Abstract: Method for forming multilayer coating on an electrodeposition coating of an outer plate part (“OPP”), an inner plate part (“IPP”) and boundary part (“BP”) between the IPP and OPP of an automobile body, including forming a first multilayer-coating on the OPP by coating white intermediate paint (1) (N7 to N9.5) on an electrodeposition coating, coating thereon, by a wet-on-wet technique, white base paint (2) (N7 to N9.5), luster pigment-containing paint (3), and clear paint (4), and then baking; and carrying out at least one of (A) and (B) and thereafter (C) on an IPP and BP (“IPP/BP”), (A) coating (1) in the IPP/BP, prior to (1) in the OPP, (B) coating (2) in the IPP/BP, prior to (2) in the OPP, and (C) coating luster material-containing clear paint (5) in the IPP/BP, prior to (4) in the OPP; wherein the second IPP/BP multilayer-coating is baked simultaneously with the first multilayer-coating.

Abstract: The present invention relates to an intermediate coating composition, which comprises (a) a polyester resin comprising a polyester resin (i) and a polyester resin (ii), (b) a bisphenol type epoxy resin, and (c) an imino group-containing melamine resin, each of which contents of the components (a), (b) and (c) is relative to weight of the resin solid contents in the composition, wherein a weight ratio of the polyester resin (a)/the imino group-containing melamine resin (c) [(a)/(c)] is within a range of 50/50 to 70/30. Therefore, the present invention can provide an intermediate coating composition which can form a multi layered coating film having an excellent chipping resistance, as well as, a method for producing a multi layered coating film by using the intermediate coating composition.

Abstract: An extruder driving apparatus is provided in which a speed change gear mechanism is disposed in a position allowing the speed change gear mechanism to rotate at a much lower rotational speed, whereby a noise level is reduced and a seizing trouble is more surely avoided. The extruder driving apparatus comprises a main motor; a planetary gear mechanism including a torque input portion driven by the main motor and outputting a driving force after reducing a rotational speed of the main motor; an output distributing gear mechanism for distributing a driving force from an output portion of the planetary gear mechanism to a plurality of rotor drive shafts arranged parallel to each other; coupling units for connecting one ends of the rotor drive shafts to a plurality of rotors disposed on the extruder side; and thrust bearings for supporting the other ends of the rotor drive shafts to bear thrust forces imposed from the rotors.
