Description

Tri-T-Butoxysilanol (CAS NO 18166-43-3) is a versatile organosilicon compound that serves as a key intermediate and coupling agent in advanced material synthesis. Its value lies in its unique chemical structure, featuring both hydrolyzable alkoxy groups and a reactive silanol group, enabling it to form stable bonds with inorganic surfaces and organic polymers. This product is essential for manufacturers in the silicone resins, adhesion promoters, and surface modification sectors seeking to enhance material performance and durability.

Application

• Silicone Resin Precursor: Acts as a critical building block in the synthesis of heat-resistant and weatherable silicone resins for coatings and encapsulants.
• Surface Modification Agent: Used to functionalize inorganic fillers (e.g., silica, glass) to improve dispersion and compatibility in polymer composites.
• Adhesion Promoter: Enhances the bond strength between organic polymers and inorganic substrates in sealants, adhesives, and primers.
• Crosslinking Agent: Employed in the formulation of room-temperature vulcanizing (RTV) silicones and other elastomeric systems.
• Nanomaterial Synthesis: Serves as a silane coupling agent in the sol-gel process for creating hybrid organic-inorganic nanomaterials.
• Water Repellency Treatments: Used to impart hydrophobic characteristics to surfaces in construction and textile applications.
