Cobalt Octoate (12% Co, High Strength)

Cobalt Octoate at 12% cobalt content is a high-concentration MEKP accelerator for situations where lower dosing volumes are preferred or where resin formulation requires a compact cobalt source. By using a 12% cobalt solution instead of the standard 6%, the volume required is halved while delivering equivalent cobalt activity. This is advantageous in automated metering systems where precise small-volume dosing is more reliable, in highly filled resin systems (SMC, BMC) where space for additives is limited, and in spray equipment where a concentrated accelerator reduces the number of metering pump strokes needed. The chemistry, handling requirements, and safety profile are identical to 6% cobalt octoate — the product is simply a more concentrated solution in the same hydrocarbon carrier. Typical usage is 0.1–0.3% by weight of resin (equivalent to 0.2–0.6% of the 6% grade). As with all cobalt accelerators, it must never be mixed directly with MEKP or other peroxides. Under REACH, cobalt octoate including this grade is subject to regulatory restrictions as a reproductive toxin. Users should evaluate cobalt-free alternatives as part of their REACH compliance strategy.
