Its UV-A fluorescence enables easy inspection, while compatibility with robotic applicators ensures precision. Fast drying and easy rework make it the go-to choice for safeguarding sensitive circuit boards in demanding industrial environments. ## Description MG Chemicals silicone conformal coating is a flexible finish product that provides a protective coating for printed circuit boards against moisture, corrosion, and thermal shock. Ideal for high temperature environments. 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.
