Import Dmdbh Curing Agent — Buy in Bulk from Supplier in China

DMDBH curing agent is a bifunctional organic peroxide supplied by Credit Group in Beijing, China. The product appears as a transparent, evenly distributed paste with an assay of 43.0‑45.0 % and a CAS number of 78‑63‑7. Its molecular weight is 290.4 g·mol‑1, density at 20 °C is 0.870 g·cm‑3, flash point 56 °C, and freezing point 6 °C. The recommended maximum storage temperature (TS max) is 30 °C and the self‑accelerating decomposition temperature (SADT) is measured at 80 °C. Packaging is supplied in standard 18 kg drums.

The peroxide nature of DMDBH means it is thermally unstable and must be handled under controlled conditions. Typical organic peroxide grades for silicone crosslinking maintain purity between 40‑50 % active oxygen, which aligns with the 11.02 % peroxide content listed for this batch. Under the advised storage temperature, the material retains its specifications for at least six months after delivery, matching industry expectations for shelf life. Standard safety practice for peroxides includes dry, well‑ventilated storage away from heat sources, reducing agents and metals, as highlighted in the supplier’s handling notes.

DMDBH is employed to crosslink silicone rubber, providing excellent scorch safety and allowing processing at 135 °C for a minimum of 20 minutes. Typical cure cycles reach a crosslink temperature of 175 °C with a rheometer t90 of about 12 minutes. Buyers such as silicone component manufacturers usually request bulk quantities in 18 kg drums and will need to confirm minimum order quantities, Incoterms and payment terms directly with Credit Group before placing an order.
