Volcanoes in the Coating
We are seeing a defect in one of our smooth gray powder coatings that looks like little volcanoes and is in no repeatable pattern.
Read MoreRequirements for Coating Aluminum
Q. I wish to powder coat a part that is die cast aluminum used for exterior luminaire housings. My question is can you explain the basic processes prior to coating and do I need to specify a special powder or are all powder coating materials rated for the same temperature in use?

Read MorePinholes in Powder
We have a problem with a concentration of fine, dense pinholes in our powder film. The coating is a urethane-polyester that is applied over a part that has been electro-coated. The substrate is sheet metal. The problem is much worse when the powder film is heavier.

The Powder Coating Process
Powder coating is one of the most durable finishes that can be applied to industrial manufactured products, and offers excellent corrosion protection and is very safe because of its lack of volatile organic compounds. To understand the powder coating process you should start with the fundamentals.
WatchMasking Options for Raised Numbers
We have an aluminum casting that is 18 × 12 inches with raised numbers on one edge. I want to powder coat it if I can find an easy way to leave the tops of the lettering bare aluminum.
Read MoreHow to Remove Old Powder from Parts
If a part is already powder coated, how is the powder coat stripped before e-coating, if not by shot blasting? Does it need to go through an oven? Dip in a tank?
Read MorePowder Material Utilization
We do recover some powder, and other colors are low volume, so we do not bother to recover them for reuse. But we are still throwing away a lot of material every year. Any suggestions on how we can get more value out of our powder?
