422B-340G

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. It is not intended for high voltage applications (>1500V) with extended exposures (days) to very high humidity (>95%) and temperature environments (>65°C [149°F]).
