Three Reasons for the Growing Popularity of Parylene-Based Conformal Coatings

Conformal coatings that adhere precisely and reliably to surfaces with complicated contours and features are now used heavily in a variety of industries. From automotive manufacturers to companies that produce smartphones, interest in and reliance on conformal coatings has been rising steadily for many years.

The choice of a particular conformal coating will always influence the quality of the end result and a variety of other, associated factors. In many cases today, parylene coating makes for the best choice of all the available options.

Parylene is Well Suited to Use as a Conformal Coating in Many Situations

Every conformal coating can be characterized with reference to one or more of the materials included in it. Coatings based on the substance parylene regularly outperform others of even the most popular formulations. Some of the ways parylene-based conformal coatings tend to excel relate to features like:

  • Environmental friendliness. Many commonly used conformal coatings include volatile chemicals that can be harmful to the environment. Even where the application of a coating might not directly impact the environment, the production of the material itself might impose a fairly heavy burden. Parylene, by contrast, is an environmentally neutral substance in all the relevant respects. Businesses that are concerned about their own environmental profiles often find this to be an especially compelling reason to consider parylene-based coatings.
  • Self-initiation. Some of the conformal coatings that have been in use for the longest time include both a monomer and a substance called an initiator that reacts with that material to set the stage for polymerization. Parylene does away with the need to carefully manage and balance such processes, simplifying the application of a conformal coating in many cases.
  • Freedom from solvents and byproducts. Because parylene-based conformal coatings can be deposited, cured, and finished without the need for solvents or the production of hazardous byproducts, costs and time requirements tend to be lower.

Increasing Use of Parylene Signals a Revolution in Conformal Coatings

Since parylene provides so many benefits when used as the basis for conformal coatings, it has become steadily more popular since first becoming widely available. As a result, many experts expect parylene-based conformal coatings to become the default choice for still more applications in the future.
