Tested, Flame Class 94 V-0
Ideal for high temperature environments. Silicone Conformal coating
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.
Directions of Use
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 cm
(7.6 ft
).
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 30
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.
