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.

Type AR Conformal Coating Examples

Posted by Sean Horn on Wed, Sep 26, 2012 @ 10:05 AM

Type AR (acrylic resin) conformal coatings are a popular choice for conformal coating projects because of their moisture protection, low cost, and ease of application.  There are many different varieties of type AR conformal coatings such as:

Will HumiSeal 1B31 mitigate tin whiskers?

Posted by Sean Horn on Tue, Sep 04, 2012 @ 01:20 PM

Tin whiskers are electrically conductive, crystalline structures of tin that sometimes grow from surfaces where tin (especially electroplated tin) is used as a final finish.  They typically grow from lengths of 1-2 millimeters (mm) but have been observed to lengths in excess of 10 mm.  They are a serious issue in the electronics world because they have been known to cause short circuits between circuit elements.

When Not to Use Acrylic Conformal Coating

Posted by Sean Horn on Wed, May 16, 2012 @ 07:52 AM

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.
