Question: I am doing research on different ways to paint hubcaps (ABS plastic and Teflon®). Currently, we use only liquid paint but are looking into the possibility of using powder paint as an alternative.
I am doing research on different ways to paint hubcaps (ABS plastic and Teflon®). Currently, we use only liquid paint but are looking into the possibility of using powder paint as an alternative. Is there a method of powder coating that would be applicable here and would not melt the hubcap? Where do you suggest I go to find out more about the possibilities and limitations of such a process? J. D.
Powder coating of certain plastic substrate has been performed for the last 5+ years. The only restriction is that the plastic substrate must be able to withstand 250°F to melt the powder coating onto the surface prior to UV curing. If your hubcaps can withstand 250°F without melting, then you should continue your investigation into powder coatings. If your plastic falls short of this temperature requirement, then look elsewhere for your coating needs.
Masking is employed in most any metal finishing operation where only a specifically defined area of the surface of a part must be exposed to a process. Conversely, masking may be employed on a surface where treatment is either not required or must be avoided. This article covers the many aspects of masking for metal finishing, including applications, methods and the various types of masking employed.
