Priming – UV Light Cured and Sanded
- Ultraviolet curing lamps for complete fill
- No volatile emissions for an environmentally friendly finish
- 10-station sander with 400 grit surface sandpaper
Brooke: George, I’m seeing a lot of white moldings here. I thought O’Hair only sold Shutter Panels that are unfinished.
George: That’s correct, but we do have a primed surface so that our customers have a minimal amount of surface preparation on their painted product. Actually the market is 90% painted.
Brooke: So the moldings are primed, and then you make the shutter panels out of them. How are the moldings primed?
George: We begin with a flat line that is 3 roller coaters in tandem.
Brooke: What are the bright lights all about?
George: Those are UltraViolet curing lamps. Our primer is a 100% solids UV curable primer. When it comes into contact with the UV radiation from the lamps, it cures to be 100% solid.
We have no solvents and no water in our primer.
Brooke: That must sound like strange stuff to some.
George: You definitely wouldn’t want to use UVs around your home. However, they have some great advantages. They provide an excellent moisture barrier and a very complete fill. There are also no volatile emissions involved so we’re environmentally friendly. They are great for straight-line production.
Brooke: George, I don’t see any sanding at the end. What about grain raise?
George:It’s minimal with UV, but we do have sanding in our vacuum line.
Brooke: Let’s go take a look at that.
George: The flat line coats the flat surfaces. The vacuum line coats the entire profile in a single file motion.
Brooke: And the sanding equipment?
George: We have profile sanders at the beginning and the end of the vacuum line. At the end we have a 10-station sander made up of felts and wheels. We finish with a 400 grit surface.
Brooke: Very smooth!
George: Smooth enough to make components, and that’s our next stop!
