Conformal and Protective Coatings


Printed circuit boards may experience degraded accuracy or even fail if insulating surfaces become contaminated. However, a circuit board conformal coating can protect electronic circuitry from moisture, dust, corrosion, chemical environments and thermal shock that if uncoated could potentially lead to catastrophic failure. We carry silicone, acrylic and urethane printed circuit board coatings in order to accommodate various applications. We also offer a non-drip conformal coating stripper that will effectively remove protective coatings, adhesives, tar and carbon. If you’re looking for an aerosol solution, we stock a conformal coating spray that provides a tough clear finish and protects against static discharge.

Acrylic Conformal Coating is a durable finish product that provides an all round protective coating for printed circuit boards against moisture, corrosion, and thermal shock. It protects and insulates electrical and electronic components and assemblies, including generators, motors, transformers, relays, and solenoid coils. For spraying, liquid can be thinned using M.G. Thinner Cleaner. Thin up to one half part thinner to one part coating. Also available in a micro tip pen format.
Our 419C Acrylic Conformal Coating is an IPC 830 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 equipment to apply. It is ideal for high moisture environments and applications requiring easy repair and rework.

The 419C coating protects electric circuit against moisture, dirt, dust, thermal shocks, and scratches that could corrode, short circuit, or otherwise damage the electric component. It insulates against high-voltage arcing, shorts, and static discharges. As well as, this coating provides a high dielectric withstand voltage that allows traces to be put closer together helping with miniaturization.
