Hexadecyltrimethoxysilane | Super-Hydrophobic Silane | CAS 16415-12-6
Overview
Hexadecyltrimethoxysilane (HDTMS) is an advanced, clear to slightly yellowish monomeric alkylsilane distinguished by its ultra-long 16-carbon alkyl chain. When applied to surfaces or used as a filler modifier, the methoxy groups rapidly hydrolyze to bond securely with inorganic substrates, while the massive 16-carbon chain projects outward. This unique molecular architecture creates extreme surface tension reduction, delivering the ultimate “Lotus Effect” (super-hydrophobicity) for self-cleaning and anti-graffiti applications.
Product Description
Hexadecyltrimethoxysilane (HDTMS) is an advanced monomeric alkylsilane distinguished by its ultra-long 16-carbon alkyl chain. When applied to surfaces, the methoxy groups bond securely with inorganic substrates, while the massive 16-carbon chain projects outward. This unique molecular architecture creates extreme surface tension reduction, delivering the ultimate "Lotus Effect" (super-hydrophobicity) for self-cleaning and anti-graffiti applications.
At Shandong Yinglang Chemical Co., Ltd., established in 2016, we supply bulk volumes of Premium Hexadecyltrimethoxysilane to the world's most innovative architectural coating formulators and advanced nanomaterial manufacturers. Shipped globally as completely safe Non-Dangerous Goods, our HDTMS empowers your formulations to achieve extreme water contact angles, offering unparalleled protection against moisture, dirt, and chemical ingress.
For premium anti-graffiti coatings and high-end surface modifications, strict purity is required. Typical specifications:
| Purity (HDTMS) | ≥ 95.0% |
|---|---|
| Color (Pt-Co) | ≤ 30 |
| Density (at 20°C) | 0.880 - 0.900 g/cm³ |
| Refractive Index (at 20°C) | 1.430 - 1.440 |
| Moisture | ≤ 0.1% |
- Super-Hydrophobic Coatings: The core active ingredient for creating "Lotus Effect" surfaces on architectural glass and concrete, allowing water to form perfect spheres that roll off, carrying away dust.
- Anti-Graffiti Sealers: The dense 16-carbon shield prevents spray paints from penetrating porous stone or brick, allowing for easy, chemical-free wash-off.
- Premium Mineral Modifier: Deeply coats TiO2 and ATH nanoparticles, dramatically improving their dispersion in non-polar plastics (PE/PP).
- Textile Waterproofing: Formulated into advanced DWR treatments for outdoor gear.
Achieving extreme water repellency requires maximizing the Water Contact Angle (WCA). While standard 8-carbon silanes provide excellent baseline waterproofing, Yinglang Chemical's 16-carbon Hexadecyltrimethoxysilane pushes surface tension to the absolute limit. By forming a highly ordered, tightly packed hydrophobic monolayer, it routinely enables contact angles exceeding 110°, turning ordinary building materials into self-cleaning, ultra-durable smart surfaces.
As a highly stable liquid with an extremely high flash point (>110°C), we offer cost-effective and safe bulk packaging for global ocean freight:
- 1000 KG IBC Totes (Highly recommended for coating formulators).
- 180 KG / 190 KG Heavy-duty Steel or PE Drums (Tightly sealed and N2-blanketed).
- ISO TANKS (20 MT) available for continuous industrial procurement.

FAQ
Q1: What documents and certifications do you provide?
A Standard shipment includes COA (Certificate of Analysis) and MSDS (SDS). We also provide ISO 9001 certification and support third-party inspections like SGS or BV upon request.
Q2: Do you provide custom synthesis or formulation services?
A Yes. If you have specific purity requirements or a unique formulation, our R&D team can provide custom synthesis and adjust the stabilizers/inhibitors to meet your technical specifications.
Q3: What are your terms of payment?
A
For Orders ≤ $1,000: 100% in advance.
For Orders > $1,000: 30% T/T in advance, and the balance before shipment or against the copy of B/L. Irrevocable L/C at sight is also acceptable for bulk orders.
Q4: How long is your price valid?
A Chemical prices fluctuate due to the changes in raw material costs and exchange rates. Please contact our sales team for the latest real-time quotation.
Q5: What packaging and shipping ports are available?
A
We normally ship from Qingdao, Shanghai, or Ningbo.
Standard packaging includes 200kg Drums or 1000kg IBC Totes. We ensure strict safety compliance for both general and hazardous chemical cargoes.
Q6: It's my first time importing chemicals — can you help?
A Absolutely. Importing chemicals requires specific documentation. Our experienced logistics team will assist you with the entire process, including handling customs clearance documents and arranging the most suitable shipping method.
