Polypropylene composition suitable for primerless painting

Polypropylene composition (C), the polypropylene composition (C) comprising:

• (a) 40.0 to 80.0 wt. %, based on the total weight of the composition, of a propylene copolymer (R-PP) wherein the propylene copolymer (R-PP) comprises two fractions, a first propylene copolymer fraction (R-PP1) and a second propylene copolymer fraction (R-PP2), said first propylene copolymer fraction (R-PP1) differs from said second propylene copolymer fraction (R-PP2) in the comonomer content;
• wherein the propylene copolymer (R-PP) having
• (a1) a comonomer content in the range of 1.5 to 8.0 wt. %, and
• (a2) a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 5.0 to 100.0 g/10 min, and
• wherein the propylene copolymer (R-PP) has:
• (a3) a glass transition temperature in the range of −12 to +2° C.;
• and/or
• (a4) no glass transition temperature below −20° C.;
• and
• (b) 20.0 to 40.0 wt. %, based on the total weight of the composition, of a mineral filler (F) being selected from the group consisting of talcum, wollastonite, kaolin, and mica,
• wherein the polypropylene composition (C) has a melt flow rate MFR2 (230° C.) measured according to ISO 1133 in the range of 5.0 to 45.0 g/10 min.
