Executive standard: Q/TY·J08.04-2015
1. Physical and chemical properties:
1.1 Odor: Foul smell with rotten grass
1.2 Solubility: Freely dissolved in organic solvents, such as methylene dichloride, chloroform, ethyl ether, etc. Slightly soluble in water.
1.3 Stability: Decomposing temperature is greater than 100℃. It will be decomposed in any acid. The polymerization occurs when contacted with acidic material or impurities containing active hydrogen. The copolymerization and cross-linking can be also taken place when contacted with the compounds containing two or more than two active hydrogen.
2. Technical indexes:

| Appearance |
Red-brown transparent viscous liquid |
3. Application：MT-4 has been used as the cross-linking agent and bonding agent to increase the elongation and improve low-temperature mechanical properties in AP/HTPB composite solid propellant. MT-4 is the chemical modified product of MAPO.
4. Safety instructions: Toxic by skin. Rubber gloves, respirator and eye protection must be used during operations in case of skin contact, eyes contact.
5. Packing: Two plastic casks in a wooden case. Net Weight: 10 kg/cask; 20 kg/case.
6. Storage: Nitrogen sealed. Store at cool and ventilate. Forbid to heat and exposure. The shelf life is 12 months after manufacturer date. It is still available if retest result is qualified after expire date
7. Transportation: Keep upright when transported, avoid violent collision and exposure.
