Parylene Dimers – High-Purity Materials for Reliable Coatings
Overview
SCH Services Ltd supplies high-purity Parylene dimers (N, C, D, AF-4) for consistent deposition across commercial Parylene coating systems. Every batch is fully traceable, vacuum-sealed and supplied with supporting documentation for regulated sectors including aerospace, medical and electronics.
We support both in-house coaters and subcontract users with the right dimer grade, pack size and logistics — from R&D quantities to full production volumes.
If you need more than raw material supply, SCH can also support dimer selection, implementation planning, equipment setup, training and long-term process stability through our wider turnkey Parylene platform.
High-purity Parylene dimer supply supporting stable deposition, reliable polymerisation and traceable process control.
Why Buy Parylene Dimers from SCH?
- High Purity & Consistency: tightly controlled production with batch QC and full documentation for regulated sectors.
- Proven in Real Processes: the same dimer grades are used daily in SCH’s own Parylene coating services.
- Flexible Supply Options: standard 500 g and 1 kg packs with custom sizes and private-label options available.
- Technical Support: guidance on grade selection, handling, storage and process optimisation from experienced Parylene engineers.
- Global Logistics: established supply into Europe, North America and Asia with export paperwork and support.
Need More Than a Material Supplier?
Choosing the right dimer is only one part of a successful Parylene process. Deposition rate, grade qualification, equipment sizing, throughput planning and operator knowledge all affect long-term coating performance.
🧪 Explore the Bigger Picture – SCH can support the full route from dimer selection through to equipment, training and implementation.
Independent SGS Verification – SCH Parylene Materials
Independent SGS testing throughout 2025 confirmed that all SCH Parylene materials (including Parylene N, C, D and fluorinated F/AF-4) contain no detectable Substances of Very High Concern (SVHCs), polycyclic aromatic hydrocarbons (PAHs), or PFOS/PFOA compounds to ppm-level detection limits.
Applicable fluorinated grades also meet full RoHS 2.0 (2015/863) compliance. This independent verification supports ultra-high-purity feedstock, stable polymerisation and consistent coating performance across the SCH Parylene range.
Verified by SGS-CSTC Standards Technical Services Co., Ltd – full test reports available on request (2025).

Available Parylene Dimer Grades
Parylene N Dimer
Base chemistry with excellent dielectric strength and deep penetration for complex geometries.
Parylene C Dimer
Most widely used grade; monochloro-substituted for strong moisture and chemical resistance.
Parylene D Dimer
Dichloro variant offering improved thermal stability versus Parylene C.
Parylene F / AF-4 Dimer
Fluorinated precursor with very low dielectric constant and high temperature capability.

Parylene Dimer FAQs
Which Parylene dimer should I choose?
As a rule of thumb: N for penetration and high dielectric strength, C for moisture and chemical resistance, D for higher thermal stability, and AF-4 for very low dielectric constant and high temperature capability. If you are unsure, SCH can review your application and help you choose the most suitable grade.
What pack sizes are available?
Standard packs are 500 g and 1 kg. Custom sizes and private-label supply may also be available depending on grade and quantity.
How should Parylene dimers be stored?
Keep dimers sealed in their original containers, away from heat and moisture. Follow the supplied handling guidance to maintain quality and shelf life.
Are your dimers compatible with my deposition system?
Yes — our high-purity grades are intended for use across major commercial Parylene systems. If you tell us your make and model, we can help confirm suitability and discuss grade selection.
Can SCH support grade qualification as well as supply?
Yes. SCH can support material selection, application review, process planning and broader implementation support if you are qualifying a new grade or setting up in-house coating capability.
