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

An efficient organotin esterification catalyst. It is widely used in the synthetic 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.


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


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

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


Packaging: It is advisable to use glass containers, plastic containers, and metal utensils that are resistant to chlorine corrosion, and store them in an airtight container. Store in a cool, dry place and keep container tightly closed to avoid contact with oxides. Do not breathe dust and avoid contact with skin and mucous membranes.
