non conductive liquid insulation for very small wires.?

Question

Tape will not work as an electrical insulator on the model i'm building.
Were can I find, or what can be used as a "non" - conductive
electrical insulation to cover the very small wires in this model. It would be easier for my application if it was in a liquid form, similar to a heavy paint that could be applied with a small brush.

Most oils have a low specific heat capacity therefore they usually need to be pumped for semiconductor cooling systems as your temperature difference is extremely small (temperature difference between ambient and the thing your cooling). Water is the ideal in a sealed system as at 4200J/kgC it will remove 42000J of energy for a 10C temperature difference (per kilo). If an oil had a specific heat capacity of 300J/kgC (I believe it would be more like 200-250) then it would only remove 3000J for a 10C temperature difference (per kilo). There are some fluorine compounds out there related to teflon which can work extremely well but they cost an absolute fortune like about £1000-2000 per kilo for the cheap ones! The only way of doing this well is an oil filed pumped system with a fan cooled radiator. There are some commercially available water filled ones as well which are even better but they run the risk of leakage causing potentially lethal electrical problems. The problem with filling the case with oil is that you are just slowing down the rate at which things get hot as you no longer have forced convection from the fans etc, you just have normal convection (you cant run a fan in oil as it will take too much current and blow up from effectively being stalled). If you seriously want to experiment with this you need a 12v centrepetal type pump typically used as a bilge pump in a small boat. These can be used for pumping light oil sometimes (as long as does not have oil soluable seals). The oil can then be pumped through a heat sink on top of the individual chips to take the heat away then put through a radiator with forced air over it to get rid of the heat. You wont be able to do it for less than about £300.

Answer 3

Your choice will depend on the voltage applied to the winding you're trying to insulate, as well as the length of creepage paths you've got.

Some "liquid" insulations will work better than others, since their dielectric is higher. (Basically, you won't need as much thicknes to obtain equivalent protection).

Investigate what's out there ... typical "real world" minimum values quoted by inspectors and safety types are 0.001 inch per volt applied to the conductor.

I'd also investigate how it is applied, and look at what you're building. To adequately insulate a wire, it should probably be "painted" before winding ... and then you need to worry about insulation flexibility (both immediately during manufacture/handling and later during operation).

Answer 4

Similar to what Drew P was mentioning, there is a product called Liquid Electrical Tape that you can buy at home improvement strores in the electrical aisle.

It comes in a metal can and paints on. It dries to a rubbery substance.

That might work.

Answer 5

Some hardware stores sell a 'liquid electrical tape' product, which is simply a liquid rubber with air-activated vulcanization. I've also seen a rubber coating in a spray can (so you can coat chain, I suppose), that might also work for you. I think Lowe's and Home Depot carry both products, and you could probably find them online, also.

Answer 6

There is a liquid rubber adhesive that you can dip metal objects in for protection. It used primarily for metal tools. I'm sorry I don't know the name of it though. You may want to look into that.

Good luck!

Most motors use enamel paint as an insulator.
