Description

Di-T-Butoxydimethoxysilane, Tech-95 CAS NO 6852-04-6 is a high-purity organosilicon compound widely used as a versatile coupling agent and surface modifier. Its bifunctional alkoxy groups enable effective crosslinking and adhesion promotion between organic polymers and inorganic substrates. This technical-grade material is essential for manufacturers in the silicone polymer, coatings, and advanced materials industries seeking to enhance product performance and durability.

Application

• As a coupling agent in silicone resin and rubber formulations to improve mechanical properties.
• As a surface treatment agent for fillers (e.g., silica, glass fibers) to enhance dispersion and compatibility in polymer matrices.
• As a key intermediate in the synthesis of more complex organosilane derivatives and functional materials.
• In the production of moisture-curable sealants and adhesives, where it contributes to crosslinking and stability.
• For hydrophobic coating applications on various surfaces, including glass and metals.
• As a crosslinking agent in specialty polymer networks requiring controlled reactivity.
