Product Description: A non-staining and non-discoloring retarder for natural and synthetic rubber compounds. Use from 0.50 to 1.3 parts per 100 phr, depending on polymer and accelerator system used. Very effective with sulfonamide systems. Effective in thiazole systems as well as low sulfur/thiuram cures. Also useful for replasticizing of slightly scorched stocks by cold mill mixing. Replaces Retarder SAFE in many applications at a lower cost. When Retarder RSF is used in natural rubber, reversion is minimized. Does not bloom at recommended amounts and no odor occurs from the use of Retarder RSF. Does not significantly change the fully cured characteristics of the compound. State-of-cure is effected less than with most other retarders.Information provided by Akrochem Corporation |
