Keller set out to develop a sustainable process which incorporates a dry separation system for wet paint overspray.

Keep on Truckin’ with the Right Coatings
The Raymond Corporation knew it wanted the latest technology available. The question was a little more complex: liquid or powder for its coating applications.
Read MoreA New Wrinkle
The same paint does not produce the same wrinkle texture when applied by the vendors—and we have tried different vendors. The only difference I can see is that we use electrically-fired ovens and they use gas-fired ovens. What do you think about this?
