Abstract: Carbon Michael cure is effected by combining a tertiary amine component, an epoxide component, a component with Michael Reaction-active methylene groups, and a component with Michael Reaction-active alkene groups. The tertiary amine and epoxy components are combined during or shortly before combination of all components. Two-pack ambient cure coatings using this method have improved combinations of pot life, early cure, gloss, and ultimate cure. Improved resistance to water is achieved when the epoxide component and/or the tertiary amine component are pre-reacted with a Michael Reaction-active component during cure. Low cost and hazard, together with good cure and resistance properties are achieved when the Michael Reaction-active alkene groups are from a particular class of maleic/fumaric polyesters. When the methylene groups are acetoacetate moieties, low colour is achieved when the alkene groups are acryloxypropionate moieties, or when the alkene groups are acrylate moieties and the molar ratio of alkene moieties to acetoacetate moieties is greater than 1.5. Lower colour is achieved with fumarate and acrylate when the methylene groups are malonate rather than acetoacetate.

Abstract: The disclosure relates to a powder flow control valve comprising a nozzle (33) formed from a material such as high density polythene having an upper frusto-conical section (33a) which converges towards the lower end of the nozzle and terminates in a cylindrical section (33b). The nozzle is encircled by a plenum chamber (24) to which sources of vacuum and air pressure are selectively connectable through a pneumatic control system (14). When vacuum is connected to the plenum chamber, the resulting pressure drop across the wall of the porous nozzle causes powder flowing through the nozzle to consolidate in the nozzle and terminate the flow. When air pressure is applied to the plenum chamber, the resulting pressure rise across the boundary surface accelerates powder flow through the nozzle. The control means is arranged to establish air pressure in the plenum chamber to initiate opening of the valve and flow through the valve and, after a pre-determined time, to terminate the air pressure supply and allow powder to flow under gravity through the nozzle before flow is terminated when a pre-determined quantity of powder has been delivered by the nozzle by applying vacuum to the plenum chamber.
