Kemiitti 810 OP is a chemically sensitised emulsion explosive. The product is manufactured from emulsion matrix at the charging site and pumped through a hose directly into the borehole. In the borehole, the product sensitises into a finished explosive within 10–30 minutes of charging. Ammonium nitrate prills may not be mixed with the K810 OP product during charging.

Kemiitti 810 is suitable for all kinds of applications in open cut mining, especially in those operations that require quick charging and/or good water resistance, while releasing less nitrogen to the environment. The product is grease-like in consistency and white or yellowish in colour. Depending on the capacity of raw material containers, 9 to 27 tonnes of finished explosive can be manufactured on the vehicle at once. Local regulations must be taken into consideration when using Kemiitti 810 OP. The product may only be used with a specific agreement on special sites.
