Description

Pss-Octa(2-Trichlorosilylethyl) Substit& CAS NO 214675-88-4 is a highly functionalized, multi-armed silane coupling agent featuring eight reactive trichlorosilyl groups. This compound is critical for creating robust, covalently bonded interfaces between inorganic substrates and organic polymers or coatings. It is primarily needed by manufacturers in the advanced materials, specialty adhesives, and high-performance composites sectors seeking to enhance surface adhesion, durability, and chemical resistance.

Application

• Surface Priming for Inorganic Materials: As a multi-dentate coupling agent for glass, silica, metals, and ceramics to improve polymer adhesion.
• Crosslinking Agent in Hybrid Materials: For synthesizing highly cross-linked siloxane networks and organic-inorganic hybrid (OIH) polymers with tailored mechanical properties.
• Nanoparticle Functionalization: To modify the surface of nanoparticles (e.g., SiO2, TiO2) for better dispersion and compatibility in polymer matrices.
• Adhesive and Sealant Formulations: Enhancing the bond strength and moisture resistance of high-performance silicone and polysulfide-based systems.
• Fiber Reinforced Composites: Treating glass or carbon fibers to optimize the fiber-matrix interface in composite materials.
• Protective Coatings: As a key component in formulating chemically resistant and anti-corrosion coatings.
• Chromatography Stationary Phases: Potential use in the synthesis of specialized silica-based stationary phases for HPLC.
• Precursor for Dendrimer Synthesis: Serving as a core molecule for building complex, three-dimensional dendritic structures.

Quality Control

Our Pss-Octa(2-Trichlorosilylethyl) Substit& CAS NO 214675-88-4 is produced under stringent quality management protocols. Each batch undergoes rigorous analytical testing, including spectroscopic identification and purity assessment, to ensure consistency and compliance with customer specifications. Certificates of Analysis (COA) detailing specific batch results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere (e.g., nitrogen or argon) to prevent hydrolysis and degradation. Recommended storage temperature is 2-8°C for extended stability.
