三、产品用途:

3. Uses and applications:

    DETDA是一只十分有效的聚氨酯弹性体扩链剂,尤其适用于RIM(反应注射成型)和SPUA(喷涂聚脲弹性体)上;同时也可用作是聚氨酯弹性体以及环氧树脂的芳香族二胺固化剂,用于浇注、涂料、RIM及胶黏剂,也是聚氨酯及聚脲弹性体的扩链剂。

    DETDA是一种位阻型芳香族二胺,?#19968;?#21644;甲基的位阻作用使得其活性比甲苯二胺(TDA)低得多。它与聚氨酯预聚体的反应速度比DMTDA快数倍,比MOCA快约30倍。主要用于RIM聚氨酯体系以及喷涂聚氨酯(脲)弹性体涂料体系,具有反应速度快,脱模时间短、初始强度高、制品耐水解、耐热等优点。另外该品还可用作弹性体、润滑剂及工业油脂的抗氧剂,以及化学合成中间体。

  DETDA is a very effective polyurethane elastomer chain expansion agent, especially for the RIM (reaction injection molding) and SPUA (spray polyurea elastomer): also can be used as polyurethane elastomer and epoxy resin aromatic diamine curing agent, used for casting, coating,RIM and adhesive, but also is a polyurethane and polyurea elastomer chain extension agent.
  DETDA is a type of aromatic diamine, ethyl and methyl groups,  which makes the activity of is much lower than that of TDA. The reaction rate with polyurethane prepolymer several times faster than DMTDA, about 30 times faster than MOCA. Mainly used in RIM polyurethane system and spray polyurethane (polyurea) elastomer coating system, with a fast reaction rate, short release time, high initial strength, product resistance to hydrolysis,heat and so on.In addition to the product can also be used as elastomer, lubricants and industr ial oil antioxidant, and chemical intermediates.

四、包装储运:

4. Packaging and transport:

    包装为1000KG/IBC桶、200KG铁桶或ISOTANK(国?#26102;曜技?#35013;箱),具体可按照客户要求采用特殊包装。

    Packaging for 1000KG/IBC barrels,200kg drums or ISOTANK, the special packaging in accordance with the  requirements  of customers.

    不要放置在室外,避光储存,避免长时间存放在高温条件下。

五、贮运

5.Storage:

    Stacked in a cool/dry/ventilated place,keep away from heat/fire, to prevent the direct sunlight, to avoid  high temperature, do not sharp object collision damage.
