PROPERTIES:
White powder/granule,inodorous.The density is 1.66g/cm3.Soluble in hot chloroform and benzene, insoluble in acetone, carbon tetrachloride, alcohol and water, a little soluble in gasoline, benzene, methyl benzene and hot alcohol.
APPLICATION:
ZDMC is a secondary ultra accelerator for thiazole and sulfenamide cure systems for general purpose polymers (NR, SBR, IIR, EPDM).
It can also be used as a primary accelerator in some continuous cure applicants.
ZDMC is widely used in both natural and synthetic lattices.
As tasteless, no pollution, no discoloration, therefore applicable to the tape, food and pharmaceutical use rubber products. In the United States, ZDMC has been approved by the FDA.
