In industrial rubber products. CBS can be used with secondary accelerators, like as the TMTD to replace MBTS/DPG systems.
CBS can also be used in EPDM and NBR compounding as the primary accelerator, giving good scorch delay and fast cure rates.
CBS can be (in combination with CTP) used as an alternative for NOBS. it can avoid the problem caused by N-nitrosamines. And it also has the equal function on scorch safety and faster cure rate as NOBS
***Handling and Storage recommendations
Store CBS in single stacked pallets in a cool, dry, well-ventilated area, avoiding exposure of the packaged product to direct sunlight.
Do not store this product near insoluble sulfur as the amine vapors characteristically emitted from this material can cause insoluble sulfur to revert to rubber marker’s sulfur.
Usually the shelf time is 12 months while the recommend use of date is 6 months.
