Conformal coating is a protective non-conductive dielectric layer that is applied onto the printed circuit board assembly to protect the electronic assembly from damage due to contamination, salt spray, moisture, fungus, dust, and corrosion caused by harsh or extreme environments.
It is most commonly applied to products that are used in outdoor environments where heat and moisture are prevalent. Coating may also prevent damage from rough handling, installation, reduction of mechanical and thermal stress. It also acts to protect circuitry and components from abrasion and solvents.
Commonly used conformal coatings are silicone, urethane, and acrylic. The chemical and physical property of the materials is different, so is the degree of protection. The basic characteristics of the materials are described below.
Comtrol offers three different types of Conformal Coatings, but only 1 type of material for each of these coatings (shown below), if a coating is required that Comtrol doesn’t offer please contact your sales rep to see if it can be provided to fulfill the requirement.
