Typical Applications

Protective coatings like this RS PRO conformal coating, is a thin polymeric film applied to a printed circuit board (PCB) in order to protect the board and its components from the environment and to prevent corrosion. The protective coating is designed to cover and protect solder joints, the leads of electronic components, exposed traces, and other metallised areas from corrosion, ultimately extending the working life of the PCB. Conformal coatings are used in many different types of applications where high performance and reliability are needed including.
Automotive
Military
Aerospace
Marine
Lighting
Industrial
Mobile electronics

FAQs

Why do I need a Conformal Coating?
Printed circuit board performance can be affected due to moisture, chemicals, salt stray and temperature extremes. A protective coating can be used in order to protect printed circuit boards and their components and ultimately prevent corrosion and failure.

Types of Conformal Coatings

• Silicone coatings give great protection in a wide range of temperatures, have good chemical resistance, flexibility and are resistant to sea salt.


• Acrylic coatings are easy to use and remove, provide fair elasticity, are abrasion resistant and have a high dielectric strength.


• Polyurethane coatings have excellent moisture and chemical resistance properties and are abrasion resistant.


• Epoxy coatings give good humidity resistance, high abrasion and chemical resistance
