Drew & List;

How much recycled material are you running? It appears that our powder
picks up more of a static charge after it has been recycled and sifted.
Therefore, we have started to spray our roller down with an anti-static
agent (Static Guard) before our Duraform and Duraform GF builds.

DTM recommends this in their documentation for running SOMOS, but we thought
we would try it with Duraform as well. Boy, what a significant performance
increase on taller parts because the powder does not collect on the roller
or wiper nearly as much. Anyone else try this technique?
