Application

1) Tosyl Isocyanate can be used in the process of making paint as solvent, filler, pigment and asphalt tar dehydrating agent, such as the react with water to produce carbon dioxide and toluene sulfonamide, the latter is usually not with alkyl isocyanate and aryl isocyanate reaction, and dissolve in ordinary solvents. In addition, it will not lead to system yellowing phenomenon. Through the use of Tosyl Isocyanate in producing polyurethane coating, system loss caused by wet surface light, yellowing and reaction phenomenon such as foam were reduced.
2) In Pharmaceutical industry, it is often used as Pharmaceutical intermediate.

Packing

Storage
Tosyl Isocyanate has high reactivity, thus the application and operation should be especially careful.  Tosyl Isocyanate reacts fast with water, alcohol, amine, acid and alkali, and therefore do not pour into this kind of material in the product containers. Its reaction with 1 gram of water and the carbon dioxide gas is 1.3 liters. Such as moisture into the container, in a very short time a large number of gas will occur, which can cause the container (even closed container) to be on fire.

This product is sensitive to moisture, so it should be in sealed, original packaging container, dry storage. Under good condition, the shelf life is at least six months.
