Acrylic vs Urethane Conformal Coating

Posted by Sean Horn on Tue, Apr 02, 2013 @ 08:29 AM

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.

Silicone vs. Urethane Conformal Coating

Posted by Sean Horn on Fri, Oct 12, 2012 @ 11:07 AM

Silicone and urethane are two of the most popular conformal coating types.  They are widely used for a variety of their properties, but which is a better coating?  While this ultimately depends on your application, let’s take a look at some of the pros and cons of each.

Type UR conformal coating examples

Posted by Sean Horn on Fri, Sep 07, 2012 @ 09:39 AM

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:
  • HumiSeal 1A33
  • HumiSeal 1A20
  • Humiseal 1A27
  • Humiseal 2A64
  • HumiSeal 1A34
  • Hysol PC18M
  • CONATHANE CE-1155-35
  • CONAP CE-1170
  • Techspray Fine-L-Kote
  • MG Chemicals 4223
  • Electrolube PUC

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.

Urethane conformal coating: When not to use

Posted by Sean Horn on Fri, Jul 27, 2012 @ 08:35 AM

Urethane conformal coating is becoming an increasingly popular conformal coating choice.  However, it is not suitable for all applications.  Instances where the product is going into a high vibration environment or has a high heat requirement would not ideal candidates for urethane conformal coatings.
