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.
