The acetic acid in RTV silicone cures by evaporation, typically in a few hours. Afterward, it's fairly inert. I don't use it for electronics, but the only time I've seen it cause problems is when someone used it as a potting compound and sealed it up in PVC where it couldn't cure and the acid attacked some capacitors. Digi-Key sells watertight connectors that could be used on motor leads, and you might even find some electrical connectors intended for boat trailers. When I'm wiring stepper motors, I just solder the leads and heat shrink them, with a couple of increasingly longer lengths of heat shrink over the bundle for strain relief. It's cheap, low profile, snag resistant, and the electrical connections are reliable if the soldered joints aren't flexing. If they need to flex, crimped connections on stranded wire are much better. I don't need to replace stepper motors very often (hopefully never), and if I do, I can cut open the soldered connections and resolder the leads faster than I can find connectors, crimpers, etc. If I needed the soldered connections to survive coolant, I'd slide the heat shrink over uncured five minute epoxy and shrink the tubing to squeeze out the epoxy and accelerate the epoxy cure, but that's not going to be unsoldered. Repair is by replacement. Leave a little extra cable so you don't need to run a new cable if the motor is replaced. / //My favorite programming language is SOLDER.// // - Steve Ciarcia, Byte //magazine, circa 1979// // / ------------------------------------------------------------------------------ Download BIRT iHub F-Type - The Free Enterprise-Grade BIRT Server from Actuate!
