Description
High-purity Parylene dimers for use in vapour deposition (CVD) coating processes. Available in Parylene C, D, N, F and AF-4 grades, with volume-based pricing to support prototype work through to full production.
Parylene dimers are the solid precursor materials used in the chemical vapour deposition process to produce conformal Parylene coatings. During deposition, the dimer is vaporised, cracked into a monomer gas, and polymerised onto component surfaces to form a uniform, pinhole-free coating.
SCH supplies high-purity Parylene dimers as part of our wider range of Parylene products, where consistent material quality is critical to maintaining coating performance, deposition efficiency, and long-term reliability.
For a detailed overview of Parylene dimer grades, material properties, and typical applications, see our Parylene Basics: Grades, Properties & Uses guidance.
This product is available in multiple Parylene grades, each offering different material properties to suit specific application requirements:
- Parylene C β general-purpose coating with excellent moisture and chemical barrier properties
- Parylene D β enhanced thermal stability for higher temperature operating environments
- Parylene N β lower dielectric constant for high-frequency and RF applications
- Parylene F (VT-4) β high-temperature performance with improved oxidative stability
- Parylene AF-4 β ultra-low dielectric constant for advanced high-frequency and aerospace applications
Volume-based pricing options provide flexibility for R&D, low-volume production, and full-scale manufacturing. Selected grades or pack sizes may be supplied on a request-for-quotation basis depending on availability and application requirements.
Selecting the correct Parylene dimer grade is essential to achieving the desired coating performance. Factors such as operating temperature, dielectric properties, chemical exposure, and regulatory requirements should be considered during material selection.
Appropriate masking for Parylene coating is essential to protect connectors, test points, and defined keep-out areas during deposition.
If you do not operate in-house deposition equipment, SCH also provides Parylene coating services using production-qualified systems.
