Product Description

1,3,5-Tris[3-(dimethylamino)propyl]hexahydro-1,3,5-triazine is a tertiary amine compound, typically appearing as a colorless to pale yellow viscous liquid with a characteristic amine odor. It is well-known in the industry under various trade names such as Polycat 41, Jeffcat TR-90, and Lupragen N700. This chemical is primarily utilized as a highly effective trimerization catalyst in the production of polyurethane (PUR) and polyisocyanurate (PIR) foams. It promotes the cyclotrimerization of isocyanates, leading to the formation of isocyanurate rings, which enhance the thermal stability and flame retardancy of the final foam products.

Product Usage

1,3,5-Tris[3-(dimethylamino)propyl]hexahydro-1,3,5-triazine is predominantly used as a catalyst in the polyurethane industry. Its primary application is as a trimerization catalyst for the manufacture of rigid polyurethane (PUR) and polyisocyanurate (PIR) foams. These foams are widely used for insulation in construction (panels, spray foam), appliances (refrigerators, freezers), and other industrial applications. The catalyst helps to improve the curing process, dimensional stability, and thermal properties of the foams. It is also found in applications for microcellular polyurethane elastomers and some flexible foam systems where enhanced cure and specific properties are desired.
