MG Chemicals 422B-340G Aerosol Silicone Modified Conformal Coating

More Information


MG Chemicals 422B-55ML is a clear and clear coating that is ideal for protecting electronic circuits in high temperature environments or applications that require extreme flexibility. Protects against moisture, dirt, dust and other particles and, therefore, prevents corrosion of electronic components. It also insulates against high voltage electric arc, short circuits and static discharges. In addition, it protects against thermal shock and exerts very little pressure on the components during the temperature cycle.

Compared with other typical silicones, the 422B is a silicone acrylate on one side that makes it easier to apply, remove and rework. In addition, it has a faster curing time and a much longer lifespan.

It is available in the form of aerosol, liquid and pencil and can be applied by spraying, dipping or brushing. The 422B protective coating is UL certified under the coatings for use in recognized printed wiring boards - Component Category. It works as a non-flammable 94V-0 coating. It is thought of as a cost-effective and easy-to-use solution for protection against typical PCB risks in high temperature environments. It is not designed for high voltage applications (> 1500 V) with prolonged exposures (days) at very high humidity (> 95%) and temperature environments (> 65 ° C [149 ° F]). Customers with such applications should consult our line of conformal silicone coatings from Momentive Performance Materials.

Applications and Uses

The 422B improves reliability and extends the life of electronic circuits. Its main applications are in the automotive, marine, aerospace, aviation, communications, instrumentation and industrial control equipment industries that involve high temperatures.
