## Overview

MG Chemicals 422B-340G is a clear silicone conformal coating aerosol designed for high-temperature protection up to 200°C. UL 94 V-0 certified for flame retardancy, it fluoresces under UV-A light for easy inspection and offers excellent corrosion resistance. Ideal for safeguarding printed circuit boards and electronic components, it cures fully in 48 hours and supports easy rework with specialized strippers.

## 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.
