Parylene Thin-Film Coatings

Parylene Conformal Coating Services for Electronics

If your business plans to produce a product that needs to withstand the most demanding environments, traditional electronic protection methods will not deliver. While encapsulation and seals are initially good options, these materials do not stand the test of time, wearing away and becoming brittle. Parylene coating services provide an ideal alternative solution to answer your protection needs.

Parylene is an ultra-thin, lightweight material that provides sturdy, proven protection for electronics across the spectrum, from home and lifestyle to industry and global enterprise. This powerful material outperforms traditional conformal coatings, offering the highest standard of protection at the thinnest amount of coating thickness.

Across industries and applications – automotive, aerospace, medical devices, and home appliances – OEMs choose Parylene coating services to make more reliable products with long-lasting corrosion protection and contaminant protection.



Parylene protection from HZO yields products that are:

Bulk Free

Efficiently thin microns of Parylene, instead of millimeters or more of conventional coatings.

Pinhole Free

Consistently and conformally  coated – free of pinholes, cracks, or voids.

Worry Free

Proactively protected devices reduce product returns and recalls.

What Are Parylene Coatings?

Parylene conformal coatings are a thin-film protection material produced by chemical vapor deposition (CVD). This process deposits a uniform film on the packaged component that is part of the PCBA.

Deeply penetrating the tiniest of crevices across some of the most complex printed circuit board assembly topography, Parylene is a strong barrier at the microlevel.

What Are The Benefits of Parylene?

Ultra-Thin and Lightweight Coating

Shed excess weight at micron-level thinness and reduce the bulk of your finished products with slim coating thickness

Uniform Coating Thickness
Rest easy with a highly repeatable process that results in minimal variation.
Tin Whisker Mitigation
Prevent product recalls by using Parylene to mitigate damage caused by tin whiskers.
Transparent Layer

Enhance your product’s aesthetics with a visibly clear protective film and barrier layer.

Thermal Stability

Benefit from a material that is inert, it’s thermal properties allow it to withstand conditions below freezing.

Superior Chemical Resistance

Parylene is more chemically resistant than all but the most engineered silicones in resistance to chemical attack.

HZO’s Parylene C is Recognized by UL

Representative samples of this component have been evaluated by UL and meet applicable UL requirements.

Parylene Coatings for Electronics –
The HZO Advantage

Think of all the unpredictable environmental threats possible that could affect the functionality of your products. The properties of parylene create the ideal coating solution and will ensure that your products function reliably in the wake of uncertainty.

As a leading Parylene coating solutions provider and parylene coating company, we take a unique approach to the coating process, designing and building proprietary equipment in-house with the industry’s largest coating chambers. This equipment’s large chambers is cube-shaped, allowing for more devices to be coated at once, enhancing reliability, optimizing throughput, and increasing yield.

Why Use Parylene Coatings?

From a smartphone that falls into a swimming pool to a video camera held in a downhill skateboarder’s sweaty palm, everyday electronics require durability for common accidents and extreme circumstances. Parylene technology allows your products to function as devices should, predictably, and dependably.
