Features Of Momentive A-1160 Gamma-Ureidopropyltriethoxysilane

  1. Unique gamma-ureido functional group enables strong covalent bonding to both organic polymers and inorganic substrates.

  2. Triethoxysilane hydrolysis yields reactive silanol groups for robust crosslinking and surface modification.

  3. Enhances adhesion, durability, and moisture resistance in filled composites and adhesive formulations.

  4. Improves dispersion stability of fillers (e.g., silica, glass, minerals) in polar and non-polar polymer matrices.

  5. Offers superior compatibility with epoxy, polyurethane, acrylic, and rubber-based systems.

Typical Applications Of Momentive A-1160 Gamma-Ureidopropyltriethoxysilane

  1. Epoxy resin composites for electrical encapsulation and structural adhesives.

  2. High-performance polyurethane coatings and sealants requiring enhanced substrate adhesion.

  3. Silica-reinforced rubber compounds (e.g., tire treads, industrial hoses).

  4. Mineral-filled thermoplastics and thermosets to improve mechanical strength and interfacial bonding.

  5. Primer formulations for glass, metal, and ceramic surfaces prior to coating or bonding.
