We are producer of electronic blocks. We are use for capsulation our blocks silicone RTV627, but earlier we was using silicone CRTV-6405. We want find provider silicones CRTV-6405. In month we are use up 400-500 kilogram of silicones. Our firm locat

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

we encounter bubbles on silicone coating after oven curing.what to do to avoid bubbles?

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

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

IMHO I would avoid sprayed silicones like the plague. They can travel around your facility and cause solder wetting issues that you will never know the root cause for. Also found this e-drive article on using silicones around motors and relays. Loo

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

Don't think CRTV-6405 is produced any longer. Try GE Silicones Technical Support 800-255-8886. We have no relationship, nor receive benefit from the company referenced above.

Hose and/or Dave, Please elaborate of how the silicone can affect soldering. Material itself or fumes?
