Name: Momentive Silquest A-1106 Gamma-Aminopropylsilsesquioxane
Brand: Guangzhou Eric Wei Chemical Co., Ltd.

Features Of Momentive Silquest A-1106 Gamma-Aminopropylsilsesquioxane

Hybrid molecular architecture combining reactive gamma-aminopropyl functionality with a cage-like silsesquioxane core.
Enhanced thermal and hydrolytic stability compared to conventional aminosilanes due to the robust Si–O–Si cage structure.
Reduced volatility and improved handling safety versus low-molecular-weight aminosilane coupling agents.
Offers dual reactivity: primary amine group for epoxy, isocyanate, or aldehyde reactions, and hydrolysable silanol precursors for inorganic surface bonding.
Enables precise nanoscale interface engineering in hybrid organic–inorganic composites without phase separation.

Typical Applications Of Momentive Silquest A-1106 Gamma-Aminopropylsilsesquioxane

Reinforcement of silica- or clay-filled epoxy composites for aerospace and electronics encapsulation.
Surface modification of nanoparticles (e.g., SiO₂, TiO₂) used in UV-curable coatings and inks.
Functional additive in high-performance polyurethane adhesives and sealants requiring humidity resistance.
Co-crosslinker in silicone–epoxy hybrid resins for LED packaging and thermal interface materials.
