Abstract:
A process for the production of a multi-layer coating on the surfaces of an electrically conductive three dimensional object comprising the following steps:(1) applying at least one primer layer to the surfaces of the object by electrodeposition from an electrodeposition coating agent (I); (2) at least partially curing exclusively by the action of near infra-red radiation substantially only the primer layer on the surfaces of the object exposed to said radiation to form a primer layer that is electrically conductive in the at least partially cured state; (3) applying an additional layer of coating by electrodeposition from an electrodeposition coating agent (II) which is different from electrodeposition coating agent (I) over the primer layer applied in step (1) that is at least partially cured; and (4) curing both the primer layer and the additional layer on the object to form the multilayer coating on the object.
