The regular Silicone RTV that contains acetic acid will disolve your copper
or tinned braid or even center conductor in a month but will probably not
harm the jacket

They make an acid free version of the silicone RTV thats good for direct
waterproofing of copper and connectors. Coat your connectors with this after
assembly then tape it and it lasts for years!

It can be found in some automotive parts stores as well...sure beats black
tape and pretty much anything from Radio shack

Its also referenced in a lot of Motorolla and Harris equipment white
pages....It's really great stuff!

Hello:

Is it safe to use the typical GE RTV silicones against a Polyethylene (PE)
coax outer jacket ?

I know the RTV's use some type of acid (acetic ?) to cure the stuff, and I
was wondering if
anyone might have any first hand experience if there is any kind of
interaction with a coax outer jacket ?

Thanks,
Bob
