Conformal coatings are thin protective layers applied to circuit boards to safeguard them from environmental threats. These coatings conform to the board’s shape and shield components from moisture, corrosion, chemicals, and temperature extremes. With various conformal coating options available, the right choice for your project depends on factors like the specific environmental stresses the board will encounter and the desired properties of the coating itself.  

The provided chart below can be a helpful tool in navigating these options and selecting the most suitable conformal coating for your project’s needs.
