Description

Allyl Octadecyl Methylsilane CAS NO 1114235-08-3 is a specialized organosilicon compound featuring a long-chain alkyl group and a reactive allyl moiety. This unique structure makes it a valuable intermediate for introducing hydrophobic and crosslinkable functionalities into various materials. It is primarily sought after by formulators and researchers in the advanced materials and specialty chemical sectors for developing surface modifiers, release agents, and adhesion promoters.

Application

• Surface Modification Agent: Imparts hydrophobic and oleophobic properties to glass, metals, and mineral surfaces.
• Silicone Intermediate: Serves as a key building block in the synthesis of custom silicone oils, resins, and elastomers.
• Crosslinking Agent: Utilized in polymer systems where the allyl group enables thermal or radical-induced curing.
• Adhesion Promoter: Enhances the bonding between organic polymers and inorganic substrates in composite materials.
• Release Coating Formulation: Used in the development of non-stick coatings for industrial and packaging applications.
• Lubricant Additive: Functions as a friction-reducing and anti-wear additive in specialty lubricants and greases.

Quality Control

Our Allyl Octadecyl Methylsilane is manufactured under a strict quality management system. Every batch undergoes comprehensive analytical testing, including chromatography (GC/HPLC) and spectroscopic methods (NMR, IR), to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing all specifications is provided with each shipment to guarantee it meets your precise application requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent oxidation and moisture absorption. Keep away from heat, sparks, and open flames.
