                      Material Notes:
                      Parylene D is a polymer of para-xylylene modified by the substitution of chlorine atoms for two of the aromatic hydrogen atoms. Parylene D is similar in properties to Parylene C with the added ability to withstand slightly higher use temperatures.SCS Parylene conformal coatings are ultra-thin, pinhole-free polymer coatings that provide a number of high-value surface treatment properties such as excellent moisture, chemical and dielectric barrier properties, thermal and UV stability, and dry-film lubricity. Parylene coatings are used in a number of applications throughout the medical device, electronics, automotive, military and aerospace industries.Information provided by Specialty Coating Systems (SCS) .
