What is MEKP hardener?

What is MEKP hardener?

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 dangerous is MEKP?

MEKP is a potentially lethal industrial chemical. Acute poisoning can occur due to accidental or intentional ingestion. Ingestion can affect multiple organ systems, leading to short and long term morbidity.

What is MEKP used for?

Background. Methyl Ethyl Ketone Peroxide (MEKP) is used as a hardener in manufacture of resins, synthetic rubber and other petrochemical plastics. It is an ingredient of paints, varnishes and paint removers. MEKP is also used in fiberglass and plastics industry as a curing agent.

Does MEKP have a shelf life?

Description. This MEKP is the catalyst/hardening agent for polyester resins and polyester gelcoats. This item has a shelf life of approximately 2-3 months.

Is MEKP flammable?

Methyl Ethyl Ketone Peroxide is a COMBUSTIBLE and REACTIVE LIQUID that may burn slowly at first, and after heating can burn violently and explosively.

Is MEKP a VOC?

MEKP is a highly reactive, colorless liquid organic oxidizer, with a pungent burning odor, which has the following properties: Therefore, the normal usage of MEKP at reinforced plastics facilities will not result in any measurable VOC or HAP emissions whatsoever.

At what concentration is acetone hazardous?

Irritant effects have been reported at concentrations of 500 ppm (1210 mg/m3) and higher. Transient effects were reported in workers exposed to 600-2150 ppm (1452-5203 mg/m) (EPA, 1995). Extremely high concentrations (> 29 g/m3) can cause dizziness, confusion, unsteadiness, and unconsciousness (ATSDR, 1994).

Is MEKP catalyst a hardener?

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.
