Material Notes:
Parylene HT is a polymer of para-xylylene with the alpha hydrogen atoms of the N dimer replaced with fluorine. This variant of Parylene is useful in high temperature applications (short term up to 450°C) and those in which long-term UV stability is required. Parylene HT also has a low coefficient of friction and dielectric constant, and a high penetrating ability.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) .
