Removing Conformal Coating Instead of Repairing It
Sometimes problems with conformal coating are too complicated or difficult to repair. This can occur when bubbles develop in the coating during the application process. Bubbles cause voids in the coating that defeat its protective, insulating purpose, suggesting the need for removal. Other situations that lead to inadequate coverage, and may favor coating removal rather... Read More >>
Parylene Conformal Coatings for Oil & Gas Sensors
Parylene, a transparent polymer, provides seamless and void-free conformal coatings. Variants like Parylene N, C, D and Parylene HT® are crafted through molecular structure tweaks, each yielding distinct material properties for various applications. Among these derivatives, the fundamental type is Parylene N, derived from the poly-para-xylylene monomer. Parylene presents numerous benefits for application in the... Read More >>
What Is the Proper Adhesion Test for Conformal Coating?
Essential steps in researching conformal coatings include confirmed testing of coating properties as well as adhesion. An online search for “conformal coating adhesion test” results in a number of documented tests and standards. These include tests from the International Standards Board (ISO) and the American Society for Testing and Materials (ASTM). One must exercise caution,... Read More >>

Product and process conformity assessment is the key to Nadcap’s industry-managed accreditation criteria, generating... Read More >>
How Parylene Protects Electronics in Harsh and Hostile Environments
Parylene comes from a series of polymers from paraxylene and is often used as a coating that safeguards electronic devices. Specifically, Parylene coating is a conformal coating applied at room temperature using a chemical vapor deposition (CVD) process. For many industries, Parylene shields electronics from contamination, corrosion and complications arising from exposure to harsh and hostile environments. Parylene Coatings... Read More >>
What Is Type XY Conformal Coating?
Type XY conformal coating, also known as Parylene, derives its name from its full chemical name, para-xylylene. To streamline its classification with other conformal coatings like acrylics (AR), silicones (SR), epoxies (ER), and urethanes (UR), the shorter name “Parylene” was eventually adopted. Type XY Conformal Coating Application Type XY conformal coating is applied through a... Read More >>
Conformal Coatings for LED Applications
Conformal coatings elevate the performance of LEDs. Whether it’s enhancing color accuracy, providing protection against damage, or ensuring optimal electronic performance, conformal coating extends the applicability of LED technology. Discover the top six ways in which conformal coating and LEDs complement each other seamlessly. 1. UV Resistance Many types of LEDs are sensitive to the... Read More >>
Elongation Properties of Parylene
For conformal coatings, elongation is a measure of material ductility — a specific coating’s ability to undergo significant plastic deformation before rupture. A coating’s yield elongation is the maximum stress the material will sustain before fracture. Thus, computed Parylene elongation measurements represent the total quantity of strain the conformal film can withstand before failure. While... Read More >>
Comparing Lubricious Coatings
Selection of conformal coatings for medical devices takes into account a host of considerations including the operational environment it will encounter when employed. Additional operational/performance factors can also include the chemical, electrical and mechanical compatibility between the coating and the device, and the temperature variation the device is expected to encounter. Equally important in many... Read More >>
Parylene for Military Sensors
Security systems rely on different types of advanced, intelligent and connected sensor technologies. Application areas are diverse, including radar systems, vision, night vision (IR-cameras), acceleration/ orientation/location detection (accelerometers, gyroscopes, GPS), chemicals (neural toxins, other toxic gases, liquids), wearable sensors (temperature, humidity, location detection), barometric (under water), air flow (aerospace, munitions), and they are brought together...
