    Hi, Im looking for the name of the light brown glue used to hold down Caps and on wire to
    relief the strain,
    I don’t wont to use hot glue

    does that brown stuff last years ?
    if not what else could I use ?

    I just want it for wire relief

    hoping to get it at RS components

    cheers

    Don't know what 'brown glue' you're referring to.
    A lot of what you need will depend on the heat the board is exposed to.
    No necessarily the heat of the components you intend to glue-down.
    Is the circuit going to be in a cabinet or enclosure that will get hot?

    Just checked..

    We use something called Dow Corning 744 at work.
    I think RS carries that brand too, maybe you could get that.

    That's what I use, RTV or Silicone rubber caulk,
    It is also easy to remove, should the need be to replace a component.

    I'll mention, a lot of the circuits you see coming out of China, they are allowed to use whatever they want (no chemical MSDS requirements). Your brown glue might just be what is cheap and easy to get wherever your controllers were manufactured.

    What's so speciel about that brown stuff? I mean, we are talking about securing some wires.
    Now you want to start mixing something. Why not just use, an off-the-shelf solution, that's made for just these sort of things?

    The stuff i talked about earlier. IS used in production (In the end product) on capacitors, inductors, varistors, whatever. I see no reason it cant work on holding down a wire. The place I work ship millions of products every month with that stuff in them.

    Edit: davenn beat me to it :eek:

    I dont like RTV,
    It does not last long once the tube has been open/pieced also its not that cheap here
    Ive used hot glue before and not easy if you want to service/work on the item again and remove

    I understand why RTV is used in production but I might only use it 4 times a year maybe, not practical for me.

    If no one knows what the brown stuff is called thats fine

    yes that is a valid response
    so use white or clear silicone sealer ... pretty cheap in small tubes from your fav hardware store



    that's also valid .... personally I wouldn't use hot glue, unless I had absolutely nothing else available
