Usage

DBTU is an ullra-accelerator for mercaptan-modified CR(1-3phr). It has a vulcanizalion behaviour similar to that of ETU and DETU. It is also used as a seconda accelerator for NR and synthetic rubbers. It disperses easily in rubber. It is non-staining and does not bloom. It is practically odourless Antioxidant for NR, antiozonant for NR and SR, particularly SBR. It is also a corrosion inhibitor.
