1. A metallic coating composition comprising:

  • 40 to 80 weight percent (wt%) of a non-functionalized propylene base polymer, wherein the non-functionalized propylene base polymer has a crystalline melting point of 100 ℃

    to 230 ℃

    measured using differential scanning calorimetry;

    5 to 9 wt% of a polymeric coupling agent, wherein the polymeric coupling agent has an acid number of less than 100 and a melt viscosity of less than 80000 centipoise (cP) at 150 ℃

    ;

    10 to 30 weight percent of a polymeric stabilizer having an acid number equal to or greater than 100;

    5 to 35 wt% of a polymeric performance improver, wherein the polymeric performance improver has a melt index value of less than 100;

    a neutralizing agent that partially or fully neutralizes the polymeric stabilizer; and

    a fluid medium, wherein the value% is a value based on the total weight of the non-functionalized propylene matrix polymer, the polymeric coupling agent, the polymeric stabilizer, and the polymeric performance improver of the coating composition and totaling 100 wt%.
