Ask Joe Powder (New) | ||
![]() "Ask Joe Powder" "Ask Joe Powder" is a question and answer column authored by Kevin Biller of the Powder Coating Research Group. Mr. Biller has over 30 years experience formulating and manufacturing powder coatings. He welcomes your questions regarding powder coating technology. Please write to: askjoepowder@yahoo.com Kevin Biller The Powder Coating Research Group 4419 Brookpark Road Cleveland, OH 44134 614-354-1198 www.powdercoatingresearch.com Hello Joe, I read your article about out gassing on zinc die castings. I have a few questions about this, if I could. - Does this happen with aluminum die castings as well? - What is the result of the out gassing, I envision a little "crater" on the surface of the part. - You recommend driving the part temperature above the powder cure temperature which is typically 400 degrees F. How much higher than the cure temperature should you take the part to and for how long; i.e.: is there a recommended soak time at the elevated temperature? Thanks for the help Joe, Mike Blumberg Hello Mike, Yes this phenomenon occurs with aluminum castings as well as zinc die cast parts. My experience has been that the aluminum castings generally have less porosity than the zinc ones and hence less outgassing issues. As for the pre-bake - a long soak is not needed. Getting the part up to a temperature slightly above the powder cure temperature is sufficient. Using a lower temperature cure powder would help a lot. I suggest trying a 325F bake product. They offer a reasonable compromise of lower energy requirement without a serious concern for storage stability. Powders that cure at sub-300F temperatures usually require more careful handling and have shorter shelf life. Let me know if this solves your problem. Best Regards, Joe Powder Joe, We do auto restoration and are asked to provide high shine, chrome like powder for parts like intake manifolds, wheels, etc. What is the brand and number of the brightest powder that you are aware of? We have been using a "Tiger" product with a clear coat - the clear protects the base from oxidation. The clear knocks the shine down significantly. Are there any techniques on applying clear that would help? Thank you, J. Michael King Dear Mike, Finding a chrome-look seems to be the Holy Grail in powder coating technology. All of us powder coating formulators have the same aluminum flakes available to create a shiny chrome-like (not chrome-look) powder. We use leafing aluminums to provide the patina-like sheen, but we have never approached the brightness of a plated surface. Using a clearcoat however should enhance the brightness not diminish it. It's important to marry the clearcoat with the silver metallic basecoat. Using the same chemistry is a good start. It's also wise to fully cure the basecoat before applying the clearcoat. Any movement or emission of volatiles from the basecoat due to undercure will reduce the clarity and brightness of the clearcoat. It's also vital to provide the highest smoothness of the basecoat otherwise the clearcoat will mirror the texture of the basecoat. Getting a smooth basecoat means (1) using a smooth powder to begin with, (2) applying the recommended thickness - too thin will create texture and (3) laying down an even coat - avoid electrostatic "pop-off" by moderate gun voltage and distance to the part. The same care taken with applying the basecoat applies to laying down the clear topcoat. One very important issue is to ensure that you have a very good ground (earth) to the part you are coating. This is especially important when applying a powder to an already coated part. Poor grounding will result in uneven and thin deposition of powder. It is wise to reduce the current and kV's so you don't build up too much charge on the part surface. Too much charge causes back-ionization and the physical "pop-off" of powder. This reduces the smoothness and brightness of the finish. As for recommending a supplier of the brightest chrome-like finish - I think most powder suppliers have comparable technology. There is a technology recently pioneered that provides a chrome-like finish using powder coating. At least three companies use it. It consists of a multi-layer process beginning with a very smooth powder basecoat which is cured completely. The coated part is then introduced into a vacuum metallizing chamber which deposits an extremely thin layer of metal - typically aluminum. This aluminum layer is incredibly bright but will oxidize and lose brightness within minutes. Consequently the next step is the application of a very smooth powder clearcoat typically an automotive grade acrylic. This creates the closest approximation to a chrome finish using a powder. Let me know if you have any more questions. Best Regards, Joe Powder Joe, We refurbish a large volume of metal parts that have dents in them. I think we have tried most if not all the high temperature fillers, with poor results. These fillers are very expensive and have adhesion problems and bubbles forming in the finished coating. We have used "Thermobond-3", "High Temp Lab-Metal", etc. We have had best results using "All-Metal" a high metal content, regular temp. body filler. We use thin coats allowing 24 hours to dry between coats and the we cure it out around 275 Deg.F. This is O.K. but it expensive and very time consuming. Are you aware of any products or techniques that will help us? Thank you, Mike King Mike, Repairing dents in parts can be a nightmare. And I agree most high temperature fillers don't always work. Here's what I would do. Apply the filler as recommended by the filler manufacturer. They usually want you to apply no more than a quarter inch (6mm) at a time then let the material air-dry for 24 hrs. They then recommend curing the material before coating or applying another layer. I would bake the material at a relatively high temperature to drive out any volatiles that may be present in the filler. 425F (218C) for 1 hour is where I would start. Alternately you can try the lower temperature fillers however I would only use something that is cured at a temperature higher than the powder I subsequently would be applying. Let me know if this helps. Best Regards, Joe Powder Joe Powder has over 30 years experience in powder coating formulating, manufacturing and troubleshooting.
