What is methyl ethyl ketone peroxide used for?

Methyl Ethyl Ketone Peroxide is a colorless to yellow liquid with a fragrant, mint-like odor. It is used in making plastic monomers, as a curing agent in polyester resins, and as a cross-linking agent and catalyst in making polymers.

Is methyl ethyl ketone peroxide toxic?

Methyl Ethyl Ketone Peroxide (MEKP) is a highly toxic clear liquid used as a solvent. It is a strong oxidizing agent and a corrosive. Acute and chronic toxicity can occur as an occupational hazard.

How do you dispose of methyl ethyl ketone peroxide?

Disposal of Methyl Ethyl Ketone Peroxide (MEKP) : 1. Harden with polyester resin, and dispose in landfill.

What is MEKP catalyst?

MEKP (Methyl Ethyl Ketone Peroxide) is a catalyst used in the composites industry for polyester and vinyl ester resins and gel coats. It reacts with the resin to turn it from a liquid to a solid (cure it). It is used in varying ratios, generally between 1%-3%, depending on the product being used.

How do you make methyl ethyl ketone peroxide?

The invention provides a kind of method that use acid-exchange resin makees catalyst preparation methyl ethyl ketone peroxide, it is using butanone and hydrogen peroxide as raw material, catalyst is made with acid-exchange resin, using dibutyl phthalate as diluent, after constant temperature stirring reaction, standing …

Does MEKP have a shelf life?

This MEKP is the catalyst/hardening agent for polyester resins and polyester gelcoats. This item has a shelf life of approximately 2-3 months. One gallon will cure approximately 100 gallons of resin and 50 gallons of gelcoat.

What is keto methyl group?

A methyl ketone is a ketone in the molecule of which one ligand on the carbonyl carbon is a methyl group.

Is methyl ethyl ketone a hazardous waste?

Methyl Ethyl Ketone is a colorless liquid with a fragrant, mint-like odor. It is used as a solvent and in making plastics, textiles, and paints. * Methyl Ethyl Ketone is on the Hazardous Substance List because it is regulated by OSHA and cited by ACGIH, DOT, NIOSH, DEP, HHAG, NFPA and EPA.

Does Mekp go bad?

Indeed, Mekp goes bad under influence of sunlight. Try and store it in a closed container, in the dark. If the polyester resin is still what it should look like, it usually is still OK, but do some testing beforehand.

How much is MEKP catalyst?

MEKP (Methyl Ethyl Ketone Peroxide) is the catalyst added to polyester resins and vinyl ester resins. As the catalyst mixes with the resin, a chemical reaction occurs, creating heat which cures (hardens) the resin. Use approximately 1/2 oz per quart of resin.

What is the pH of MEKP?

MEKP is a strong oxidizing agent. MEKP is hydrolytically stable over a range of environmentally relevant pH and temperature conditions (half-lives of 204, 1155, and 224 hours at 25°C and pH 4.0, 7.0 and 9.0, respectively) following OECD TG 111.
