I would recommend the following chemistries: Zestron Vigon SC200... Good but very $$$$ (703) 589-1198 Vertex (sold by Petrofirm and Alpha Metals)... Won't last as long as Zestron but must less $$$ (904) 261-8286 Kyzen... Also very good (800) 84

We are currently fighting a dross battle on our non-inerted waves. We are currently using a bar solder that barely meets QQS-571 for Alloy/Impurity. Is anybody using HI FLO in a non inerted wave? Do you see a measureable decrease in dross? Thanks

We have two batch systems here. The systems have worked very well but the interior stainless steel is very dull. We are running a DI based open loop system for cleaning primarily a WS flux. In special cases we have used ArmaKleen E-2001 and Alpha

I just realized my last posting has some incorrect references. Blame it on last nights sour mash! (St. Pauli girl didn't respond!) The article I referenced was found at the AlphaMetals website, a study done for AlledSignal, in conjunction with Churc
