PROPERTIES:


TMTM is yellow powder/granule. Density is 1.37-1.40. Soluble in benzene, acetone, CH2Cl2, CS2, toluene, partially soluble in alcohol and diethyl ether. Insoluble in gasoline and water. Stabilization for storage.

APPLICATION:


Generally used as a secondary accelerator or as a booster for sulphenamides to achieve faster cure rate. Distinguished by very good processing safety in comparison with other thiurams high curing activity and no discoloration. No cure activity in the absence of added elemental sulphur.
An excellent accelerator for polychloroperene in association with DPG and sulphur.
Its critical temperature is 121.0℃.
