“I would like to find out about powder coating non-metallic objects such as ceramics. Are there any technical publications on this subject?

“There is a technical publication called Powder Coating; The Complete Finisher’s Handbook that is available through this web site. Click here for more info.”

“Are there any information packets available to send to clients letting them know the benefits of powdercoating? We fabricate custom ornamental iron, most of it is outside, gates, rails, etc. We recommend powder coating to our clients and would like to give them this information.”

” There is a full color informational brochure available from the Powder Coating Institute, Alexandria, VA. Call them and they will be happy to fulfill your request.”

“We utilize a primer/enamel coating system to protect a tractor trailer which is used for transport purposes. These trailers have to be inspected for structural and weld defects such as cracks, stress induced defects, etc. My question is: “Is powder coating a viable candidate to use on a transport trailer and would it lend itself to structural examination better than a standard paint system which masks the defects. Also, does powder coating lend itself spot repair? If powder coating does not fit this application, can you point me in a different direction? Thank you.”

“Powder coatings cannot be easily applied to tractor trailers since the curing process requires the part (in this case a trailer) to be oven baked at 325 degree F...

“I am looking for an alternative to plugging tapped holes prior to powder coating and eliminating this step. I have considered tapping after coating, using self tapping screws and ‘over sizing’ the tapped hole to compensate for the coating thickness. Each of these has their own inherent problems. What is the common practice in the industry? Thanks.”

“You have mentioned both corrective actions for tapped holes. Masking with plugs or post machining after coating. There are no other alternatives that can be employed on a production...
