Bit of a Random one this
Does anyone know of a substance thats easily applyable, waterproof but not conductive & is not likey to melt plastic / solder etc
What are you hatching up!?
Not sure about the conductivity side of things but isn't HEAVY grease something that's cheap and easily available in large quantities?
I'm thinking of the waterproof sludge type that sticks like watchamacallit on the blanket NOT the more commonly used LM or Graphite Grease...
Just a thought!

Sorry to differ, but silicone sealant gives off acetic acid as it cures, which will eventually corrode the board and components.Bathroom/standard housework Silicone sealant in a tube that you'd use for sealing a loose headlight glass will do that no probs!!
What you need is a conformal coating - widely used and designed for just this application - protects against vibration too.
Didn't realise this. Do you know whether acrylic sealant has a similar effect?dnsey wrote:silicone sealant gives off acetic acid as it cures, which will eventually corrode the board and components.

If a silicone isn't appropriate because of the aceitic acid, there are alternatives. There are numerous latex based sealants (is silkaflex latex?), various modified silicones etc. One I've used is "Nail and Seal", I'm not sure exactly what it is, but it doesn't smell of aceitic acid. It's particularly good for sealing things because it will stick to a variety of materials that silicone won't, it even sticks to some plastics that are "difficult" to glue. It isnt expensive, stays rubbery when cured and it works as an effective glue (holding the soles onto a pair of my trainers!).
