422B is a 1-part, acrylic-silicone blend conformal coating that cures to a durable, flexible and smooth finish. It is easy to apply and can be handled in only 8 minutes. It may be removed with appropriate strippers, or soldered through for repair or rework. prized principally for their high temperature resistance and softness. Compared to most other conformal coating types, silicones have an exceptionally low modulus, which makes them ideal for coating delicate surface mount devices or for applications that involve harsh thermal cycling.
