Parylene Properties

Different varieties, or “chemical variants”, of parylene exhibit very different properties. The diX brand has a purity far exceeding our closest competitor and it was the first, and currently the only, parylene to enter the market with a purity of over 99%. There are only a few manufacturers of parylene in the world, and most have a quality which does not surpass 93%. Our diX parylene has consistently served the needs of companies across many industries, the majority of whom acknowledge the importance of a pure dimer for better coating results. Our Kisco diX brand of parylene is the recognized market leader in product purity.

Kisco’s diX Parylene provides ideal barrier properties. It is Conformal, pin-hole free and can adhere to almost any surface. Parylene is used to uniformly coat and protect virtually any product or component, including diverse substrates such as most types of metal, glass, paper, resin, plastics, elastomers, PCBs, ceramic, rare earth magnets, wire, ferrite and silicone, among others.

Key Properties

• Increase dry film lubricity
• Excellent water/humidity barrier
• High dielectricity, low dielectric constant and low dissipation factor.
• Exceptional in the prevention of rust and corrosion
• Strong chemical/solve resistance (acids, alkalis, solvents, other chemicals)
• Excellent gas barrier properties
• Biocompatible and non-toxic
• No measurable out-gassing
• Thermal stability up to 450°C
• UV resistance

During the coating process, which occurs in KCC’s own branded coating equipment, the resulting film thickness can be uniformly controlled in the micron range to conform to any shape.

There are several varieties of diX parylene, each possessing unique properties. Kisco is constantly adding to its portfolio of products and currently manufactures more variants than anyone in the industry. Eight of our parylene dimer types are presented below. For further detailed information please contact us.

diX C
Our standard and most widely used parylene type. diX C is one of the most robust variants. Thermal stability: 120°C (in Air), 260°C (in oxygen free environments). diX C is used by in many industries including LEDS, Medical, Automotive, Electronics, Aviation/Aerospace, Defense.

diX N
Non-halogen parylene – widely used on silicone rubber products and other elastomers.

Thermal stability: 100°C (in Air), 240°C (in oxygen free environments), dix N is used in Medical and Electronics applications.

diX D
High thermal stability : 140°C (in Air), 260°C (in oxygen free environments) PCBs applications for Automotive, Electronics, Aviation/Aerospace, and Defense applications.

diX HR and SR
High thermal stability and solder resistance. Also offers barrier characteristics similar to diX C. These dimers are used in: LEDS, Medical, Automotive, Electronics, Aviation/Aerospace, Defense.

diX CF

Extreme high thermal stability upto 350°C (in Air) and 450°C (intermittent exposure or in oxygen free environments), diX CF is appropriate for use in LEDS, Automotive, Electronics, Aviation/Aerospace, Defense applications.

diX SF
UV resistance and extreme high thermal stability up to 350°C (in air) and 450°C (intermittent exposure or in oxygen free environments), diX SF is often used in the LEDS, Automotive, Electronics, Aviation/Aerospace, and Defense markets.

diX A and AM

A Bioactive parylene, designed for Medical and Bio-Medical applications. Used to enhance adhesion to DNA, enzymes, and proteins.
