Conformal coatings are nothing if not trustworthy. They are placed in some of the harshest environments known to man, forced to face dangerous conditions for long periods of time without sacrificing safety, longevity, or functionality. This is possible because conformal coatings boast an impressive array of strengths that allow survival--but too often we look at the big picture and forget to appreciate the smaller benefits that work together to create this cohesive reliability. Today, we'll take a look at one of the most important strengths: corrosion resistance.

Protection from Corrosion

Technology is constantly improving--and it's improving fast. What we don't often see is conformal coatings is improving right alongside technologies in all areas. When we send our electronics into harsh environments, like the deep sea or outer space, we are exposing our tech to everything from chemicals in salt water to extreme heat or cold. We need something that is advanced enough to keep up with our high ambitions and strong enough to protect our tech even under pressure, and that's where conformal coatings like parylene come in. Designed to protect against corrosion of all kinds (including chemical, gaseous, and more), conformal coatings really do save the day.

What You Need to Know

What do you need to know about corrosion resistance and why it's so important? Let our conformal coating experts explain!

  • Science. Coatings get their amazing corrosion resistance from their low water vapor conduction properties. This means that, for example, something coated in parylene will be protected from moisture, dangerous vapors, harsh environments, extreme temperatures, and more.
  • Applications. Where are conformal coatings most valued for their corrosion resistance? Sensors, LEDs, and circuit board assemblies are just a few of the areas where coatings like parylene provide strong, long-lasting protection against corrosion.
  • Other strengths. Conformal coatings aren't limited to corrosion resistance--that's just one piece of the puzzle. Coatings like parylene also provide pinhole-free coverage, unique adaptation to crevices and hard-to-reach areas, and control over everything from clarity to thickness.
