Product Details

The 422B Silicone Modified Conformal Coating is a clear and flexible coating that is ideal for protecting electronic circuits in high temperature environments or applications requiring extreme flexibility. It protects against moisture, dirt, dust, and other particulates, and thus avoids corrosion of electronic components. It also insulates against high-voltage arcing, shorts, and static discharges. As well, it protects against thermal shock and puts very little stress on components during temperature cycling. Compared to other typical silicones, the 422B is a one-part, acrylated silicone which makes it is easier to apply, remove, and rework. Also, it has a faster cure time and a much longer shelf life. It is available in both aerosol, liquid, and pen form and may be applied by spraying, dipping, or brushing. The 422B protective coating is UL certified under the Coatings for Use on Recognized Printed Wiring Boards - Component category. It performs as a 94V-0 non-flammable coating. It is intended as an easyto-use, cost-effective solution for protection against the typical risks PCB’s face in high temperature environments. It is not intended for high voltage applications (>1500 V) with extended exposures (days) to very high humidity (>95%) and temperature environments (>65 °C [149 °F]). Customers with such applications should inquire about our line of silicone conformal coatings from Momentive Performance Materials.
