Parylene F/VT-4 (CAS No. 1785-64-4)

Parylene is a chemical compound applied to substrates using chemical vapor deposition (CVD). Because Parylene coating deposits onto the surface molecule by molecule, it forms a defect and pinhole-free coating with excellent conformality. Parylene resists chemicals, can protect against caustic substances, acids, and corrosion, and more. Unlike conventional conformal coatings, Parylene is ultra-thin, providing superior coverage at 50% thickness. Its adaptability is enhanced by the fact that several types of Parylene coating exist, all suited for various industrial applications.

Feature and advantages:

Parylene F is a type of parylene dimer, which is a chemical used to create thin-film coatings. Parylene F is different from other types of parylene in that it has a high level of fluorine content, which gives it unique properties, including:

1.Hydrophobicity: Parylene F is highly resistant to water and other liquids, making it an excellent barrier against moisture and chemicals. This property makes it ideal for use in harsh environments.
2.High Dielectric Strength: Parylene F has excellent electrical insulation properties, making it useful for electronic applications. It is often used to protect and insulate sensitive electronics components from the environment.
3.High Thermal Stability: Parylene F is stable at high temperatures, making it suitable for use in applications where high heat is a concern.
4.Biocompatible: Parylene F is biocompatible, which means it is safe for use in medical devices and implants.
5.Low Surface Energy: Parylene F has a low surface energy, which makes it resistant to adhesion. This feature makes it useful in applications where sticking or bonding is a concern.

 

Overall, parylene F offers exceptional barrier properties against moisture and chemicals, excellent electrical insulation, and is stable at high temperatures, making it a popular choice in a wide range of industries, including aerospace, electronics, and medical device manufacturing.

 

Highlights:

• Parylene-VT4 exhibits a low dielectric constants and high thermal stability.
