Type AR Conformal Coating Examples
Type AR (acrylic resin) conformal coatings are a common choice for conformal coating projects because of their moisture protection, low cost and ease of application. Common type AR conformal coatings include: SCS is the world leader in conformal coatings, including type AR coatings. To discuss using acrylic conformal coating for your application, call +1-317-244-1200 or Contact SCS online.... Read More >>
Where to Buy Parylene
Materially, Parylene is the most distinctive of the major conformal coatings. But just how does it differ from liquid coatings — acrylic, epoxy, silicone and urethane? Liquid coatings are just that, wet; they begin as liquid and are applied to substrates in that format, by brushing, dipping or spraying the fluid material onto the substrate.... Read More >>
Parylene Coating Nitinol
A metal alloy of nickel (Ni) and titanium (Ti), nitinol (NiTi) exhibits the properties of shape memory and super-elasticity, which make it very useful for utilization of conformal coatings. Nitinol devices are typically of high value and are often difficult and expensive to produce; the extreme reactivity of the alloy’s titanium component requires exceptionally tight... Read More >>
Choosing Parylene Thickness
One common question from those who are new to conformal coating is how to choose the right Parylene thickness. One factor to take into consideration when determining the right Parylene thickness is the amount of clearance needed. For example, if the printed circuit board that needs coated has an enclosure, there usually will not be too... Read More >>
NASA Inspection Criteria for Conformal Coating
The Workmanship Standards developed by the National Aeronautics and Space Agency (NASA) are essential to assuring reliable performance of the aeronautic, defense and space equipment it uses and monitors. Conformal coatings have many applications for these purposes, particularly to provide protection for printed circuit assemblies (PCAs) commonly found in computers or specialized electronic equipment which...

Why Conformal Coat
Printed circuit boards are extremely susceptible to a wide range of contaminants that can cause a significant amount of damage in a relatively short period of time. These contaminants include moisture, dust and harmful chemicals. In addition, electronic circuits are also susceptible to extreme temperatures and environments. Conformal coatings provide a protective coating that can... Read More >>
Parylene Coating: Outsourcing vs. In-House
Parylene coating provides critical protection to many electronics, medical devices and defense components. Applying Parylene to components and devices can be done in-house or by a dedicated third party. Knowing which one is right for your operation is key to ensuring an effective, affordable and reliable end product. Below is a look at the differences... Read More >>
Reapplying Conformal Coating after its Removal
Defects to either the PCB assembly or its conformal coating can be sufficient cause for coating removal. Whether repair technologies address the circuit board’s components or the conformal film, subsequent post-repair coating (recoating) processes need to address: Old Coating Removal The complexity of stripping damaged or otherwise unwanted conformal coating from a circuit board is...

The Benefits of Acrylic Conformal Coating
Acrylic conformal coatings are a commonly used conformal coatings. Acrylics’ main benefits include its physical properties, convenient cure time and low cost. Acrylic conformal coatings are extremely user friendly, allowing for the ease of application either by brush, dip or spray. Additionally, acrylics typically offer the fastest cure time in comparison to other liquid coatings.... Read More >>
Solvent Resistance of Parylene
Parylene variants offer robust solvent resistance, protecting substrates like printed circuit boards (PCBs) and other electronics components. This high level of protection is sustained over a wide temperature range that exceeds typical operating conditions for PCBs. The exceptional solvent resistance of Parylene is attributed to its unique molecular structure, which makes it largely insoluble in... Read More >>
