Acrylic and urethane conformal coating are widely used conformal coatings. While they share the same methods of applications and ultimate end item uses, there are some differences that should be addressed prior to deciding what conformal coating is the best for your project.

We have noticed a significant increase in the amount of type SR conformal coating requests recently. Silicone conformal coating offers many benefits such as high temperature capabilities, excellent moisture protection, and easy application and re-workability.

Type UR (urethane resin) conformal coatings are a popular choice for conformal coating projects because of their resistance to chemical solvents, hardness, and moisture protection. There are many different varieties of type UR conformal coatings such as:

You should consider using type ur conformal coating whenever your application has any issues with chemical resistivity as type ur coatings are very resistant to chemical solvents. Type ur conformal coating is also smart to include in any tin whisker mitigation strategy, as NASA studies have shown that urethane conformal coatings are one of the few ways to successfully mitigate tin whisker growth. Finally, applications that can see any direct mechanical wear against the coating should consider urethane conformal coatings as well.

While acrylic conformal coating does have its many benefits, there are some applications whenever it is not the ideal conformal coating to be using. Typically in applications that have exposure to solvents, high temperature requirements, or require coating hardness, acrylic conformal coating should not be used.

Solvent exposure
In applications that have an exposure to solvents, acrylic conformal coating is not the best choice. Acrylic conformal coating can be removed with a weaker solvent such as isopropyl alcohol or xylene. Whenever it faces even stronger solvents, it will not offer the protection that is needed, especially if your product is a mission critical device. Other coatings, such as urethane or parylene conformal coating have a far better resistance to solvents than acrylics.
