Methyl ethyl ketone peroxide (MEKP) is a colorless liquid used primarily as a catalyst in the production of fiberglass and other polymer materials. It is an organic peroxide that helps initiate the curing process of resins, making it essential in industries like construction and automotive. MEKP is highly reactive and can be hazardous if not handled properly. It can cause skin and eye irritation, and its vapors may be harmful if inhaled. Therefore, safety precautions, such as using protective gear and ensuring proper ventilation, are crucial when working with this chemical.
