How to Choose a Conformal Coating Company
coating, you may be looking at several options and wondering how to choose a conformal coating provider. This decision requires a great deal of consideration because it can have a significant impact on the product’s quality and your company’s profits and reputation. But what exactly should you be looking for when choosing a conformal coating... Read More >>
Parylene Coating Measurement Methods
Used as moisture and dielectric barriers, Parylene (p-xylylene/XY) coatings are conformal and pinhole free. Applied by a unique vapor deposition polymerization (VDP) method, Parylene penetrates beneath substrate facades, simultaneously attaching above surfaces at the molecular level. VDP generated films cover crevices, exposed internal regions, points and sharp edges uniformly, without gaps or breaches. Compared to... Read More >>
The Parylene Deposition Process
Parylene coating is applied onto a substrate or material through a vapor deposition process. Depending on the Parylene variant and required thickness, Parylene typically deposits at a rate of about 0.2/mils per hour. A Parylene machine run can vary from as little as 1 hour to over 24 hours. The process begins with raw dimer... Read More >>
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 >>
