Conformal Coating Application Methods
The most appropriate method of conformal coating application reflects the targeted substrate’s susceptibility to the coating material. Liquid coatings like acrylics, epoxies, silicones and urethanes possess specific performance properties. Their optimal protection and operational efficiency depends on matching these properties with the appropriate application process as well as supporting good interaction between the coating and...

Parylene: The Military-Grade Conformal Coating
Military and defense equipment are put to the test and subjected to uniquely harsh conditions on a daily basis. These mission-critical products must be rugged and able to withstand extreme temperatures and weather conditions, exposed forces of gravity that are well above and beyond normal situations and a range of contaminants such as salt, water...

What is Parylene Used For?
Composed of selected chemicals or polymer films, conformal coatings provide protective substrate coverings for all kinds of products. In addition to Parylene, acrylic, epoxy, silicone and urethane are some of the most commonly used liquid conformal coatings. They can be applied to substrates by dipping, flow-coating or spraying the coating material onto the substrate surface. Their resultant coatings typically measure between 25-75... Read More >>
How to Remove Conformal Coatings
Appropriately selected and applied, conformal coatings provide essential protection for printed circuit boards (PCBs). However, removal of conformal coatings is necessary if the wrong coating material is selected relative to the PCB’s functional requirements, inadequately supporting its operating environment. Poor coating application can trigger failure mechanisms within the assembly which also necessitate removal and re-application.... Read More >>
3 Key Properties of Acrylic Conformal Coating
Acrylic resin (AR) conformal coatings are widely used because of their distinctive beneficial properties, including protecting printed circuit boards (PCBs) and similar electronics from corrosion, dirt, dust, fungus, moisture and thermal shocks. User-friendly liquid AR can be applied by brush, dip or manual/robotic spray, generally providing a fast turnaround-time. The coating’s ease of application and... Read More >>
Does Parylene De-Wet?
Liquid conformal polymers – resins of acrylic (AR), epoxy (ER), silicone (SR) and urethane (UR) – use wet application processes to attach to substrates. Most prominent of these are brushing the wet coating onto an assembly, dipping (immersing) the assembly in a bath of liquid coating or spraying the conformal film onto the designated surface....

Silicone Conformal Coating vs Parylene
Silicone and Parylene conformal coatings may appear worlds apart initially. However, beneath the surface disparities, remarkable similarities exist. Despite their functional differences, Parylene and silicone share a crucial commonality as two of the finest options for safeguarding your company’s products. Makeup Both silicones (Type SR) and Parylenes (Type XY) are technically polymers. However, there is... Read More >>
Conformal Coating Equipment
Several coating equipment options enhance the conformal coating process. Below are the key machines crucial for liquid coatings. Spray Booth Dedicated spray booth conformal coatings are very cost-effective for medium- and higher-level production, with easy, even film application using a high-quality spray gun. Thorough ventilation is necessary to efficiently remove fumes generated by the process.... Read More >>
5 Common Misconceptions of Parylene
There are often many questions about Parylene, its properties and its ability to protect various components across industries. There are also many Parylene misconceptions. Below is a look at the five leading misconceptions. 1. Parylene does not stick to metal. This misconception is based in truth. One drawback of this coating is that its chemical... Read More >>
Masking Boots for Conformal Coating
With proper equipment and professional expertise, liquid conformal coatings and vapor-deposited Parylene readily provide printed circuit boards (PCBs) and similar electronics a durable overlay of protective, insulative film. Parylene’s chemical vapor deposition (CVD) processes ensure the coating actually penetrates the substrate surface, generating further device security. However, the very properties that help conformal coatings safeguard... Read More >>
