Method of Preparation:

There are various synthetic routes for N,N-dimethylcyclohexylamine, depending on the type of raw material there are cyclohexanone method, N,N-dimethylcyclohexylamine method, cyclohexylamine method, phenol method.


The main use of N,N-dimethylcyclohexylamine is as a catalyst for rigid polyurethane foam, which is a low-viscosity, moderately active amine catalyst used in refrigerators, panels, spraying, and on-site infusion of polyurethane rigid foam. The catalyst catalyzes both gel and foam, providing a more balanced catalytic performance for the foam and gel reactions of rigid foams, it is a stronger catalyst for the reaction between water and isocyanate (foam reaction), and it also has moderate catalytic properties for the reaction of polyol plume isocyanate, and it is a strong initial catalyst for the foam reaction. It is a strong initial catalyst for the foam reaction. In addition to hard foam, it can also be used as an auxiliary foaming agent for molded soft foam and semi-hard foam. It has stable and adjustable performance in combination materials and can be stored for a long time.

Storage and transportation:

It should be sealed and stored in dry, cool and ventilated warehouse


200KG/drum Storage: it is recommended to store in dry and cool area with proper ventilation. Please fasten the package cover as soon as possible after the original packaging to prevent the mixing of other substances such as moisture and other substances that may affect the performance of the product.
