MXC-54 Polyurethane Delayed Gel Catalyst

MXC-54 is a high-performance, acid-blocked tertiary amine catalyst designed specifically for polyurethane applications requiring delayed initiation. By balancing the reaction speed, it significantly improves the flowability and structural integrity of both flexible and rigid foams.

Product Overview

• Alias: 2-ethylhexanoic acid solution of triethylenediamine, Amine Catalyst MXC-54, Polyurethane Delayed Gel Catalyst, Acid-closed Tertiary Amine Catalyst.

• Appearance: Light yellow/Amber transparent liquid at room temperature.

• Core Function: Primarily promotes the urethane (polyol-isocyanate) reaction with a distinct delayed-action feature.

Typical Physical Properties

We provide consistent chemical parameters to ensure your production stability:

Key Features & Advantages

• Superior Flowability: Extends the cream time (emulsion time), allowing the liquid to fill complex molds completely before the gel reaction begins.

• Enhanced Curing: Improves the final cure of the foam without the need to prolong demolding times, increasing overall productivity.

• Reduced Corrosivity: Compared to standard polyurethane delay catalysts, MXC-54 offers a lower corrosive profile for equipment longevity.

• Processing Efficiency: Optimizes the balance between mold filling and rapid cycle times.

Suggested Applications

MXC-54 is highly versatile across various polyurethane manufacturing sectors:

• Molded Foam: Ideal for applications requiring precise mold filling and closure (e.g., automotive seating, furniture).

• Rigid Foam & Insulation: Used in polyurethane insulation boards, pipe insulation, and sandwich panels.

• Co-Catalyst Use: Can replace up to 25% of existing catalyst mixes to fine-tune curing without altering initial reaction profiles.

• Specialty Coatings: Suitable for polyurethane sealants and waterproof coating formulations.

Storage, Packing & Safety

Storage Recommendation: > Keep in a dry, cool, and well-ventilated area (Optimum: 10°C – 30°C). Ensure containers are tightly sealed immediately after use to prevent moisture contamination and contact with oxides.

• Shelf Life: 24 months (unopened).

• Standard Packing: 200kg/drum or 180kg/drum (customizable).

• Safety Handling: Avoid inhalation of dust/vapors. Prevent contact with skin and mucous membranes. Maintain good hygiene—wash thoroughly after handling and store contaminated clothing separately.
