Q. I am interested in coating PVC foam boards with paint. I heard that vacuum coating is a process that will work for this application. Can you direct me to a company that can either supply the equipment to vacuum coat, or provide the service to vacuum coat? E.S.

A. Simply stated, in this process, the moving product passes through an application chamber that is evacuated. Both ends of the chamber are sealed except for openings the same shape as the cross section of the product. The paint is pumped into the chamber completely surrounding the product. Owing to the relationship between the entrance and exit openings and the product the paint film thickness is maintained automatically. It should work for foam board components. Suppliers of the coating equipment can be found through a web search for “vacuum coating” or by visiting the Society of Vacuum Coaters’s website svc.org.
