Signs and Symptoms of Exposure:
INHALATION: Moderately toxic by inhalation.
EYE CONTACT: Eye contact causes severe corrosion and may cause blindness.
SKIN CONTACT: Severe skin irritant, causes redness, blistering and edema.
INGESTION: Human systemic effects by ingestion may include changes in structure or function of esophagus,
nausea or vomiting, and other gastrointestinal effects.
Conditions Generally Aggravated by Exposure: There are no known medical conditions which are recognized
as being aggravated by exposure.
SECTION 4: EMERGENCY AND FIRST AID PROCEDURES
INHALATION: Remove victim to fresh air. If coughing, breathing becomes labored, irritation develops or other
symptoms develop, seek medical attention at once, even if symptoms develop several hours after the exposure.
EYE CONTACT: Remove any contact lenses at once. Immediately flush eyes with large quantities of clean water
for at least 15 minutes. Ensure adequate flushing by separating eyelids with fingers. If irritation or adverse
symptoms develop seek medical attention.
SKIN CONTACT: Immediately flush skin with water for at least 15 minutes while removing contaminated clothing.
Wash contaminated clothing before reuse or discard the contaminated clothing. If irritation or adverse symptoms
develop, seek medical attention.
INGESTION: Do NOT induce vomiting. Drink plenty of water. Immediately call physician. For aid to physician,
suggest local Poison Control Center.
SECTION 5: FIRE AND EXPLOSION HAZARD DATA
Flash Point (Method Used): >200癋 (>93癈) COC
Flammable limits: LEL: Unknown UEL: Unknown
Extinguishing Media: Water from a safe distance ?preferably with a fog nozzle. In case of very small fires, other
means such as carbon dioxide, foam or dry chemical extinguishers may be effective. Dry chemical combined with
Methyl Ethyl Ketone Peroxide formulations may re-ignite. Light water additives may be particularly effective at
extinguishing Methyl Ethyl Ketone Peroxide fires.
Special Firefighting Procedures: Firefighters should be equipped with protective clothing and self-contained
breathing apparatus. In case of fire near storage area, cool the containers with water spray. If dry chemical is used
to extinguish a Methyl Ethyl Ketone Peroxide fire, the extinguished area must be thoroughly wetted down with water
to prevent re-ignition.

DOCUMENT NO.: 14822 805-FRM011
M-Bond 300 Catalyst MSDS # MGM009J
Unusual Fire and Explosion Hazards: The heat of decomposition of the peroxides adds to the heat of the fire.
Dry chemical fire extinguishing agent may catalyze the decomposition.
SECTION 6: ACCIDENTAL RELEASE MEASURES
Steps to be taken if material is released or spilled: Dike spill to prevent runoff from entering drains, sewers,
streams, etc. Wet spilled material with water and absorb with an inert absorbent material such as perlite,
vermiculite, or sand. Sweep up using non-sparking tools and place in a clean polyethylene drum or a polyethylene
pail. DO NOT place into a steel container, lined or unlined, as decomposition may occur. Treat any contaminated
cardboard packaging as hazardous waste. Wet container contents with additional water prior to sealing.
SECTION 7: EXPOSURE CONTROLS -- PERSONAL PROTECTION
Respiratory Protection: If airborne concentrations are expected to exceed acceptable levels wear a
NIOSH/MSHA approved air-purifying respirator with an organic vapor cartridge or canister. When using respirator
refer to OSHA's 29CFR 1910.134.
Ventilation: Mechanical; general.
Protective Gloves: Protective gloves recommended, solvent resistant, such as butyl rubber, nitrile or neoprene
Eye Protection: Safety goggles recommended. Permanent eyewash is highly recommended.
Other Protective Clothing or Equipment: Safety shower and eye wash fountain is recommended when the risk
of a significant exposure exists.
Work / Hygienic Practices: Wash thoroughly after use.
SECTION 8: HANDLING AND STORAGE
Precautions to be taken in handling and storing: Rotate stock using oldest material first. Avoid contact with
skin, eyes and clothing. Keep containers closed to prevent contamination. Keep away from sources of heat,
sparks, or flame. Do not add to hot solvents or monomers as a violent decomposition and/or reaction may result.
When using spray equipment, never spray raw Methyl Ethyl Ketone Peroxide onto curing or into raw resin or flues.
Keep Methyl Ethyl Ketone Peroxide in its original container. Do not use near food or drink. Wash thoroughly after
handling. The stability of Methyl Ethyl Ketone Peroxide formulations is directly related to the shipping and storage
temperature history. Cool storage at 80癋 or below is recommended for longer shelf life and stability. Prolonged
storage at elevated temperatures of 100癋 and higher will cause product degradation, gassing and potential
container rupture which can result in a fire and/or explosion. Store out of direct sunlight in a well ventilated area
away from combustible and incompatible materials.
Other Precautions: Unmixed, uncontaminated material, remaining at the end of the day, shall be returned to a
proper organic peroxide storage area. Under no circumstances should material be returned to original container.
