There are vast and various benefits of using conformal coating for almost any everyday product. Truly, it's a science.

So one could safely make the assumption that once the type of conformal coating is done, you're good to go.

Not the case.

Choosing the right conformal coating is just the first step, now you have to apply it, and apply it correctly. It's crucial to understand the application process so that it can be carried out properly and efficiently. Without being applied correctly, conformal coating won't be able to offer any of the benefits we rely on in almost every industry.

Appreciating the Application

The decision to use a conformal coating is only the first step in many overlapping processes that result in the longevity, reliability, and overall safety that we have come to expect from coatings like parylene. However, while a lot of focus is being put on selecting the perfect type of coating and ensuring that the finished product is functional, it often becomes easy to overlook one of the most important steps: application. The application process is crucial because it determines not only the success of the coating at providing protection, but also the longevity and functionality of the finished product itself. This is why it's crucial to understand and appreciate the application process.

A Closer Look

What is involved in the application of conformal coating? Which necessary steps are most often overlooked? Let our conformal coating experts explain!

  • Cleaning. One of the biggest enemies to a successful and long-lasting coating is preexisting contamination. If the material itself is unclean before application, the coating won't bond properly and won't be able to provide a high level of protection. This is why cleaning is often one of the most important parts of the application process.
  • Thickness. It is evident from the onset of any project that coating thickness must be precise to be efficient. As it turns out, the application process has a significant influence on the thickness and the overall coverage of a conformal coating. Different techniques result in different levels of precision, which means that this is one step that can't be overlooked.
  • Details. When it comes to the application process, otherwise-small details become crucial. For example, the temperature during application can impact the consistency of the coating, while humidity and ventilation affect the coating's success and longevity.
