ABSTRACT:
The present coating system (100) provides a multilayer coating apparatus for coating an object (112). The multilayer coating apparatus includes a slide hopper (116, 140). The slide hopper includes a main body (116, 140), the main body essentially including a plurality of separate cavities (118, 120, 122) for receiving coating materials, a plurality of separate slots (124, 126, 128) in communication with the corresponding cavities, and a plurality of separate projection portions (130, 132, 134) formed on the slide hopper, the projection portions each having a substantially sloping slide surface (131, 133, 135) configured for allowing the particular coating material exiting from the slot to directly flow onto the object.
