Conformal Coating - Silicone, w/UV Indicator 2Oz


Ideal for high temperature environments. Silicone Conformal Coating (422C) is a flexible finish product that provides a protective coating for printed circuit boards against moisture, corrosion, and thermal shock. It protects and insulates electrical and electronic components and assemblies, including generators, motors, transformers, relays, and solenoid coils. For spraying, liquid can be thinned using M.G. Thinner Cleaner. Thin up to one half part thinner to one part coating. Also available in a micro tip pen format.


Spray an even coat with a minimum application of .048 grams per square centimeter. Application measurements can be achieved by first weighing the can, then spraying an even coat, then reweighing the can. Knowing the dimensions of your board, one can calculate as to whether your application is within certified limits. This method will give you maximum surface area coverage of 7080 cm2 (7.6 ft2). Best results will be obtained by applying to thoroughly cleaned and dried parts or materials. It is essential that surfaces be free of any trace of grease or organic substances.

At room temperature, the product will tack free in approximately 5-7 minutes, and full cure will be achieved in approximately 48 hours.

Curing may be accelerated by applying moderate heat with either a convection oven or infrared lamps. We recommend curing in a convection oven at 65°C (149°F) for one hour, but other temperature and time combinations can work well. Heat curing will improve the physical strength of this coating.
