PARYLENE COATING APPLICATIONS
Parylene has been the coating of choice for mission critical aviation, aerospace and military applications for decades because of its unique combination of properties. These coating capabilities are equally important for industrial and commercial coating applications. CWST Coating has a record of leadership in Parylene process development and carefully managed coating production across a wide spectrum of manufacturing applications.
Parylene conformal coating film seals surfaces, making them resistant to contaminants, moisture, petro chemicals,corrosives, gases, acids and alkalis. While its barrier properties are unmatched, Parylene adds very minimal mass to coated surfaces and contributes no cure or thermal expansion forces to threaten delicate components. Parylene has exceptional tensile and yield strength, and is used to protect many substrate types from glass and metal to ceramics, plastics and even elastomers.
CWST supplies Parylene raw material in multiple forms, each suited to particular performance requirements. Automated production systems in our coating centers are designed to meet customer needs with maximum vacuum deposition effectiveness and process accuracy. CWST holds multiple patents for innovative, proprietary system designs that enhance production quality as well as efficiency.
