Abstract
A process for the application of aqueous multi-component coating compositions comprising at least two components and are prepared by premixing said components. The mixture is applied to a substrate using high-speed rotary atomization, wherein the high-speed rotary atomizer(s) is operated with a circumferential velocity of the spray edge(s) in the range of 10,000 to 25,000 m/min.
Claims9
A process for the application of an aqueous multi-component coating composition comprising the steps of:
- (a) preparing a premix of an aqueous multi-component coating composition comprising at least two components;
- (b) high-speed rotary atomizing the premixture using at least one high-speed rotary atomizer, each having one spray edge, wherein each spray edge has a circumferential velocity ranging from 10,000 to 25,000 m/min;
- and
- (c) applying the atomized premixture to a substrate.
