Luna-PTSI P

Technical Datasheet | Supplied by DKSH
Luna-PTSI P is a low viscosity reactive additive used for the formulation of polyurethane products supplied by DKSH. It prevents moisture relaced problems by relacing 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. Luna-PTSI P 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 one year. This product is available in Europe, Asia and North America.
