Gorilla snot ?
Anybody know a brand, model, or generic type of glue that is sometimes
used to secure audio or RF cable.plugs to pcb-mounted sockets, such as on Mipro portable PA speakers. I do have some non-corrosive silicone, but the stuff I am looking for is nearly clear (slightly yellow-brown) and thick and rubbery/sticky. Presumably does not take long to get to that state from application, unlike the silicone I have which takes upwards of 8 hours to cure. geoff |

A bit like the stuff they use to adhere credit cards to paper with for postage. geoff |

It's usually two part - matrix and catalyst. That's different from the stuff that smells like acetic acid and takes a long time. The phrase "sometimes used to secure audio or RF cable.plugs to pcb-mounted sockets." worries me, though. If it needs to NEVER EVER come off, EVER, then there's always JB Weld. -- Les Cargill |

Needs to be relatively easily to remove. And this particular stuff re-gloops together again with mild finger-tip working. geoff |

I think I know which goop you're talking about, but I've never seen it in the application I think you're describing. Is this an idea that you have, or have you actually seen it in use - and if so, where and how? I can't quite figure out what you're trying to do, other than to secure a connector that wasn't designed for the service to which you're putting it. -- "Today's production equipment is IT based and cannot be operated without a passing knowledge of computing, although it seems that it can be operated without a passing knowledge of audio" - John Watkinson Drop by http://mikeriversaudio.wordpress.com now and then |

There are various makes of Room Temperature Vulcanizing silicone. It's usually two part - matrix and catalyst. That's different from the stuff that smells like acetic acid and takes a long time. There is also an electronics grade which uses alcohol or boric acid instead and does not cause corrosion or smell like vinegar but otherwise behaves like bathtub caulking. And, a lot of equipment now is assembled with hot melt glue, because it is very, very fast. But I think the stuff Geoff is talking about is a kind of urethane contact cement. Techs here call it by a name I won't repeat in polite company. I don't have a source for it, but 3M 08061 is usable and available cheaply at your local auto parts store. JB Weld Filled epoxy, equivalent to Araldite in the UK. --scott -- "C'est un Nagra. C'est suisse, et tres, tres precis." |

Used in equipment to additionally reinforce tension-only held connector types that are in devices potentially subject to vibration. Is designed to be easily removable, and can be re-joined as previously described. Not hard stuff like the cement often used to support component like large electrolytic, not non-corrosive silicone, and not anti-tamper lacquer. I have most recently seen it in internal rf coaxial antenna cables-to-connectors in a Mipro self-powered speaker. Looks like it comes out of a tube as a globby lump, and firms up without any significant sagging, and never goes fully hard. geoff |
