RE: Vinyl Ester Resins
Chuck,
I have 6 ports going out of my 3/4hp pump and it works fine. As for the vinyl ester resin, the viscosity is lower than PER but almost everything else is the same. It's more tempermental when it comes to temp/humidity and it takes a little bit longer to B-stage. It's very ideal for vacuum bagging as well as vac infusion.
