Momentive Silquest A-1160 Gamma-Ureidopropyltriethoxysilane

Momentive Silquest A-1160 is a gamma-ureidopropyltriethoxysilane coupling agent from the Silquest series, designed to enhance adhesion between organic polymers and inorganic substrates like glass, metals, or minerals. It improves dispersion, moisture resistance, and mechanical performance in composites, sealants, and coatings through dual-reactive functionality—hydrolyzable ethoxy groups and a ureido moiety.

Features Of Momentive Silquest A-1160 Gamma-Ureidopropyltriethoxysilane

  1. Gamma-ureidopropyl functional group enables strong hydrogen-bonding interactions with polar polymers and fillers.

  2. Triethoxysilane hydrolysis yields reactive silanol groups for robust covalent bonding to inorganic surfaces (e.g., glass, silica, metals).

  3. Enhances interfacial adhesion and dispersion stability in filled polymer systems without requiring acidic or basic catalysts.

  4. Offers superior hydrolytic stability compared to aminosilanes with primary amine functionality, reducing premature condensation.

  5. Compatible with ambient-cure and heat-cure formulations across thermoset and thermoplastic matrices.

Typical Applications Of Momentive Silquest A-1160 Gamma-Ureidopropyltriethoxysilane

  1. Adhesion promotion in automotive sealants and structural adhesives for glass-to-metal bonding.

  2. Surface modification of silica and clay fillers in high-performance rubber compounds (e.g., tires, industrial hoses).

  3. Functional additive in UV-curable coatings and inks to improve substrate wetting and crosslink density.

  4. Interfacial coupling agent in fiber-reinforced composites using E-glass or basalt fibers.

  5. Performance enhancer in moisture-cure polyurethane and silicone hybrid sealants.
