Highly efficient delayed-action accelerator for sulfur-cured natural and synthetic rubber compounds.
Excellent scorch safety with extended processing window at elevated temperatures.
Delivers balanced vulcanization kinetics—fast cure onset after induction period without premature crosslinking.
Compatible with conventional sulfur, CBS, and TBBS accelerator systems for synergistic performance.
Low volatility and good storage stability under standard warehouse conditions.
Tire tread and sidewall compounds requiring precise cure control and heat resistance.
Industrial rubber goods including conveyor belts, hoses, and vibration-damping components.
Automotive non-tire parts such as engine mounts, bushings, and sealing profiles.
Technical rubber products demanding consistent batch-to-batch vulcanization behavior.
Retread cushion gum formulations where extended green strength and controlled cure onset are critical.
