摘要:
Disclosed is a filler paste comprising polyurethane resin, chlorinated polyolefin, filler and/or extender, and organic solvents. The filler paste may also include physically drying binders, pigments, and/or rheological additives. Also disclosed is a basecoat containing the filler paste. The basecoat containing the filler paste may be applied directly to polyolefin substrates. After a flash-off period, a basecoat that does not contain the filler paste may be applied on top of the first basecoat layer. After a flash-off period for the second basecoat layer, a clearcoat may be applied and subsequently the applied layers may be cured together, with heating.
