MT -4 form TAN YUN

MT-4
 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
Item Index
Acid value, mg KOH/g ≤2.0
Moisture, % (m/m) ≤0.5
Appearance Red-brown transparent viscous liquid
 3. Uses:MT-4 has been used as cross-linking agent and curing agent on the cladding layers of missile resin to heighten the capabilities of elasticity and ballistic in propellant. It works well to improve elongation rate and cryogenic performances of the AP-based oxidizer in HTPB composite solid propellants.
 4. Safety instructions: Toxic by skin. Operation carefully must be installed with rubber gloves to avoid contacting with skin, eyes and clothing.
 5. Package: Wooden box with two plastic casks of 10 kg net, 20 kg net each.
 6. Storage: Nitrogen sealed. Store at cool and ventilate. Forbid to heat and exposure. Shelf life of 12 months, if expire, still used if up to standard through retest.
 7. Transportation: Avoid inversion, sunlight and crash.
