Application of P-Toluenesulfonyl isocyanate (PTSI)
1) P-Toluenesulfonyl isocyanate (PTSI) 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 P-Toluenesulfonyl isocyanate (PTSI) in producing polyurethane coating, system loss caused by wet surface light, yellowing and reaction phenomenon such as foam were reduced.
