  • Product Description

  • Seller Information

  • Description

    p-Toluenesulfonyl Isocyanate(PTSI)  is a highly reactive monoisocyanate widely used as a dehydrating agent for solvents, fillers, pigments, and asphalt tar applications. It is also used as a dehumidifier in solvent-based PU coatings, sealants, and adhesives, and in pharmaceutical synthesis intermediates.

    In PU coating/paint applications, PTSI prevents undesirable premature reactions and acts as a stabilizer for moisture-curing materials, preventing deterioration during storage.
