use for tyre making nitrosamine-free accelerators
nitrosamines solutions to the nitrosamine issue
Due to its very scorchy nature, this accelerator has a very limited but important use in the rubber formulations. Typically, ZIX is used in very low or room temperature cure systems for adhesive cements, tank linings, coatings, patching compounds, etc. Robac® AS-100 is a new alternative, primary accelerator used globally in dry elastomers and
