production method:

It is made by dehydrochlorination of dimethyltin dichloride and neodecanoic acid.


the effect on the environment:

The US Occupational Safety Administration (OSHA) environmental safety standards for the use of organic tin for all industries [8H TWA (8-hour average) is 0.1mg/m (in tin); short-term exposure is 0.2 mg/m];



Clear 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 bicomponent polyurethane, polyester, nitro paint, ink and other coatings and air-curing coatings. It has good oxidation resistance; it is used as a catalyst and drier for the production of polyurethane plastics, polyurethane coatings, silicone rubber, etc. use.


Storage method:

Normal temperature, avoid light, 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. The place of storage must be far away from oxidant and water source.

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



Packing: It should be packed in glass containers, plastic containers, and metal containers resistant to chlorine corrosion, sealed and stored. Store in a cool, dry place, keep the container sealed and avoid contact with oxides. Do not breathe dust, avoid skin and mucous membrane contact. Smoking, eating and drinking are prohibited in the workplace. After work, shower and change clothes. Store contaminated clothing separately and wash it before reuse. Maintain good hygiene habits.
