Properties: It is white powder with ammonia smell which melts in water other than non-polar solvent.

Application: It is served as vulcanizing agent in FKM. Comparing with HMDC, Diak no.2 also produces air hole but acts much safer, especially in high-viscosity FKM. 2 portion Double oil salicylic propyl diamine can be added to replace a small portion of Diak no.2 if it’s too fast. 0.85 -1.25 portions is recommended in carbon black rubber and 1.25-1.85 in mineral filling rubber.

Storage:It is stable for 2 years sealed in room temperature. It is non-toxic, but protective equipment should be wore in case of eye contact and inhalation. Wash thoroughly after contact. Do not swallow. 

Package: 5±0.1kgs/ carton, 25±0.2kgs/fiber drum, or by your requirements.
