| Retarder SAFE |
 |
A non-staining and non-discoloring retarder for natural and synthetic rubber compounds.
Use from 0.10 to 2.0 parts per 100 rhc, depending on polymer and accelerator system used.
Very effective with thiazoles, sulfenamides, and dithiocarbamates.
Not effective in low sulfur thiuram cures. Also useful for replasticizing of slightly scorched stocks by cold mill mixing.
Does not bloom at recommended amounts and no odor occurs from the use of Retarder SAFE.
Does not significantly change the fully cured characteristics of the compound. |
