Silicone conformal coating provides excellent protection in a very wide temperature range. SR provides good chemical resistance, moisture and salt spray resistance, and is very flexible. Silicone conformal coating isn’t abrasion resistant because of its rubbery nature, but that property does make it resilient against vibrational stresses. Silicone coatings are commonly used in high humidity environments, like outdoor signage. 

Fine-L-Kote SR is available in 2 viscosities:
Standard - 4-10cps

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