Properties:White powder (granule). The density is 1.29. Soluble in benzene, acetone, chloroform, CS2 partly soluble in alcohol, diethyl ether, CCI4 insoluble in water, gasoline and alkali with lower concentration. Meeting hot water becomes to dimethyl ammonium and CS2. Be sensitive to skin and peogaster.
Application:Can
be used as a single accelerator, as a secondary accelerator or as
a sulphur donor in most sulphur-cured elastomers. Scorchy and
gives fast cure rates. Produces an excellent vulcanisation
plateau with good heat aging and compression set resistance in
sulphurless and EV cure systems Good color retention is obtained
in non-black vulcanisation.
A valuable secondary
accelerator for EPDM. May be used as a retarder in the
vulcanisation of chloroprene rubber.
