Parylene Alternatives
Depending on a customer’s application needs, a liquid conformal coating might offer the best alternative to Parylene. The first step in determining which conformal coating to use involves identifying the standards to be used and the customer’s desired protection goals. Some of these alternatives—as well as their overall advantages—include the following: A global network of... Read More >>
Which Conformal Coating Is Right for Me?
The effectiveness of polymeric conformal coatings in protecting printed circuit boards (PCBs) from damage due to environmental factors, such as dust, corrosion, moisture and temperature fluctuations, has been well-documented. While conforming to the physical configurations of the exposed face of the PCB, the conformal coating also: While conformal coatings are the optimal choice for preserving... Read More >>
What is Parylene Conformal Coating?
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 most commonly used for conformal coating today. They can be simply applied to substrates – by dipping, flow-coating or spraying the coating material onto the substrate surface. Their resultant coatings typically measure between 25-75...

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 >>
