Acrylic Conformal Coating 419C Technical Data Sheet 419C-Liquid Description Our 419C Acrylic Conformal Coating is an IPC-CC-830B and UL 94-V0 certified, fast drying, xylene and toluene free product that provides an excellent finish. This one part coating is easy to use and does not require special or costly equipments to apply. It is ideal for high moisture environments and applications requiring easy repair and rework. The 419C coating protects electric circuits against moisture, dirt, dust, and thermal shocks that could corrode, short circuit, or otherwise damage the electric components. 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 helping with miniaturization. Applications & Usages The 419C coating improves reliability, operational range, and lengthens the life of electrical and electronic components and assemblies. Its primary applications are in the automobile, marine, aerospace, aviation, communication, instrumentation, industrial control equipment, and consumer electronics industries. Common acrylic conformal coatings uses are with electric generators, motors, transformers, relays, and air bag controllers. The 419C coating can serve to protect high technology devices like cell phones, computer tablets, avionics, and more.
