Comparing AR to UR Conformal Coating

Posted by Sean Horn on Fri, May 27, 2016 @ 07:30 AM

Acrylic (AR) and polyurethane (UR) conformal coatings are among the best known and most commonly used conformal coating materials.  As liquid coatings, both can be applied to substrates through a variety of methods:

How Parylene is Applied Compared to Other Conformal Coatings

Posted by Sean Horn on Fri, Aug 21, 2015 @ 01:45 PM

Overall the generic name parylene describes a distinct collection of polycrystalline and linear organic coating materials with innumerable applications.  The essential basis of today's parylene N, p-xylene, was inadvertently synthesized at England's University of Manchester in 1947The filmy residue resulted after high-temperature heating of compounds of toulene and the xylenes polymerized into para-xylene.  The substance immediately demonstrated an exceptional capacity for generating the fine but resilient surface-covering that characterizes today's range of parylene conformal coatings.

Differences between Parylene and Acrylic Conformal Coating

Posted by Sean Horn on Fri, Apr 17, 2015 @ 09:00 AM

Parylene and acrylic conformal coatings represent two extremes of the types of compounds you can use to coat printed circuit boards, sensors, or other devices. While acrylic is popular and inexpensive, parylene offers some of the best performance of any coating compound.

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.

Parylene vs Acrylic Conformal Coatings

Posted by Sean Horn on Wed, Feb 13, 2013 @ 02:34 PM

Parylene and acrylic resins are both conformal coatings.  Most of the similarities stop there.  Because their properties vary so much, they have their own unique uses and capabilities.

Parylene Alternatives

Posted by Sean Horn on Fri, Jan 18, 2013 @ 08:43 AM

Parylene conformal coating is a very robust coating, but sometimes it is not the right fit for a customer’s application for one reason or another.  The entire conformal coating process is based on first identifying the standards to be used and customer’s protection desired.  It would therefore only make sense that there are alternatives to parylene for different conformal coating demands.

What is a good thickness for acrylic conformal coating?

Posted by Sean Horn on Mon, Jan 07, 2013 @ 10:57 AM

Acrylic conformal coatings, such as MG Chemicals 419C and Humiseal 1B31 are a very popular conformal coating choice.  They are used primarily for moisture protection on printed circuit boards.  Often times, they are the cheapest conformal coating to apply because of their easy to use nature.  As a result of this, people try to apply acrylic conformal coating as a DIY project.  An issue that arises frequently is an improper thickness of coating, resulting in lackluster protection.
