Have been looking for a while for something to insulate back sides of motherboards etc for a while besides vaseline and this stuff fits the bill in every category.
CRC Urethane Seal Coat
Product Features
- High dielectric strength 1300 volts/mil, high surface and volume resistivity make it ideal for electrical/electronics applications
- Effective temperature range of -90 to 250 degrees F
- Dries quickly to a hard, durable, flexible and non-conductive film
- Abrasion resistant insulator for electrical and electronic equipment and components
- Allows easy visualization of circuit paths on PC boards
Thought I would try it on the backside of my 32m card first.
1 thick coat and dries fully within 12 hours, doesnt crack or web when I bend the pcb a little bit and not easily flaked off.
You can kind of see the thickness near the PCI-E fingers which were taped off.
Used primarily to seal and prevent shorts with water but seems to bead it up nicely as well.
Will apply to a mobo next and update how it stands up to ln2
