Trimerization Catalyst PC-41 1,3,5-Tris[3-(dimethylamino)propyl]hexahydro-1,3,5-triazine CAS 15875-13-5 For PU Foam

Product Overview

PC 41 1,3,5-Tris[3-(dimethylamino)propyl]hexahydro-1,3,5-triazine (CAS: 15875-13-5, MF: C18H42N6, MW: 342.58) operates as a moderately active trimer catalyst specifically engineered for demanding polyurethane foam production cycles. Presenting as a colorless to light yellow liquid, it carries a characteristic mild amine scent and flows with a consistent, low viscosity that ensures rapid dispersion during mixing phases. This chemical agent features a melting point of 268-271 °C, a boiling point of 141-142°C, and a density of 0.92, alongside a total amine value of 490-530 mgKOH/g.

As a specialized polyurethane catalyst, it takes on a critical function in regulating the complex foaming reaction, directly influencing uniform cell structure formation and final material performance. PC 41 serves as an exceptionally reliable equivalent to international mainstream models such as Polycat 41, Jeffcat TR-90, and Lupragen N600. By integrating this catalyst, procurement teams and facility managers can significantly reduce operational expenditures without the need to alter existing, validated formulations. It is highly effective in the production of both rigid and flexible polyurethane foams, offering a stable catalytic profile that prevents premature curing while ensuring complete cross-linking.
