Spraying UV curable finish3/9
We have potential use automating for two different product lines. One for moulding and one for flooring.
However, at this time neither one really justifies any kind of automated line on its own. We currently spray our moulding (conventional, water based) by hand, and send out our flooring to a roll coat UV line.
If it was/is feasible to spray UV curable finish on flooring, it might be feasible to take this next step and get a through feed multi gun spray cabinet, and add a UV light curing station behind it for the flooring (maybe for moulding too).
I'm sure there's a reason that flooring is usually roll coated. Is it just because that's the most sensible way of doing it if all you're doing is flat? Or is there some reason that spraying is not a good idea?
I realize that with a roll coat system you have 100% transfer rate and it will be lower for a spray setup, but I could give you some efficiency to save 10s of thousands if the end result were similar.
Thin the roll coating with proper solvent, more than likely acetone and spray away. May have to allow extra flash off though.
Do not thin the roll coat UV and spray it. UV coatings are a reactive product and have hazardous raw materials in them that can harm you if you breath them in. You must have a complete body suit because your skin can also absorb the reactive raw material.
Thanks Jeff, that makes sense, as I know people have gotten badly burned after going outside after getting the material on their skin. Didn't think about the likelihood of atomized material getting on your skin.
wow....... Take any advise left here with a grain of salt.... Dude unless you know what your doing do not spew dangerous suggestions with chemicals out there. You cannot reduce and spray 97+% solids by reducing it.... especially not with acetone...lol not only is that far fetched its down right idiotic to even suggest it. I run a full UV coating line with heeseman sanders inline in our shop... we have 2 automated linear sprayers also... We have 8 full time hand spray open faced booths.. we spray literally just about every type of coating out there for all kinds of custom architectural projects.. there is a world of chemistry and resin difference between sprayable uv and roll coat uv.... neither you want to "Experiment" with.. Please use finishing chemicals and coatings for what they are intended to do and go by the data sheets on how to do it and you wont get burned... be smart folks and remember not everybody that has suggestions here is a professional. some of these folks are know it all hobbyist.
