You should be able to coat faster than you cure, so avoid
standing and waiting for the cure oven.
I personally would prefer to have the two ovens for
greater productivity and easier logistics. Maybe, if you have
limited capital, you can by one oven and try it for a while.
You can always add another oven later.
Treatment for Stainless Steel
Q. I have a requirement for powder coating stainless steel
grade 202 material and I want to know the process, espe-
cially the pretreatment process to prepare the surface for
powder coating.
A. Stainless steel is chemically inert, so there is no perfect
chemical treatment for adhesion of a powder coating.
I suggest you media blast the surface to roughen it for
a good mechanical bond. The media blast creates more
surface and rough pattern that can be very effective.
Application and curing are the same as any other metal
substrate. Make sure the surface is free of dust, dirt and oil
and be sure the part is connected to earth ground. Apply
the appropriate layer of powder and cure according to the
cycle recommended by the supplier of the powder.
