Methyl ethyl ketone peroxide, or MEKP, is an agent that cures resins and gel coats that are used in fiberglass swimming pools. The pool’s gel coat is applied as a liquid using spray painting equipment.
MEKP is used in a 1-3% solution to act as a hardening agent, turning the “paint” of a gel coat into a solid and durable top layer of a fiberglass pool.
Methyl ethyl ketone peroxide is an organic compound, and it’s highly caustic. It’s a severe skin irritant, and prolonged exposure can cause blindness or corrosive damage. Manufacturers take extreme care when using MEKP as a catalyst for the gel coat.
