Technical Data Sheet



DC PC-8 is a tertiary amine

used primarily to promote the urethane (polyol-isocyanate) reaction in a wide range of rigid foam applications.


DC PC-8 is recommended for

evaluation in a broad range of rigid foams.

A major application is insulation foams, including spray, slabstock, board laminate and refrigeration formulations.  DC PC-8 is also used in rigid foam furniture frame and decorative parts manufacturing.

It can be batched with the polyol or metered as a separate stream.

Storage Information

Qiguang Group recommends that our catalysts be stored in a dry and cool area under appropriate ventilation conditions. Each container should be closed tightly to avoid contamination with moisture or other negative influences that could change the products’ performance in the end use. The optimum storage temperature is between 10 °C and 30° C. Lower and higher storage temperatures are not preferable and should be avoided.

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

Special and use
The main use of N,N-dimethylcyclohexylamine is as a catalyst for rigid polyurethane foams. It is a low viscosity, medium active amine catalyst used in refrigerators, sheets, sprays, and in-situ filled polyurethane rigid foams. The catalyst catalyzes both gelation and foaming, provides a relatively balanced catalytic performance for the foaming reaction and gel reaction of the rigid foam, and has a stronger catalyst for the reaction of water and isocyanate (foaming reaction), and The reaction of the polyol plume isocyanate is also moderately catalytic and is a strong initial catalyst for the foaming reaction. In addition to being used for hard foams, it can also be used to mold auxiliary foaming agents such as soft foams and semi-rigid foams. It has stable performance in the composition, great adjustability and long-term storage.
