Welcome to SAE Engineering
HX‑752
HX‑752 (CAS No. 7652‑64‑4) is a specialized aziridine‑based bonding agent with the chemical formula C14H16N2O2. It is primarily used in military solid composite propellants to improve adhesion between oxidizers and the polymer binder matrix. HX‑752 appears as a pale yellow liquid and enhances mechanical strength and thermal stability, often replacing bonding agents that release ammonia. Due to its reactivity, it requires cold storage at approximately −18°C.
Key Details:
Chemical Formula: C14H16N2O2
Chemical Name: 1,1′‑Isophthaloylbis(2‑methylaziridine)
Description: Clear to pale amber, viscous liquid. It is highly reactive to heat and acids and must be stored below −18°C to prevent exothermic polymerization.
Common Uses:
- Composite Propellants: Functions as a bonding agent to improve adhesion between oxidizers and binders, enhancing mechanical integrity and performance.
- Polymer Materials: Used to enhance adhesion and physical properties in specialized polymer systems.
Safety / Handling: Toxic upon skin contact and requires specialized handling procedures. HX‑752 is considered a potential carcinogen and must be stored and handled under controlled conditions using appropriate personal protective equipment.
