DEFINITION

Classification: 427/512

Immersion, partial immersion, spraying, or spin coating utilized (e.g., dipping, etc.):

(under subclass 508) Processes wherein the article or substrate to be coated is (1) submerged or dipped, either partially or wholly, in the coating material (2) positioned to have the coating material projected by mechanical force thereon or (3) conveyed about an axis of rotation, which axis is external of the article or substrate, thus moving in an arc or circle which spreads coating material by centrifugal force.

148, Metal Treatment, for processes wherein reactive coating occurs on the substrate and not externally thereof. Class 427 provides for coating a metal substrate with a resin composition in an immersion bath, wherein metal ions leaching from the metal substrate enter the immersion medium and react or complex externally of the metal substrate to deposit a coating containing an element from the metal substrate.
