Parylene Properties

Different varieties, or “chemical variants”,  exhibit a wide range of different parylene 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%. Currently, there are only a few manufacturers of parylene in the world, and most have a purity 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.

Parylene Properties

  • Increase dry film lubricity

  • 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

Kisco_Infographic

Kisco’s diX Parylene provides ideal barrier properties. It is Conformal, pin-hole free and can adhere to almost any surface. In fact, 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.

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

The diX Parylene Spectrum

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. Nine of our parylene dimer types are presented below


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, and Defense.


- Purity > 99%
- Thermal stability 120°C (in Air), 260°C (in oxygen free environments)
- Exceptional gas-barrier
- Meets standards for Mil-I-46058C, IPC-CC-830B, UL94 V-0, FDA, USP, ISO 10993 for medical devices, RoHS

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.


- Thermal stability 100°C (in Air), 240°C (in oxygen free environments)
- Excellent adhesion to Silicone rubbers
- diX N allows for thin coating up to 10um

diX SR/HR

High thermal stability and solder resistance. Also offers barrier characteristics similar to diX C. Thermal stability: 150°C (in Air), 260°C (in oxygen free environments) These dimers are used in: LEDs, Medical, Automotive, Electronics, Aviation and Defense. SR is now a standard parylene for automotive pressure sensor applications.


- Thermal stability 150°C (in Air), 260°C (in oxygen free environments)
- Excellent thermal stability and Pb-free solder reflow applicable
- Meets standards for Mil-I-46058C(dix SR), IP-CC-830B(diX SR) and RoHS (diX SR/HR)

diX NR

Non-halogen and high thermal stability grade. Thermal stability 120°C (in air), 260°C(in oxygen free enviroments). diX HR is often used in the Electronics applications which non-halogen is a requirement.

- Excellent chemical properties

diX SF

UV resistance and extreme high thermal stability up to 300°C (in air) and 450°C (intermittent exposure or in oxygen free environments), diX SF is often used in the LEDs, Automotive, Electronics, Aviation and Defense markets.


- Thermal stability 300°C (in Air), 450°C (in oxygen free environments)
- Increased UV Stability
- Excellent chemical properties

diX A, AM & H

A Bioactive parylene, designed for Medical and Biomedical applications. Used to enhance adhesion to DNA, enzymes, and proteins. These functionalized parylene have the potential to create any type of functionalized surface you require.


- Bio-activity caused by Amino group (-NH2), enable bond with DNA, enzymes and proteins to ENHANCE functions on the surface.
- diX A and AM allow for sub-micron coating as a topcoat on other coatings.
- diX H has bio-activity caused by Carboxyl group and Amino group enhances functions on the surface.
