What is Acrylic Conformal Coating?
Acrylic conformal coatings are easy-to-use, 1-part coatings that cure by physical drying. These coatings impart excellent dielectric properties and protect against moisture, dust and fungus.
Advantages of Acrylic Conformal Coating
Acrylic conformal coatings provide circuits with excellent protection against moisture, dust and fungus. Their main advantages over other conformal coating chemistries are their cost, ease-of-use, and ability to be reworked.
Disadvantages of Acrylic Conformal Coating
The biggest shortcoming of acrylic conformal coatings is their lack of chemical resistance. While they are great in relatively mild environments to protect against moisture, dust and fungus, they lack the crosslink density to hold up to more aggressive chemicals like fuel vapors. To ensure that you have the right conformal coating solution, it is important that you know all of your application’s requirements.
