how to remove staining antiozonat from sbr gaskets?
(OP)
i used a ppd antiozonant in sbr gaskets, but when the gasket it is installed on pvc pipe, this stain the surface. now i try to remove or blck the migration of the ppd to the gasket surface, any sugestion or method for this?
the best way that I find is put the gaskets in a oven at 150°C for 20 minutes and aply a talc.

The problem it is how to clean the gaskets that we made whith the PPD, I try alcohol, soap, hot water, oven, acid and alcali solutions and any posible combination. The gaskets are clean but in a few days (5 more o less) the antiozonant migrate to the surface again.
Thanks again GrahamBenett and I'm open to any idea.

i hope it will help because by this way quantity of the migrating/exessive /PPD will be reduced
