Overview:

Niax Catalyst B-4 tertiary amine catalyst;

 

Niax Catalyst B-4 is a liquid, low odor, water soluble tertiary amine available in compositions for the production of flexible polyether based polyols. Niax catalytically active catalysts B-4 can be added as separate streams or mixed with water, polyols, etc. for metering into the foam of the mixing chamber machine Niax catalysts B-4 are intermediates at high activity between active materials, such as Niax catalyst A-1, and moderately active catalysts, such as Niax catalyst A-33.

Niax catalyst B-4 provides excellent gelation between the equilibrium and blowing reactions.

In this report Niax catalyst B-4 functions excellently as the only amine wide catalyst for flexible foam formulations.

The data provided in this report show the performance of a typical feature of a slabstock flexible polyurethane foam formulation containing Niax Catalyst B-4.

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.

 

Shelf life

Under proper storage conditions, the shelf life is 6 months from the date of manufacture, after which the product can be used after retesting.

 

Safety Information

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.

 

Leak handling

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.
