Light yellow transparent liquid. Soluble in most organic solvents, but insoluble in water

A highly efficient organic tin esterification catalyst. It is widely used in the synthesis and production of saturated resins for powder coatings and coil coatings. It is widely used in the production of aromatic polyol products of flexible polyurethane foam and rigid foam.


Keep dry during storage, and the temperature should be above 10℃. Crystals will be precipitated below 10°C and will not affect the use effect after heating and melting.


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 is suitable to be stored in glass containers, plastic containers, and metal utensils resistant to corrosion by chlorine, and kept tightly sealed. 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.
