Product Description: Activator STAG is a relatively non-staining, non-discoloring activator for thiazole type accelerators. This surface treated activator requires 1% maximum stearic acid with normal Zinc Oxide and Sulfur for vulcanization. Excess stearic acid results in tensile strength loss. Can be used as an equal concentration replacement for diphenylgnanidine with excellent scorch safety and storage stability. Accelerator STAG, having very good dispersing qualities, is usually a primary accelerator for Natural Rubber. It is a strong secondary accelerator in SBR for the sulfenamides, thiurams, and thiazoles.Information provided by Akrochem Corporation |
