Accelerator DCBS / N N-Dicyclohexyl-2-benzothiazolsulfene Amide CAS 4979-32-2

1. Acts Accelerator DCBS as a delayed - action primary accelerator for NR, SBR, BR, NBR and synthetic isoprene rubber, ideal for thick - section rubber products like radial tire treads and conveyor belts.
2. Used N N-Dicyclohexyl-2-benzothiazolsulfene amide in rubber compounds bonded to brass - coated steel wires for tire plies and hoses due to its excellent scorch resistance.
3. Functions Accelerator DCBS as a co - accelerator with thiazoles to adjust curing speed for rubber mountings and shock absorbers subject to high dynamic stress.
4. Applied in compression/transfer molding processes requiring long flow times for intricate rubber parts such as sealing rings and gaskets.

1. Store Accelerator DCBS in sealed fiber drums at 15–25℃ in a cool, dry, well - ventilated area to avoid caking and quality degradation.
2. Keep N N-Dicyclohexyl-2-benzothiazolsulfene amide away from direct sunlight, high temperatures (over 35℃) and open flames; avoid contact with strong oxidants and acids.
3. Wear nitrile gloves, chemical safety goggles and a dust respirator during handling to prevent skin/eye irritation and dust inhalation.
4. Do not stack beyond 2 pallets high; separate from food, feed and incompatible substances like strong reducing agents.

1. Offers Accelerator DCBS exceptional scorch resistance, minimizing premature vulcanization risk and enhancing processing safety for rubber compounds.
2. Produces N N-Dicyclohexyl-2-benzothiazolsulfene amide vulcanizates with excellent dynamic performance, suitable for rubber products under repeated stress and load.
3. Compatible Accelerator DCBS with most rubber types and reinforcing fillers, ensuring stable curing and consistent mechanical properties.
4. Low volatility reduces fume generation during processing, improving workshop environment and worker comfort.

DCBS Accelerator DCBS is a skin and eye irritant (H315, H319); prolonged contact may cause dryness and redness. It is not a UN - listed dangerous good for transportation. N N-Dicyclohexyl-2-benzothiazolsulfene amide is harmful to aquatic organisms (H412), so prevent leakage into water bodies. Avoid generating dust during handling to reduce respiratory irritation risks.
