Certified UL 94 V-0 flame retardant and heat resistant up to 200°C, it fluoresces under UV-A light for easy inspection. Ideal for robotic application, it offers excellent corrosion resistance and allows soldering through the coating or easy removal for repairs. Fully cures in 48 hours, with accelerated heat curing options. ## Description Ideal for high temperature environments. Silicone Conformal Coating (422B) 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. 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 degree C for one hour, but other temperature and time combinations can work well. Heat curing will improve the physical strength of this coating. ROHS Compliant. ## Features - Certified UL 94 V-0 (File# E203094) - Maximum constant service temperature of 200 °C [392 °F] - Fluoresces under UV-A light (blacklight) - Validated for selective robotic coating equipment including PVA and Nordson ASYMTEK - Excellent corrosion resistance—tested in salt spray environment with no oxidation or coating damage - Easy rework and repairs: Solder through the coating or remove with MG Cat.
