HZO specializes in high-reliability Parylene coatings, providing advanced protection for electronic components in industries where performance and durability are critical.
With a commitment to quality and innovation, the company refines its proprietary coating processes at its headquarters in Morrisville, North Carolina, while offering global coating solutions tailored to diverse industry needs.
Flexible Coating Integration Options
HZO enables customers to integrate the Parylene coating process in two ways: through a factory-in-factory model within their own facilities or by utilizing an HZO Center of Excellence at a convenient global location. The process begins when customer-provided components arrive at HZO’s facility, where they undergo a rigorous inspection to ensure they meet the necessary quality standards before coating.
A Controlled & Precise Coating Application
Each component is meticulously prepared through a masking process that protects designated areas from being coated. Various masking materials—including tape, caps, and specialized adhesives—are applied based on specific engineering requirements. Once masked, the components are placed on trays and loaded into HZO’s proprietary coating chambers for the batch coating process.
The Parylene coating process itself involves the conversion of solid Parylene into a gas, which is then introduced into the chamber under controlled conditions. Unlike other conformal coating methods, this vapor deposition process occurs at near-room temperature, allowing for a uniform, microns-thin protective layer to form on all exposed surfaces of the components.
Post-Coating Inspection & Quality Assurance
After the coating process is complete, the components move to the demasking stage, where the protective masking materials are carefully removed. Specialized tools and techniques ensure that the coatings remain intact while preserving the integrity of the original design. A final quality inspection verifies that the coatings meet HZO’s rigorous standards before the components are packaged and shipped back to the customer for further manufacturing or assembly.
Engineering Excellence & Reliability
By designing and building its own coating equipment, HZO ensures high throughput, repeatability, and precision in every batch. With a focus on efficiency, quality, and customer satisfaction, the company continues to advance Parylene coating technology, delivering superior protection for critical electronic components across a wide range of industries.
