It offers exceptional heat resistance up to 200°C, superior corrosion protection, and UV fluorescence for easy inspection. Compatible with robotic coating systems and easy to rework, it’s the go-to solution for professionals demanding reliable, long-lasting electronic protection. ## 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. Review: Excellent conformal coating - Excellent conformal coating. Easy to apply and dries incredibly quickly. We use a syringe to apply it very precisely, and have excellent results. As with any conformal coating, pay attention to specific directions regarding individual layer thickness!! If you apply a thick coating, it is very possible to have bubbles and longer curing times, but we still have achieved very good results thus far. ## 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.
