Inadequate coverage is a shortcoming of some surface treatments that may pose a problem for certain applications. "Our product, parylene, is never a liquid, so it doesn't have the low-coverage drawback associated with liquid coatings," says Andrew Brooks, electronics market manager for Specialty Coating Systems (Indianapolis, IN, USA). "Parylene is a gas-deposited polymer, and because of this, it is conformal and has uniform thickness. It doesn't have any voids, pinholes, or low-coverage areas," Brooks adds.
The material's benefits include barrier properties and reliability. The barrier qualities help prevent penetration from moisture, chemicals, gasses, and biofluids. The thin, transparent polymer film seals the surface microporosity of biomedical components, including stents, catheters, guidewires, pacemakers, artificial prostheses, mandrels, endoscopic seals, and silicone rubber devices.
