Hegrecat DMCHA (N,N-Dimethylcyclohexylamine, CAS code: 98 - 94 - 2)

Hegrecat DMCHA (N,N-Dimethylcyclohexylamine, CAS code: 98 - 94 - 2)


Appearance: Clear colorless to pale yellow liquid.

Key Properties:

DMCHA is soluble in alcohol and ether solvents, but insoluble in water. As a catalyst, it offers several performance advantages. It is a low - viscosity and medium - active amine catalyst, which can effectively accelerate reactions. In polyurethane synthesis, it plays a key role in both the urethane (polyol - isocyanate) and blowing (isocyanate - water) reactions. Its nitrogen atom's lone pair of electrons can activate the polyol by abstracting a proton from the hydroxyl group, and also coordinate with the isocyanate group, promoting the formation of the urethane linkage. For the blowing reaction, it facilitates carbamic acid formation and decomposition, generating carbon dioxide for foam creation.

Applications:

Rigid Polyurethane Foams:DMCHA is extensively used in the production of rigid polyurethane foams. In insulation boards and panels for buildings, refrigerators, and other appliances, it helps form a fine and closed - cell structure. This structure minimizes heat transfer, enhancing the foam's thermal insulation properties. In spray foam insulation applications, the rapid reaction times it promotes are crucial for achieving a uniform and consistent foam layer. For structural foam used in sandwich panels and composite materials, DMCHA helps control the foam's density and mechanical properties, ensuring it can bear required loads.​

 

Flexible and Semi - rigid Foams:Besides rigid foams, it can also be used as an auxiliary foaming agent in the production of flexible and semi - rigid foams. It contributes to the stability and performance of these foam products, such as in furniture upholstery and automotive interior components.​

 

Polyurethane Coatings and Adhesives: In the manufacturing of polyurethane coatings and adhesives, DMCHA accelerates the curing process. This not only improves production efficiency but also enhances the adhesion strength, hardness, and chemical resistance of the final products, making them suitable for a wide range of applications, from protecting metal surfaces to bonding various materials in the woodworking and packaging industries.​

 

Our DMCHA product is of high purity, ensuring stable and reliable catalytic performance. It undergoes strict quality control to meet the diverse needs of customers in the polyurethane manufacturing field, helping them produce high - quality polyurethane products with excellent performance.
