Methyl ethyl ketone peroxide (MEKP) is a high explosive similar to acetone peroxide, and is extremely dangerous to synthesize. Unlike acetone peroxide, however, MEKP is a colorless, oily liquid at room temperature and pressure, while acetone peroxide is a white solid. It is slightly less sensitive to shock and temperature.
Dilute solutions of MEKP are used in industry and by hobbyists as the catalyst which initiates the polymerisation of polyester resins used in glass-reinforced plastic, and casting.
MEKP is a severe skin irritant and can cause progressive corrosive damage or blindness if contacted with the eyes.
