Product Description

Product Description

Applications:

1. Polyurethane Foaming Catalyst: Used in the production of flexible foams (such as sofas, mattresses, and car seats) and rigid foams (such as building insulation boards and refrigerator cold chains) to precisely control the foaming and gelation reaction rates, optimize cell structure, and improve the mechanical strength, dimensional stability, and aging resistance of the products.

2. Epoxy Resin Curing Accelerator: Accelerates the curing reaction of epoxy resins, increases crosslinking density, and is suitable for electronic packaging, composite materials, etc.

3. Electroplating Additive: As an alkaline zinc plating brightener, leveling agent, and refining agent, it condenses with dichloroethyl ether to form diaminourea polymer (PUB), resulting in a uniform and dense coating.

4. Flotation Collector: Used in mining for the flotation separation of sulfide ores (such as chalcopyrite and sphalerite), exhibiting high selectivity.

5. New Energy Materials
Used in emerging fields such as polyimide catalysts and water-blown flexible polyurethane foam active systems.

Core Advantages:
Highly Efficient Catalytic Performance
The bis-tertiary amine structure endows it with strong alkalinity and high reactivity, significantly shortening curing time and improving production efficiency.

Excellent Process Compatibility
Good compatibility with polyols, isocyanates, and other systems; wide operating window, suitable for continuous industrial production.

Environmentally Friendly and Free of Heavy Metals
Contains no heavy metal components, in line with the trend of green chemistry.

Improved Product Performance
Promotes uniform cell formation, enhances resilience, support, and long-term durability; reduces thermal conductivity in rigid foam, improving insulation performance.

High Purity and Stability
