"We are debating whether to powder coat wood, and if it can be done. Is there a material that will allow us to use our existing equipment? Are there materials that will provide a conductive coating on the surface? The product will be white pine 2x4s, and we are looking for high gloss."
"We have been asked to powder coat steel parts to match an aluminum anodized hinge. So far we have not had much success. Do you think we’re spinning our wheels trying to match a powder to a plating finish? I know that the “chrome” powders that are available really don’t achieve a chrome plating finish. Would I be better off asking the customer to revise the specification to allow us to powder coat both the steel parts and the hinge if they want everything to match?"
"My company has created a revolutionary weighted exercise, weight loss and therapy vest. We have been using a tin plating for our lead weights for the prototype phase, but now that we are preparing for production, we want to find a coating and a coating method that will encapsulate the weights in a thin, durable and possibly flexible coating. What is the best coating and coating method to serve our customers and keep them safe?"
"A few years ago, I spent several days at a very large powder coating manufacturing facility. The plant was doing 'in-mold coating,' in which they took sheets of plastic, placed them in a mold, and closed the mold. I am curious to know if this process is being used elsewhere at this time."
"We used to use a polyester baking enamel for metal office furniture components. This coating had good resistance to 20 rubs with lacquer thinner and MEK [methyl ethyl ketone]. We find that the powder coat we are using doesn’t have similar chemical resistance, and I suspect that most common powders would fall short of baking enamel in this area. What types of powders would give similar chemical performance to the baking enamel, and why aren’t they more commonly used?"
"Is it possible to powder coat plastics? If so, what are the limitations? I have a part that I am trying to have molded, but getting the different colors I need will mean a separate molding operation, more assembly, more inventory, etc. My hope is to have this part molded from polyethylene, and then do either a coating or some other process. Any help would be appreciated."
"What gloss range is best to obtain the full benefits of TGIC superdurable series in powder coatings? Is it over or under 50 degrees? Also, is the integrity and true nature of superdurables compromised when ingredients such as waxes, fillers, matting agents and teflons are added to reduce the gloss?"
Dear Joe, We are a manufacturer of paint racks for plastic parts. One of our automotive customers paints left- and right-hand parts at the same time on the same rack. They occasionally need to paint only one hand, leaving the other hand empty. This causes heavy paint buildup on the hand not being painted. Is there a way to mask the holder so that paint buildup is not a problem?
Dear Joe, I have been told by my distributor that many powders contain an overcure protection additive. What is this additive, and is there a way to find it on an MSDS?
Dear Joe, We recently sent a truckload of galvalume tubing to be powder coated. The finished product appears to have a bumpy surface that looks like fish eyes. This galvalume consists of 43.4% zinc, 55% aluminum and 1.6% silicon. The coating thickness on this product is approx 1.0 mils, while the powder coating thickness is approx 1.1 mils. Could it be the silicon in the matrix of galvalume?
Dear Joe, We recently installed a powder line for automotive parts. Now we would like to install an in-line stripping process for our racks. Can you help us?
Dear Joe,
What are some possible causes for bubbling of powder over e-coat? I am a custom coater who occasionally powder coats an e-coated carbon steel (hot-rolled pickled and oiled) part for a particular customer.
Dear Joe, In polyester/TGIC systems, the Tg is sensitive. Every weight percentage of TGIC reduces the Tg by approximately 1.5 to 2ºC. Why does TGIC reduce the Tg of the coatings
We’ve been having a nightmare with craters in our powder shop over the last few months. We only spray polyesters in our shop. However, one of our neighbors in our industrial park applies a silicone-based military coating. I’m convinced the overspray mist from our neighbor is causing our trouble. Am I correct in my thinking, and what can I do to remedy this situation?
We are starting to manufacture and sell our patent pending, ergonomically adjustable computer workstations. We are interested in the powder coating process for wood substrates such as high-density fiberboard (HDF) that have an even core and face. Do powders for wood substrates still need refrigeration? We would also like to find a powder coater of wood substrates in Northern California or near Reno, NV, that does piece work.
Dear Joe,
We are running an overhead monorail and have two banks of overhead lights in our inspection area. We have tried using a bank of vertical lights, but I am looking to get the best overall lighting setup for a variety of part shapes and configurations.
Dear Joe,
I’m kind of new at this powder coating technology thing and heard an unusual description for powders. One of my operators talked about “winter” powder versus “summer” powder
Dear Joe,
I run a modest powder jobcoating shop. One of my suppliers keeps telling me that I should switch from using hybrids and polyesters to superdurable powders. What are superdurable powders, and should I spend the extra money that these command?
