Applications: CDD is a fast curing accelerator for styrene-butadiene rubber, butyl rubber and 4-polybutadiene rubber. In generally,it is unsuitable to natural rubber. CDD is easy incipient scorch, generally adding kinds of thiazole and sulfonamide to improve its safety. CDD mainly used at carbon, industrial products ect.. CDD can be used as main accelerator in styrene-butadiene rubber at level of 0.2-0.75 phr in combinations with 1.5-0.2 phr of sulfonamide and 2.0-0.5 phr of sulfur. CDD can be used as second accelerator at level of 0.05-0.2 phr in combinations with 0.5-2.0 phr of sulfonamide and 2.5-1.5 phr of sulfur. CDD can be used as main accelerator in butyl rubber at the level of 1.0-2.0 phr in combination with 0.5-2.0 phr of sulfonamide and 2.0-1.0 phr of sulfur. CDD is regulated for use in articles in contract with food as specified under BgVV XXI,Category 4 .
Storage: Store closed containers in a cool, dry, well-ventilated area. Avoid exposure to direct sunlight.
Packing: In 25 kg paper bags with plastic inner.
