419C Liquid Technical Data Sheet Acrylic Conformal Coating Description 419C Acrylic Conformal Coating is an IPC-CC-830B and UL 94 V-0 certified, fast drying, xylene, and toluene free product. This one-part coating provides an excellent finish, is easy to use, and does not require special or costly equipment to apply. It is ideal for high moisture environments and applications requiring easy repair and rework. 419C coating protects electronic circuit against moisture, dirt, dust, and thermal shocks that could corrode, short circuit, or damage the electric component. It insulates against high-voltage arcing, shorts, and static discharges. As well, this coating provides a high dielectric withstand voltage that allows traces to be put closer together which helps with miniaturization.
