When Not to Use Acrylic Conformal Coating
While acrylic conformal coating does have many benefits, it is not the best solution if an application will be exposed to solvents, needs to withstand high temperatures or requires coating hardness. Solvent exposure Acrylic conformal coating can be removed with a weaker solvent such as isopropyl alcohol or xylene. If the coating encounters even stronger solvents,... Read More >>
Type UR Conformal Coating Examples
Type UR (urethane resin) conformal coatings are a common choice for conformal coating projects because of their resistance to chemical solvents, hardness and moisture protection. Common type UR conformal coatings include: UR conformal coating offers exceptional resistance to chemical solvents, making it ideal for applications exposed to harsh chemicals. Additionally, consider urethane conformal coating for... Read More >>
How to Source Conformal Coating Removal Services
Conformal coatings protect PCBs and ensure they work reliably throughout their expected operational life. However, poor coating application or selection of the wrong coating material can cause assembly malfunction. In other cases, poorly manufactured PCBs may need component repair/replacement. When these problems arise, coating removal is necessary. Removal Methods Removal depends largely on the coating... Read More >>
Sterlization of Parylene
Regardless of the variant, Parylene, is highly acclaimed for the many advantages it offers as a protective conformal coating for medical, aerospace, defense, LEDs, and automotive applications. Chief among the coating’s benefits, however, is that it can withstand common sterilization techniques, such as electron beam (e-beam), gamma, ethylene oxide (EtO), and steam autoclave. Like many...

Benefits of Conformal Coatings
Manufacturers in the electronics, transportation, aerospace, defense and medical industries have applications that need to withstand elements of heat, cold, rain, snow, vibration, fungus, oxidation and corrosion through decades of operation. Without protection, their applications would not survive these harsh environments. Conformal Coatings Protect Circuit Boards and Electronic Devices from Their Environments Conformal coatings add a...

Parylene Process: 5 Keys to Success
Parylene Process: The basic Parylene variant is Parylene N (poly-para-xylylene). Additional variants of Parylene can be achieved via chemical modification to Parylene N main-chain phenyl ring and its aliphatic carbon bonds. Parylene N’s modification by a functional group such as Chlorine and Fluorine leads to Parylene C (poly (2-chloro-para-xylylene)) and Parylene F, respectively. Derivatization results... Read More >>
Top 5 Myths of Parylene
Although Parylene (XY) is a well-recognized and regularly used conformal coating, misconceptions about what it is and can do are common. These mistaken beliefs interfere with true understanding of Parylene’s uses. Five of the most common misconceptions – and appropriate corrective information – should clear things up. 1. Parylene Is Too Expensive for Normal Use.... Read More >>
Conformal Coating Selection: Weighing the Pros and Cons for Your Application
Utilized in medical device, electronics, defense, aerospace and transportation applications, conformal coatings are applied to a product to provide protection from hazardous substances and harsh environments. Optimal protection, however, is contingent upon proper selection of the conformal coating type. This critical task requires engineers to carefully weigh the benefits and drawbacks of the five main...

Parylene vs. Potting
If you have a component that needs protection, you typically have a choice between potting and conformal coating. While potting offers the largest and most powerful barrier against external harm, it also carries some significant drawbacks. Conformal coating, especially with Parylene, also offers a protective barrier, but does it without the challenges that potting poses.... Read More >>
5 Key Properties of Parylene
Since its discovery in the 1940s, Parylene has established a strong presence as the ideal conformal coating for a variety of applications. Given its unique blend of properties, it presents itself as an unparalleled conformal coating option, depending on the application being coated. There are several distinct properties of Parylene, including electrical properties, broad temperature... Read More >>
