Features Of Momentive Silquest A-1170 Bis(gamma-trimethoxysilylpropyl)amine

  1. Bifunctional silane coupling agent with dual trimethoxysilyl groups and a primary amine functionality.

  2. Enables strong covalent bonding between organic polymers and inorganic substrates such as glass, metals, and minerals.

  3. Enhances hydrolytic stability of silane-treated surfaces due to the electron-donating effect of the amine group.

  4. Improves adhesion, moisture resistance, and mechanical performance in filled composites and adhesive formulations.

  5. Compatible with aqueous and solvent-based systems, supporting versatile processing across coating, sealant, and composite manufacturing.

Typical Applications Of Momentive Silquest A-1170 Bis(gamma-trimethoxysilylpropyl)amine

  1. Adhesion promoters in automotive and industrial adhesives and sealants.

  2. Surface treatment for silica, glass fibers, and mineral fillers in thermoset and thermoplastic composites.

  3. Performance additive in high-durability architectural and industrial coatings.

  4. Hybrid sol-gel precursors for functionalized coatings and corrosion-inhibiting primers.

  5. Reinforcement aid in rubber compounds, especially for silica-reinforced tire treads.
