How to Powder Coat Aluminum – Aluminum Powder Coating


Powder Coat Aluminum
Comparing with conventional paint,powder coating is much more durable and is commonly applied on substrate parts that will be long term exposed to tough environments.That maybe worthwhile to DIY if there are lots of aluminum parts around you required for powder coating.It is no more difficult to buy a powder coating gun on your market than spraying paint .


1.Clean the part completely,removing off any paint,dirt or oil .
Make sure that any components not to be coated (such as O-rings or seals) have been removed.

2.Mask any area of the part not be coated using high-temperature tape. For blocking off holes, purchase reusable silicone plugs that press into the hole.
Mask large areas by taping on a piece of aluminum foil.

3.Set the part on a wire rack or hang it from a metal hook.
Fill the gun’s powder container with powder no more than 1/3 full.Connect the gun’s ground clip to the rack.

4.Spray the part with powder, coating it evenly and completely.
For most parts, only one coat will be necessary.

5.Preheat the oven to bake.
Insert the part into the oven being careful not to bump the part or touch the coating.
Consult the documentation for your coating powder about necessary temperature and curing time.

6.Remove the part from the oven and let it cool. Remove any masking tape or plugs.

Make sure the gun is plugged into a properly grounded outlet.The gun cannot work without a ground connection. For more detals about powder coat aluminum process,please feel free to contact us
