Tosyl isocyanate

CAS: 4083-64-1
HARTTIVEMSI (PTSI)
Type: Monofunctional isocyanate.
Supply Form: Solvent-free, colorless liquid.
Application: A stabilizer used in transparent and colored moisture-curing liquid PU coatings.
Specification: Active substance content (initial method) (98±2)%
Flash point (DIN51584): 150°C
Density, 20°C (DIN51757): approx. 1.29 g/cm³
Compatibility: Compatibility with paint resins must be tested.
Application: In paint formulations, HARTTIVEMSI (PTSI) reacts with residual moisture in pigments and solvents, producing carbon dioxide and soluble inert compounds. Theoretically, 12 grams of HARTTIVEMSI (PTSI) react with 1 gram of water, but experience shows that using a larger amount is more effective.
Shelf Life: HARTTIVEMSI (PTSI) is moisture-sensitive and must be stored in its original sealed container. If stored properly, HARTTIVEMSI (PTSI) remains stable for at least six months.
