How Much Does Parylene Coating Cost? - All Things Considered

Parylene chemical formula on a dollar bill

 

Parylene coatings are known for robust protection from liquids, corrosion, chemicals, and strong electrical activity at a fraction of the thickness of alternative coatings, such as acrylics, epoxies, silicones, and urethanes. Additionally, Parylene is biocompatible, with beneficial optical properties, and delivers superior protection at 50% thickness of conventional coatings, such as acrylic conformal coating or epoxy. However, the perceived cost of Parylene dimer and Parylene labor costs, compared to other conformal coatings, can give design teams hesitation as they consider incorporating high-reliability protection into their project.

Is Cost-Efficient Parylene Possible?

 

Despite its proven performance, many perceive Parylene coating as challenging and expensive to apply. Therefore, one assumption is that it is only appropriate in extreme mission-critical situations, such as military, medical, or aviation applications. Other common misconceptions about Parylene include the following:

  • Reworking and removing Parylene is impossible
  • Parylene coating equipment is too expensive and complicated to use
  • Masking is too complex and time-consuming to bother with
  • CVD coatings (chemical vapor deposition) entail long batch times leading to higher labor costs and low throughput

Although these assumptions are unfounded, it is a fact that Parylene coating is typically the most costly of all conformal coating options. As a result, it's important to choose a partner who can work within your budget constraints and assist you in estimating potential expenses.

 

How to Calculate the Cost of Parylene

 

HZO capital equipment being used to lower Parylene coating cost

 

At HZO, we have crafted processes and procedures to lower the costs of the Parylene coating processes. However, three factors are pertinent to the price regardless of whom you work with.

 

Parylene Type

 

Common varieties, such as Parylene C and Parylene N, are less costly in raw coating material known as Parylene dimer. “Specialty types” such as Parylene-AF4 will cost more but will enable better performance in terms of UV and heat resistance. A consultation with a Parylene conformal coating services provider, such as HZO, will help you determine which Parylene type is most suitable for your project.

 

Masking

 

Masking can be more complex with Parylene coatings, resulting in increased labor. However, altering the design of your product can make it easier to coat and mask, reducing associated costs. HZO has industry-leading automated and semi-automated masking and demasking equipment, simplifying the process and reducing expenses should you choose to work with us.

 

Quantity and Size of Objects that Require Coating

 

With Parylene, the objects you need to coat are placed into a vacuum chamber as part of the chemical vapor deposition (CVD) coating process, and each coating run will have a fixed cost. However, you can optimize the number of components coated in each run to lower the coating cost per item. Meanwhile, we have built proprietary coating equipment that can house more items at once per coating run than any other Parylene company in the industry, minimizing costs per coating run.

 

Other Critical Considerations When Evaluating Parylene’s Price

 

Aside from considering upfront costs, to accurately assess Parylene’s coating expense, you must consider the coating’s value in terms of performance to preserve product function over time. In other words, the total cost of ownership is a critical consideration – upfront coating expense cannot fully measure value over a product’s life cycle. Parylene’s superior conformality and protection capabilities dramatically reduce field failures, warranty costs, and downtimes.

When you take the long-term view, the productivity and warranty savings that Parylene provides over time can make it the most economical coating option. There are other savings to consider when evaluating the price of conformal coatings, such as manufacturing costs. Conventional coatings entail cure cycles, VOC emissions, toxic byproducts, flammability, waste disposal, and health concerns. Parylene does not raise these safety and sustainability concerns as an environmentally friendly process.

Finally, investing in Parylene, with its exceptional dielectric strength, chemical and moisture resistance, and stress-free encapsulation, can substantially reduce the TCO to ruggedize components compared to other options.
