PU Foam Triazine catalyst PC 41 Catalyst

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.

Product Benefits

Precise Reaction Control

The PC 41 catalyst delivers a calculated, moderate activity level, granting operators precise command over the polyurethane foaming process. It exhibits outstanding foaming and gel balance capabilities, which are particularly crucial during complex manufacturing runs. In polyisocyanurate (PIR) reactions, this chemical demonstrates highly efficient trimerization selectivity. This specific catalytic action significantly enhances the cross-linking density of the resulting foam matrices, leading to profound improvements in the mechanical strength and load-bearing capacity of structural panels.

Broad Formulation Adaptability

Formulated for maximum versatility, this trimer catalyst is exceptionally soluble in water, making it a prime candidate for fully water-blown foaming systems. It maintains superior compatibility across various rigid and flexible polyurethane foams, as well as complex polyisocyanate blends (with or without foam). Industry guidelines recommend deploying it as a co-catalyst for formulations where the isocyanate index exceeds 105-110. It interacts predictably with other polyurethane catalysts, optimizing reaction kinetics without causing phase separation or unwanted precipitation in the resin blend.

Enhanced Product Stability

By meticulously regulating the exothermic foaming reaction, PC 41 drastically improves the thermal stability and chemical resistance of the final manufactured foam products. This ensures the materials can withstand prolonged exposure to harsh environmental conditions, thereby extending their functional service life in diverse applications. Furthermore, the liquid formulation possesses low volatility characteristics, which minimizes active component loss during high-temperature processing and reduces residual amine emissions in the finished goods.

Package:

It is packed in 180 kg/drum. The industrial-grade steel drums are specifically selected to prevent contamination, resist physical impact, and maintain absolute chemical integrity during long-distance transit and extended warehousing periods.

Storage:

Please store in a cool, ventilated place. Strict adherence to moisture-proof and anti-oxidation protocols is required. Keep all containers tightly sealed when not in active use to prevent atmospheric moisture absorption, which could otherwise compromise the catalyst's reactivity.

Usage

This catalyst is applied to various rigid polyurethanes and polyisocyanates with and without foam. It is recommended to be used as a co-catalyst with other polyurethane and polyisocyanate catalysts, especially in formulations where the isocyanate index is greater than 105-110. The exceptional solubility and controlled reactivity make it suitable for multiple advanced manufacturing techniques.

FAQ

Q1: What is the recommended dosage of PC 41 catalyst?

A1: The optimal dosage heavily depends on the specific formulation parameters, typically ranging from 0.1% to 1.0% of the total resin weight. For specialized formulations featuring a high isocyanate index (>105-110), we strongly recommend initiating trials with a baseline of 0.3-0.5%. Operators should then carefully adjust the concentration based on observed foaming speeds, gel times, and final curing performance.

Q2: Is PC 41 compatible with water-based polyurethane systems?

A2: Yes, it is highly compatible with both water-based and solvent-based polyurethane systems due to its excellent water solubility. It performs exceptionally well in fully water-blown PIR formulations. However, we always advise conducting preliminary compatibility and reactivity tests with your specific chemical blends to ensure optimal results, as varying water content levels can directly influence the overall catalyst activity and reaction profile.

Q3: What safety precautions should be taken when handling PC 41?

A3: Facility operators must wear appropriate personal protective equipment (PPE), including chemical-resistant gloves, protective goggles, and full-coverage clothing to prevent any direct contact with skin and eyes. The storage area must be kept well-ventilated, strictly away from strong oxidizing agents and direct heat sources. In the event of accidental exposure, immediately rinse the affected area thoroughly with copious amounts of water and seek professional medical attention if any irritation persists.
