What paint finish most closely resembles LDPE?

Hello

What paint finish most closely resembles smooth LDPE? (Low Density PolyEthylene)

I have made some prototype using 3D Printing using SLS of Nylon 12 material (Fine Polyamide PA 2200).
Apparently sintered Nylon sucks up paint surprisingly well. However I need a paint that has the mechanical properties of LDPE. In particular I need a paint finish that is slippery with a similarly low coefficient of friction.

Any suggestions?

So simple powder-coating won't cut it? I think the material used for powdercoating is some sort of polymer, like polyurethane or polyester. I've also seen things dip-coated in PVC and PE.

So maybe you can get a part coated with polyethylene via the dip-coating of powder-coating methods.

PTFE, PFA, FEP? It's going to depend on what you're specifying the coating for. Some of these don't play well at high temperatures.

I suggest you contact paint supplier who know better than an engineer here
