Catalyst

MEKPO Butanox M-60

Packing 5 kg/gallon, 4 gallon/box

is an organic peroxide, a high explosive similar to acetone peroxide. MEKP is a colorless, oily liquid whereas acetone peroxide is a white powder at STP; MEKP is slightly less sensitive to shock and temperature

Application MEKP are used in industry and by hobbyists as the catalyst which initiates the polymerization of poly ester resins used in glass-reinforced plastic, and casting

Designed to be used with Polyester resins and gelcoats to harden the product. As a medium activity hardener this is our most popular catalyst for GRP and can be added at 1-2% by weight

Precaution MEKP is a severe skin irritant and can cause progressive corrosive damage or blindness

MEKP should never be added to hot solvents or monomers as a violent decomposition and/or reaction may result. When using spray equipment, never spray raw MEKP onto curing or into raw resin or flues. Keep MEKP in its original container

HANDLING AND STORING
Keep containers closed to prevent contamination. Rotate stock using the oldest material first. The activity and stability of MEKP is directly related to the shipping and storage temperature history. Cool storage at 80?F or below is recommended for longer shelf life and stability. Prolonged storage at elevated temperatures of 100?F and higher will cause product degradation, gassing and potential container rupture which can result in a fire and/or explosion.
