Here we look at the market's five main conformal coating types: Acrylic, Silicone, Polyurethane, Epoxy, and Parylene-based. Conformal Coating TypesĮvery kind of coating has unique properties and characteristics suitable for specific applications. This article aims to explain precisely how conformal coating will benefit you and which type is the best option for your specific application. There are several types of conformal coating, and each has unique characteristics, properties, and benefits. This protection consequently improves the reliability of your device, reducing costs associated with replacing hardware that has prematurely failed. The key benefit of applying a conformal coating is that the protection will extend your circuit board's life and reduce component failure rates due to environmental factors. Conformal coatings also have thermal and electrical insulation properties to help manage your circuit's operating characteristics. It protects circuit boards and components against various environmental factors, including heat, humidity, moisture, ultraviolet light, chemical contaminants, and abrasive materials.

Conformal coating is a lightweight material applied to PCBs that acts as a protective layer.
