There are many synthetic routes for N,N-dimethylcyclohexylamine. According to different types of raw materials, there are cycloethanone method, N,N-dimethylcyclohexylamine method, cyclohexylamine method, and phenol method.
The main use of N,N-dimethylcyclohexylamine is as a catalyst for rigid polyurethane foam. It is a low-viscosity, moderately active amine catalyst used for refrigerators, plates, spraying, and in-situ polyurethane foam infusion. The catalyst has a catalytic effect on both gel and foam, and provides a more balanced catalytic performance for the foaming reaction and gel reaction of hard foam. It has a stronger catalyst for the reaction of water and isocyanate (foaming reaction). The reaction of polyol feather isocyanate is also moderately catalytic, and it is a strong initial catalyst for the foam reaction. In addition to hard foams, it can also be used as an auxiliary foaming agent for molding soft foams and semi-rigid foams. It has stable performance, great adjustability, and long-term storage.
Storage and transportation:
Should be sealed and stored in a dry, cool and ventilated warehouse
200KG/drum Storage: It is recommended to store in a dry and cool area with proper ventilation. After the original packaging, please fasten the packaging cover as soon as possible to prevent the water and other substances from mixing into the product and affecting its performance.
