Clarified viscous liquid

As a high-efficiency catalyst in the manufacture of polyurethane foam, coatings, adhesives and sealants. It is used as a hardening catalyst for bipartite polyurethane, polyester, nitrocellulose paint, ink and other coatings and warm-air hardening coatings, with good oxidation resistance; used for the production of polyurethane plastics, polyurethane coatings, silicone rubber catalysts, driers, etc. use.

Storage method:

Normal temperature, dark, ventilated and dry place, sealed and stored

Storage and transportation:

Store in an airtight container in a cool, dry place. The storage place must be locked, and the key must be handed over to the technical experts and their assistants for safekeeping. The storage place must be far away from oxidants and water sources.

General-purpose plastic and plastic-sprayed iron drums or glass containers are packaged and transported in accordance with general chemical management regulations.


Packaging: It should be packed in glass containers, plastic containers, and metal utensils resistant to chlorine corrosion, and sealed and stored. Store in a cool, dry place, keep the container tightly closed, and avoid contact with oxides. Do not inhale dust and avoid contact with skin and mucous membranes. Smoking, eating and drinking are prohibited in the workplace. After work, take a shower and change clothes. Store contaminated clothes separately and use them after washing.
