Application

Parylene C, a chlorinated poly(para-xylylene) polymer, is widely employed as a biocompatible, corrosion-resistant coating, as a packaging material, and as an optically transparent material. 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. These properties make Parylene coatings the ideal choice for a number of applications throughout the medical device, electronics, transportation, defense and aerospace industries.

Parylene C dimer is used to add a barrier against moisture and gases. Parylene C is known for its excellent adhesion to various substrates, offering exceptional protection against environmental elements. It is also used as a dielectric coating in microelectronic applications.

The moisture-resistant Parylene C is similar to Parylene N in that it contains a carbon structure. However, for each molecule, it possesses one chlorine atom in place of a hydrogen atom. As a conformal coating, Parylene C provides a protective barrier for printed circuit boards. Parylene C also offers excellent protection against corrosive substances due to its low permeability. Like other types, Parylene C is added to a substrate using the chemical vapor deposition process.
