Patent abstract
A method of applying a curable composition to a substrate is disclosed. The composition comprises a polyene and a active hydrogen-containing compound that are capable of undergoing a Michael Addition reaction. The reaction is conducted in the presence of a tertiary phosphine catalyst. The components of the composition are sprayed in separate streams whereby the streams overlap prior to contacting the substrate and the composition cures quickly on the substrate.
