Cure-Rite® 18 (OTOS) is an efficient, thiocarbamyl sulfenamide rubber accelerator producing short cross-links. The derived vulcanizates improve the compression set, reversion resistance, and oxidative stability of the rubber goods. Additional advantages of Cure-Rite® 18 are obtained due to low heat build-up and low compression set in the field. Formulators will find technical and economic synergy when Cure-Rite 18 is used with Cure-Rite BBTS or Cure-Rite OBTS to vary length of crosslinks and vulcanizate properties.
Cure-Rite 18 is used in rubber applications such as natural rubber (NR) compounds—including off-the-road tires or engine mounts—as well as styrene-butadiene rubber (SBR) tread compounds, butadiene rubber (BR) tread compounds, and vibration dampening rubber.
Cure-Rite 18 is offered in powder and pellets and is also available in a proprietary, non-dusting powder form for excellent dispersability, Cure-Rite18/80.
