Characteristics and Advantages
- Hydrophobic, chemically resistant coating with good barrier properties for inorganic and organic media, strong acids, caustic solutions, gases and water vapor
- Low leakage current and a low dielectric constant (average in-plane and out-of-plane: 2.67 parylene N and 2.5 parylene AF-4, SF, HT)
- A biostable, biocompatible coating; FDA approved for various applications
- Dense pinhole free, with thickness above 1.4 nm
- Coating without temperature load of the substrates as coating takes place at ambient temperature in the vacuum
- Highly corrosion resistant
- Completely homogeneous surface
- Stable to oxidation up to 350 °C (Parylene AF-4, SF, HT)
- Low intrinsic thin film stress due to its room temperature deposition
- Low coefficient of friction (AF-4, HT, SF)
- Very low permeability to gases

Famous quotes containing the word advantages:
“There are great advantages to seeing yourself as an accident created by amateur parents as they practiced. You then have been left in an imperfect state and the rest is up to you. Only the most pitifully inept child requires perfection from parents.”
—Frank Pittman (20th century)
