Conformal Coatings Guide and Overview
This article is based on an original publication by Chemtronics.
Engineered to protect circuit boards and other electronic components from adverse environmental conditions, conformal coatings adhere to irregular surfaces to ensure dielectric resistance and operation integrity.
Conformal Coating Resin Types
There are five main categories of conformal coatings:
- AR - Acrylic Resin
- SR - Silicone Resin
- UR - Polyurethane (Urethane) Resin
- ER - Epoxy Resin
- XY - Parylene
