Urethane conformal coating is known for its excellent moisture and chemical resistance. They are also very abrasion resistant. Due to this and their solvent resistance, they are also very difficult to remove. Like silicone, full removal generally requires specialized solvents, long soak time, and agitation like from a brush or an ultrasonic bath. Urethane conformal coating is commonly specified for aerospace applications where exposure to fuel vapors is a common concern.

FAQ's

What is the difference between dielectric strength and dielectric withstand voltage?

The dielectric strength is material intrinsic property and withstand voltage is surface property which depend on thickness of the material. They can be slightly different for thicker materials, but for conformal coating, the two numbers should be very close or the same. That is because we test coating at 3-5 mils thickness, calculate, then report the value per mil.

What type of UV light / black light should I use for QC inspection of the final conformal coating?

Conformal coating with UV tracer can be inspected with any typical UV lamp which has wavelength of 320-380 nm.

What solvent can I use to thin this conformal coating?

Toluene can be used as a thinning agent. Make sure it is anhydrous, so contains as little moisture as possible.
