Wow, I cut first cut my teeth in the Industrial motor control industry. My 1st company made motor control products like variable speed drives, solid state overload relays, soft starts, etc. and in our shop, we used nothing BUT Dow Corning silicone p

Material, fumes, cured or uncured, all are suspect. Silicone gets on an operator's hands, that operator handles components ( even a day or more later ) silicone is transferred to the solder connections = contamination. Process and workcell control

Hello to all out there, We're considering CC process,and would like to know some defferences between SSC3 of Electrolube and Humiseal 1B73, yes,I know that SSC3 is silicone one,and Humiseal 1B73 is solvent based acrylic as well as other basic propert

We have PVA 350 benchtop dispensing equipement with humiseal 1A33 CC material. is there any moisture measurement process in conformal coating material?

We are developing a new product that requires conformal coating on the motor controller. We selected a silicone based conformal coat due to its ease of use. There has been disagreement among engineers as to its impact on the motor. We have contact

We allow no silicone in our shop, because they ruin solderability.

Especially VCM - volatile condensable materials. Strictly verboten around optics.

We use nothing but silicones and have for at least the last 7 years. We don't have relays, but we do have motors. No issues with soldering, but our lines are constructed such that the last solder operation is a good distance from the coating or pot

I'm not that concerned about the solderability of the motor. Our customer is concerned about the outgassing of the conformal coat effecting the motor brushes. Silicone will break down into SiO2 and SiC will result from a spark between the brushes a
