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... Read More >>
How to Estimate Parylene Coating Costs
Often considered the ultimate conformal coating, Parylene is well suited to protect many types of products and devices. Each customer application requires its own detailed and precise process, which means estimating the potential cost of a Parylene coating project is essential. 3 Questions to Help You Estimate Cost 1. “What type of Parylene am I...

Parylenes for Biomedical Implantable Devices
Whenever implantable medical devices come into contact with the human body, long-term protection against body fluids, enzymes, proteins, lipids and more is vital. Biomedical surfaces commonly require a layer of protection in order to not degrade in the presence of moisture, chemicals and other potentially harmful substances. A downfall for wet chemistries, e.g., liquid coatings... Read More >>
Parylene Adhesion to Noble Metals
Parylene adhesion can be difficult to manage. Unlike other coatings that adhere to the surfaces they coat, Parylene sticks to itself. This can cause issues when it needs to be applied to smooth surfaces, like areas made of stainless steel or noble metals like gold or silver. Given Parylene’s numerous advantages, investigating methods to enhance... Read More >>
