Description

[(3,7-Dimethyl-6-Octenyl)Oxy]Dimethoxymethylsilane is a specialized organosilicon compound, a silane coupling agent featuring a citronellyl-derived alkoxy group. This product matters for its unique ability to modify surfaces and interfaces, providing enhanced compatibility between organic polymers and inorganic substrates. It is primarily needed by manufacturers in the silicone rubber, adhesive, and sealant industries, as well as in the production of specialty coatings and surface treatments where improved adhesion and hydrophobic properties are critical.

Application

• As a key coupling agent and crosslinker in the production of high-performance silicone elastomers and RTV (Room Temperature Vulcanizing) silicone rubbers.
• To improve the adhesion and moisture resistance of sealants and adhesives, particularly in construction and automotive applications.
• As a surface treatment agent for fillers (e.g., silica, minerals) to enhance their dispersion and compatibility within polymer matrices.
• In the formulation of release coatings and anti-adhesive layers for industrial and packaging materials.
• As a hydrophobic modifier for surfaces in textile, paper, and leather treatment processes.
• For the synthesis of more complex organosilicon intermediates used in pharmaceuticals and agrochemicals.

Quality Control

Our [(3,7-Dimethyl-6-Octenyl)Oxy]Dimethoxymethylsilane is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including GC (Gas Chromatography) for purity and identity confirmation, to ensure it meets precise specifications. Certificates of Analysis (COA) documenting all critical parameters are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, containers must be kept tightly sealed after opening to prevent degradation from atmospheric moisture. Keep away from strong acids, bases, and oxidizing agents.
