Important Safety Information

Methyl Ethyl Ketone Peroxide (MEKP)

MEKP is among the more hazardous materials

found in commercial channels. Proper handling

of the “unstable (reactive)” chemicals presents a

and caution in its storage, transportation, handling,

processing and disposal.

:RUNHUVPXVWEHWKRURXJKO\LQIRUPHGRIWKHKD]DUGV

that may result from improper handling of MEKP,

especially in regards to contamination and heat.

They must be thoroughly instructed regarding the

disposal of MEKP and other hazardous materials

used in the laminating operation.

Polyester Resins and Gel-Coats

Spraying and Lamination Operations

GlasCraft recommends that you consult OSHA

Sections 1910.94, 1910.106, 1910.107 and NFPA

No. 33, Chapter 16,17, and NFPA No. 91 for further

guidance.

Spraying materials containing polyester resin and

gel-coats creates potentially harmful mist, vapors and

atomized particulates. Prevent inhalation by providing

Read the material manufacturer’s warnings and ma-

related to polyester resins and gel-coats.

To prevent contact with polyester resins and gel-

coats, appropriate personal protective equipment,

including chemically impermeable gloves, boots,

as well as potentially damaging to the eyes and

skin.

Read material manufacturer’s warnings and

PDWHULDO06'6WRNQRZVSHFL¿FKD]DUGVDQG

precautions related to MEKP.

Contaminated MEKP can become explosive.

Prevent contamination of MEKP with other materi-

als, which includes, but is not limited to polyester

overspray, polymerization accelerators and promot-

ers, and non-stainless metals. Even small amounts

WXUH6$'7ZKLFKFDQFDXVH¿UHRUH[SORVLRQ

Spills should be promptly removed, so no residues

remain. Spillage can heat up to the point of self-

ignition. Dispose in accordance with manufacture’s

recommendation.

Store MEKP in a cool, dry and well-ventilated area

in the original containers away from direct sunlight

and away from other chemicals. It is strongly recom-

mended that the storage temperature remain below

86° F (30° C). Heat will increase the potential for ex-

plosive decomposition. Refer to NFPA 432.
