Description

Tris(Vinyldimethylsiloxy)Methylsilane is a specialized organosilicon compound with a unique multi-functional structure. This chemical is valued for its ability to act as a reactive crosslinking agent and a precursor for silicone-based polymers and hybrid materials. It is essential for manufacturers in the silicone elastomer, adhesive, and advanced material coating sectors seeking to enhance product durability and performance. The compound, CAS NO 60111-52-6, is a key intermediate for creating materials with tailored mechanical and surface properties.

Application

• Crosslinking agent in the production of addition-cure silicone rubbers and high-consistency rubber (HCR).
• Key intermediate for synthesizing silicone resins with improved thermal stability and adhesion properties.
• Modifier for surface treatments and coatings to impart hydrophobicity and release characteristics.
• Precursor in the manufacture of specialty silicone fluids and gels for electronic encapsulation.
• Component in the formulation of pressure-sensitive adhesives (PSAs) and sealants.
• Building block for creating hybrid organic-inorganic materials (ORMOSILs) for optical and protective applications.
• Used in research and development for novel polymer networks and composite materials.

Quality Control

Our Tris(Vinyldimethylsiloxy)Methylsilane is produced under stringent quality management systems. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation via FT-IR and NMR spectroscopy, to ensure it meets precise technical specifications. Certificates of Analysis (COA) detailing all test results are provided with every shipment to guarantee batch-to-batch consistency and reliability for your critical formulations.

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/59-77°F). This product is hygroscopic (moisture-sensitive) and should be kept under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Keep away from heat, sparks, and open flame.
