Size Name:1 Ideal for high temperature environments. Silicone ConformalCoating (422B) is a flexible finish product that provides a protective coatingfor printed circuit boards against moisture, corrosion, and thermal shock. Itprotects and insulates electrical and electronic components and assemblies,including generators, motors, transformers, relays, and solenoid coils. Forspraying, liquid can be thinned using M.G. Thinner Cleaner. Thin up to onehalf part thinner to one part coating. Best results will be obtained byapplying to thoroughly cleaned and dried parts or materials. It is essentialthat surfaces be free of any trace of grease or organic substances. At roomtemperature, the product will tack free in approximately 5-7 minutes, and fullcure will be achieved in approximately 48 hours. Curing may be accelerated byapplying moderate heat with either a convection oven or infrared lamps. Werecommend curing in a convection oven at 65 degree C for one hour, but othertemperature and time combinations can work well. Heat curing will improve thephysical strength of this coating. ROHS Compliant.
