Key Properties of SCS Parylene Coatings
SCS Parylene conformal coatings are ultra-thin and pinhole-free and offer exceptional moisture, chemical and dielectric barrier properties, along with thermal and UV stability and dry-film lubricity. These characteristics make Parylene coatings the ideal choice for a variety of applications in the medical device, electronics, automotive, defense and aerospace industries.
Parylene Variants and Their Unique Benefits
Each Parylene variant offers distinct benefits tailored to specific engineering needs. The following are commercially available Parylene variants:
Parylene N
Parylene N is a completely linear, highly crystalline material, known for its low dissipation factor, high dielectric strength and low dielectric variant across frequencies. Its exceptional crevice penetration makes it a reliable choice for intricate applications.
Parylene C
Parylene C is a versatile variant that combines excellent electrical and physical properties with low permeability to moisture and corrosive gases. It is suitable for a broad range of applications, from electronics to defense.
Parylene D
Similar to Parylene C but with enhanced thermal stability, Parylene D is stable in slightly higher temperatures, making it an ideal protective coating for applications that experience greater temperature fluctuation.
Parylene HT®
Parylene HT® excels in protecting components that must survive high-temperature environments. The coating endures short-term exposure up to 450°C and provides long-term UV stability as well as features the lowest coefficient of friction and highest penetration ability among Parylene variants.
ParyFree®
ParyFree® is a halogen-free variant that provides increased mechanical and electrical coating properties while maintaining the advanced barrier features of Parylene C. It’s designed for industries requiring compliance with global environmental standards.
Parylene C-UVF®
For applications where verification of a coating is critical, Parylene C-UVF® includes a special compound that fluoresces under black light, confirming the presence of Parylene coating without compromising any of its essential properties.
microRESIST® Antimicrobial Parylene Technology
microRESIST® combines the biocompatibility of Parylene with antimicrobial properties, effectively eliminating harmful microorganisms on coated medical devices. This technology provides reliable protection, demonstrating over 5 Log reduction on 14 common microorganisms.
