Description

Silanetriol, Octyl- CAS NO 31176-12-2 is a reactive organosilicon compound featuring a silanetriol head group and a hydrophobic octyl chain. This unique structure makes it a versatile intermediate and surface-modifying agent, crucial for imparting water repellency and improving adhesion between organic and inorganic materials. It is essential for formulators and manufacturers in the coatings, sealants, and advanced materials sectors seeking to enhance product performance and durability.

Application

• As a key coupling agent and crosslinker in silicone resin and rubber formulations.
• Surface modification of inorganic fillers (e.g., silica, glass) to improve dispersion in polymer matrices.
• Hydrophobic agent in protective coatings, sealants, and water-repellent treatments.
• Intermediate for the synthesis of more complex functional silanes and siloxanes.
• Adhesion promoter in primers and coatings for metals, glass, and minerals.
• Component in sol-gel processes for creating hybrid organic-inorganic materials.
• Potential use in the modification of nanoparticles for specialized composite applications.

Quality Control

Our Silanetriol, Octyl- is produced under stringent quality management protocols. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency. A Certificate of Analysis (COA) detailing specific results for key parameters is provided with every shipment to support your quality assurance and regulatory needs.

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, containers should be kept tightly sealed under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation. Recommended storage temperature is 2-8°C for long-term stability.
