<p>A method of coating some or all of an underbody of a vehicle on a production line, comprising applying a polymeric coating powder to the underbody or the vehicle body part, sintering the powder to the underbody or the vehicle body part. The polymeric coating powder includes a mixture comprising a polyolefin having polar functionality, and one or more ethylene α-olefin copolymers, the mixture having a melt flow index greater than 15g/10 minutes (2.16 kg, 190 °C). The polymeric coating powder preferably has a melt flow index greater than 20 g/10 minutes. The ethylene α-olefin copolymer should contain at least 50 mole % ethylene. The α-olefin co-monomer may be chosen from propylene, butene, hexene or octene. The polymer having polar functionality may be a copolymer of ethylene with at least one polar monomer.</p> |
