits including fast on-demand cure, good coating appearance, and other desirable properties. Coatings formed from compositions containing thiol-functional compounds also provide an alternative to other types of coatings, such as coatings formed from isocyanate-functional compounds. Although compositions containing thiol functional compounds offer many benefits, these compositions often have an unpleasant odor. Compositions containing mercaptans are often avoided due to their strong, unpleasant odor. Accordingly, it would be desirable to provide alcohol-based coating compositions that have a pleasant sulfur odor and form coatings that have good appearance and other desirable properties...
