Luna-PTSI P

Luna-PTSI P distributed by DKSH is a low viscosity reactive additive used for the formulation of polyurethane products. It prevents moisture related problems by reacting with trace moisture. Excess water reacts with Luna PTSI-P towards the corresponding carbamic acid, which undergoes immediate decomposition to form carbon dioxide and the relatively inert p-toluenesulfonamide, which is commonly used as a plasticizer.

• It prevents thickening of polyurethane coatings during storage.
• It does not dimerize or trimerize as alkyl and aryl isocyanates do.
• When stored, purified diisocyanates tend to deteriorate and discolor.
• In this case, Luna-PTSI P can be used for stabilization to improve shelf life.
• It has a shelf life of 18 months.
• This product is available in Europe, Asia and North America.
