Momentive Silquest Y-962 1,2-Bis(trimethoxysilyl)ethane

Momentive Silquest Y-962 is a bifunctional alkoxysilane coupling agent—1,2-bis(trimethoxysilyl)ethane—designed to enhance adhesion between organic polymers and inorganic substrates like glass, metals, or fillers. It improves mechanical strength, moisture resistance, and composite durability in sealants, coatings, and reinforced plastics. The ethane bridge offers superior hydrolytic stability versus silanes with longer spacers. Widely used in silicone-modified systems and RTV formulations.

Features Of Momentive Silquest Y-962 1,2-Bis(trimethoxysilyl)ethane

  1. Bifunctional silane coupling agent with two hydrolyzable trimethoxy groups per molecule.

  2. Provides enhanced covalent bridging between organic polymers and inorganic substrates (e.g., glass, silica, metals).

  3. Offers superior hydrolytic stability compared to trialkoxysilanes with shorter alkyl spacers.

  4. Enables improved mechanical properties—including tensile strength, modulus, and moisture resistance—in filled composites.

  5. Compatible with a broad range of resins including epoxies, polyurethanes, acrylics, and phenolics.

Typical Applications Of Momentive Silquest Y-962 1,2-Bis(trimethoxysilyl)ethane

  1. Reinforcement of silica-filled silicone rubber for high-performance seals and gaskets.

  2. Surface modification of nanosilica and fumed silica in adhesive and sealant formulations.

  3. Enhancement of glass fiber–reinforced thermoset composites (e.g., wind turbine blades, automotive parts).

  4. Moisture-cure primers and adhesion promoters for metal and glass substrates.

  5. Stabilization of colloidal silica dispersions used in coatings and catalyst supports.
