Properties of Acrylic Conformal Coating
Exceptionally user-friendly, liquid acrylic resin (AR) conformal coatings protect printed circuit boards (PCBs) and similar electronics from corrosion, dirt/dust, fungus, moisture and thermal shock. AR’s ease of application contributes to its status as the most frequently used conformal material. Liquid Application Methods for AR The primary means of AR liquid application are brush, dip (immersion)... Read More >>
Low Outgassing Conformal Coatings
Hermeticity and Outgassing In an ideal hermetic system that is under vacuum and completely sealed, unless gas is injected, entry of gasses from the surrounding environment is restricted. However, in reality hermetic systems can still have some leakage through their sealings and via outgassing of internal components. Outgassing is the desorption of gases/vapors from the...

Michael Osterman is associated with the Center for Advanced Life Cycle Engineering at the University of Maryland, located in College Park, MD. This article delves into the... Read More >>
Printed Circuit Boards and Parylene
While Parylene can be applied as a uniform coating across a wide variety of applications, one of its most common uses is for protecting printed circuit boards (PCBs). Product engineers utilize Parylene because it offers a unique blend of capabilities. Thin and Complete Parylene is the only commonly used conformal coating that is deposited in... Read More >>
Comparing AR to UR Conformal Coating
Acrylic (AR) and polyurethane (UR) conformal coatings are widely known as commonly utilized materials for conformal coatings. As liquid coatings, both can be applied to substrates through a variety of methods: Although both coatings are applied using similar techniques and serve some of the same product end uses, it is crucial to note that they...

Does My Product Need to Be Clean Before Conformal Coating?
Once you have decided to utilize conformal coatings to protect your device, there are two common questions that often arise: Understanding some basic knowledge about conformal coatings will help to answer these questions so you successfully find the best protection for your component. 5 Essentials for Conformal Coating Success 1. Common Contaminants: Ionic vs. Non-IonicA... Read More >>
Benefits of Automotive Conformal Coatings
Silicone and Parylene coatings are among the best options on the market to protect automotive electronics and components. Silicone coatings are applied by dipping, brushing or spraying, and Parylene coatings are applied by chemical vapor-based deposition (CVD). Advantages of each coating are listed below. Advantages of silicone coatings for automotive electronics include: Impact and shock... Read More >>
Best Conformal Coating for Moisture and Chemical Protection
Conformal coatings safeguard printed circuit boards (PCBs) from performance malfunction caused by contact with elements within their operational environment, including moisture presence within the PCB, altering its thermo-mechanical properties and chemical incursion which can quickly corrode PCB components. In addition to mitigating these specific causes of PCB malfunction, conformal coatings also provide an overlying measure... Read More >>
Safely Removing Parylene Coatings
While conformal coatings are known for reliably safeguarding the surfaces of printed circuit boards (PCBs) and associated electrical components, issues may arise that necessitate their removal. Chemical removal is suitable for wet coating substances such as acrylic, epoxy, silicon and urethane, as it causes minimal damage to PCBs. However, when it comes to Parylene, chemical...
