1,3-bis[3-(dimethylamino)propyl]urea CAS 52338-87-1 Alkaline zinc plating brightener PU

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. Pharmaceutical Intermediate: Used in the synthesis of various pharmaceutical active ingredients and is an important intermediate in the pharmaceutical industry.

5. Flotation Collector: Used in mining for the flotation separation of sulfide ores (such as chalcopyrite and sphalerite), exhibiting high selectivity. 6. New Energy Materials
Used in emerging fields such as polyimide catalysts and water-blown flexible polyurethane foam active systems.
