Physical and chemical properties of primerless waterborne paint for composite polypropylene instrument panel were investigated. Primerless waterborne paint with 30% of polyolefin modified acryl emulsion, 15% of alkyl methacrylate emulsion, 3% of crosslinked polymethacrylate bead, 2% of amide modified polyethylene wax had good adhesion properties onto PP substrate without adhesion promoter and showed better properties on long tenn reliability test. In production line test, IR curing condition was insufficient for waterborne paint due to high latent heat of evaporation and complicated feature of instrument panel. Waterborne primerless paint was sensitive to painting environment compared with solventborne paint.
