  1. The Pros and Cons of Metal Protection Coatings

  2. Parylenecomes underneath the category of polymer coatings that serve as dielectric and moisture-resistant components. The polymer coatings display a linear or polycrystalline structure. The polymer's chemical structure ensures the coatings are exceptionally uniform and thin. Parylene coatings can be combined with the substrate at the molecular stage, which entails this coating will appear uniform and even throughout the complete substrate. Besides, parylene is applied on stents and electrical components like heart pumps exposed to bad weather conditions, such as those in the aerospace and automotive industries. Parylene is a perfect coating for the protection of different components used in the instrumentation, medical, and electronics industries. The advantages offered by Parylene are listed below: • Biologically and chemically inert: This can allow you to implant the parylene coated components with little risk of infection or rejection.

  3. Transparency:Parylene coating is perfect for optical components due to its complete transparency. • Stress-free: This coating is free from internal or surface stresses as the coating is carried out at room temperature. • Excellent surface protection:Parylene has exceptional properties like thermal, moisture, chemical, and environmental resistance. • Conformal: The gaseous property of the deposition procedure allows parylene coatings to cover surfaces completely. It can coat surfaces including deep crevices, difficult-to-reach regions, and sharp points evenly. Parylene is pinhole-free and doesn't pull away from edges or corners. • Room temperature application:Parylene is suitable for use on various materials, especially delicate substrates. Besides, it can become effective even without adding mass or weight.

  4. Green technology:Parylene is completely safe for the surroundings when compared to liquid coatings. Often, liquid coatings consist of high VOCs. • Optical clarity: The clear visibility and transparency of parylene film impart visibility to surface features along with printing, which is helpful in quality assurance tests. • Parylene offers excellent protection against like conformal coatings. Besides, it brings features like excellent gas protection, moisture protection, along with high dielectric strength and bio-compatibility, to the table. However, there are several disadvantages of using parylene coatings. To start with, parylene is costly in comparison to conformal coatings. This is mainly due to the process involved and the inclusion of raw materials. in most cases, extensive labor is needed to prepare a tool for coating. The application of parylene is usually a batch process. As a result, there's only limited space available within the chamber for each coating machine operation. Here, the objective is to include several items within the chamber that requires coating.

  5. The parylenedimer and raw materials are costly. As parylene is applied via the vapor deposition procedure, all items like the chamber's inner diameter are coated. Thus, this makes the parylene coating process wasteful and inefficient while escalating the final cost. Preparing an article or masking it for parylene covering is a labor-intensive matter. As parylene is usually applied in the form of a vapor, it reaches out to every nook and corner. Eventually, parylene displays poor adhesion to several metals. For example, parylene can't adhere to silver, gold, stainless steel, and similar metals. You can learn more about metal protection coatings.
