Features Of Momentive A-Link 15 Gamma-Isocyanatopropyltrimethoxysilane

  1. Bifunctional silane coupling agent with reactive isocyanate (–NCO) and hydrolyzable methoxy (–OCH₃) groups.

  2. Enables covalent bonding between organic polymers (e.g., polyurethanes, epoxies) and inorganic substrates (e.g., glass, metals, minerals).

  3. Improves adhesion, moisture resistance, and mechanical durability in hybrid composite systems.

  4. Offers enhanced shelf stability compared to conventional isocyanatosilanes due to optimized molecular structure and purification.

  5. Compatible with common solvents including acetone, ethyl acetate, and aromatic hydrocarbons for easy formulation integration.

Typical Applications Of Momentive A-Link 15 Gamma-Isocyanatopropyltrimethoxysilane

  1. Adhesion promoters in polyurethane-based sealants and structural adhesives for automotive glazing.

  2. Surface modifier for silica and glass fillers in high-performance elastomers and thermoplastic composites.

  3. Hybrid crosslinker in moisture-curing silicone-polyurethane hybrid coatings and encapsulants.

  4. Interfacial enhancer in fiber-reinforced polymer (FRP) composites for wind turbine blades and aerospace components.

  5. Functional additive in UV- and thermal-curable hybrid resins for advanced electronics encapsulation.
