Pentamethyldiethylenetriamine is generally obtained by N-methylation of diethylenetriamine as raw material, and the methylation methods are formic acid/formaldehyde method, formaldehyde hydrogenation method, etc.
Properties and Uses:
Pentamethyldiethylenetriamine is a highly active and strong foaming polyurethane catalyst, which can also be used to balance the overall foaming and gelation reaction. It is widely used in all kinds of polyurethane rigid foam, including polyisocyanuric acid sheet rigid foam, and also improves foam flow, so it can improve product production process and product quality.

Storage and transportation
When transporting Catalyst, it should be strictly protected from rain and staining, carefully and gently stored to prevent leakage from collision with hard objects. When storing Catalyst, it should be stored at room temperature in a ventilated and dry warehouse, avoiding humid environment, and the storage temperature should be kept below 25℃, avoiding sunlight as much as possible, and away from water and heat sources. To prevent moisture absorption and oxidation, it is recommended to fill the container with nitrogen.
Under proper storage conditions, the shelf life is 6 months from the date of manufacture, after which the product can be used after retesting.
Catalyst is somewhat toxic and should be rinsed with soapy water promptly after contact with skin. Staff can wear eye protection or safety glasses for the purpose of eye protection. Eye wash and drenching equipment should be provided near the workplace. When working in places where contact with the product is possible, attention should be paid to personal hygiene and the skin in contact with the product should be washed with washing products before eating, smoking and leaving the workplace.
Stop spills as much as possible while ensuring safety. If a minor spill is found, treat it with sand or other absorbent material and place it in a clean, dry container for subsequent disposal. If a large spill occurs, the spilled material should be collected for subsequent disposal. Avoid entering groundwater or surface water as the material is not readily biodegradable. All collected spilled material should be disposed of in accordance with local environmental regulations.
