Description
P-Toluenesulfonyl Isocyanate PTSI is a mono-isocyanate with high reactivity, widely employed as a dehydrating agent in chemical products, including solvents, fillers, pigments, and pitch tar applications. It also functions as a moisture scavenger for solvent-based PU coatings, sealants, adhesives, and serves as a chemical intermediate. In PU coating/paint applications, HARTTIVE MSI can prevent undesirable premature reactions and act as a stabilizer for moisture-curing materials, preventing deterioration or discoloration during storage.
