CHARACTERISTICS of 2,2'-DITHIODIETHYLAMMONIUM-BIS-DIBENZYLDITHIOCARBAMATE (SAA-30):
2,2'-dithiodiethylammonium-bis-dibenzyldithiocarbamate (SAA-30) is classified as an ultra-fast accelerator that produces very rapid sulfur vulcanization while maintaining excellent curing efficiency.
Unlike thiuram accelerators, 2,2'-dithiodiethylammonium-bis-dibenzyldithiocarbamate (SAA-30) does not function as a sulfur donor because it contains no sulfur available for direct cross-link formation.

Instead, 2,2'-dithiodiethylammonium-bis-dibenzyldithiocarbamate (SAA-30) accelerates sulfur crosslinking reactions extremely efficiently when used with elemental sulfur.
One of its most significant characteristics is 2,2'-dithiodiethylammonium-bis-dibenzyldithiocarbamate (SAA-30)'s ability to replace conventional thiurams or dithiocarbamates on an approximately weight-for-weight basis while reducing concerns associated with N-nitrosamine generation.
