P-Toluenesulfonyl isocyanate (PTSI) (CAS 4083-64-1) is clear, colorless liquid, insoluble in water.
P-Toluenesulfonyl isocyanate (PTSI) can be used as solvent, and filler, pigments such as dehydrating agent and effectively applied to the wet curing one-component and conventional two-component polyurethane coating system. In addition, P-Toluenesulfonyl isocyanate (PTSI) can also be used as a stabilizer and butyl purification of double isocyanate to prevent its deterioration or discoloration.

P-Toluenesulfonyl isocyanate (PTSI) has high reactivity, thus the application and operation should be especially careful. Para-Toluenesulfonyl isocyanate (PTSI) 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.
