foam or water fog.
SPECIAL FIRE FIGHTING PROCEDURES: The product is not in the flammable range but will burn. Carbon
monoxide may be formed present due to where incomplete combustion. Wear self-contained breathing apparatus
for protection from smoke and fumes.

5 - HAZARD DATA
Hazard Identification: Irritating to the eyes and skin. May cause sensitization by skin contact.
Moderately toxic to fish. Not readily biodegradable. Has a moderate potential to bioaccumulate (log Pow in the
range of 3 to 5). Moderately toxic to aquatic animals; non-toxic to algae; insignificant toxicity to microorganisms.
EPON 828 DLC-A NATROCHEM MSDS PAGE 2 OF 5
CHRONIC HEALTH EFFECTS: An epidemiological study was conducted which included 165 workers who had
been exposed to precipitated silica for an average of 18 years. No adverse effects were noted in complete
medical examination (including chest roentgenograms) of these workers. Pulmonary function decrements were
correlated only with smoking and age but not with the degree or duration of dust exposure. Laboratory studies
have also been conducted in small animals via inhalation to levels of precipitated silica dust of up to 126 mg/m3
for periods from six months to two years. Although precipitated silica was temporarily deposited in the animal's
lungs, most of the deposited material was cleared soon after the dust exposure ended. The results of all studies
performed by, or known to, PPG indicate a very low order of pulmonary activity for synthetic precipitated silica.
ACUTE TOXICITY: Oral LD50 >2000 mg/kg (rat)
Dermal LD50 >2000 mg/kg (rabbit)
Irritation: Eyes: moderate
Skin: moderate
Sensitization: Skin sensitizer in man
Other toxicological effects: In vitro mutagen, but mutagenic potential not see in vivo.
PRIMARY ROUTE OF ENTRY- Inhalation.
CHEMICAL LISTED AS CARCINOGEN OR POTENTIAL CARCINOGEN: None
NTP: No IARC: No OSHA: No
EXPOSURE CONTROLS: There are no recommended or established exposure levels.
EYES: Wear goggles. Mildly irritating. Excessive contact with powder can cause drying of mucous membranes
of eyes due to absorption of moisture and oils. Contact with product at elevated temperatures can result in
thermal burns.
SKIN: Mildly irritating. Based on product testing product may cause skin sensitization.
INHALATION: Wear a respirator with organic vapor cartridge and built-in particulate filter. Nuisance dust.
Excessive contact with powder can cause drying of mucous membranes of nose and throat due to absorption of
moisture and oils. This material can also cause nasal irritation and nosebleeds.
INGESTION: This product is considered to have a low order of acute oral toxicity.
MEDICAL CONDITIONS AGGRAVATED BY EXPOSURE: Persons with breathing problems or lung disease
should not work in dusty areas unless a physician approves and certifies their fitness to wear respiratory
protection. Preexisting skin and eye disorders may be aggravated by exposure to this product. Preexisting skin
or lung allergies may increase the chance of developing increased allergy symptoms form exposure to this
product.
6 - EMERGENCY & FIRST AID PROCEDURES
EYE CONTACT: Immediately rinse with clean water for 15 minutes. Retract eyelids often. Get medical attention.
SKIN CONTACT: Remove contaminated clothing. Wash skin thoroughly with mild soap and water. Flush with
lukewarm water for 15 minutes. Seek medical attention if ill effect or irritation develops.
EPON 828 DLC-A NATROCHEM MSDS PAGE 3 OF 5
INHALATION: If overcome by exposure, remove victim to fresh air. Provide oxygen if breathing is difficult. Get
medical attention.
INGESTION: Do not induce vomiting. In general, no treatment is necessary unless large quantities of product are
ingested. However, get medical advice.
7 - REACTIVITY DATA
STABILITY: Stable.
MATERIALS TO AVOID- Avoid alteration of product properties. Avoid calcining, which may result in crystalline
formation. Avoid mixing with additives which may alter toxicological properties. Can react vigorously with strong
oxidizing agents, strong Lewis or mineral acids, and strong mineral and organic bases/especially primary and
secondary aliphatic amines.
CONDITIONS TO AVOID- Avoid very high temperatures (>800癈) due to crystalline formation. Reaction with
some curing agents may produce considerable heat. Run-a-way cure reactions may char and decompose the
resin system, generating unidentified fumes and vapors which may be toxic.
HAZARDOUS DECOMPOSITION PRODUCTS: Oxides of carbon may be present when burned. Aldehydes,
acids, and other organic substances may be formed during combustion or degradation at temperatures (500癋).
HAZARDOUS POLYMERIZATION: Will not occur.
8 - SPILL OR LEAK PROCEDURES
Prevent from entering drains, ditches and rivers. Inform the local authorities if this cannot be prevented. Transfer
material to a salvage drum or other proper suitable container for proper disposal. Keep away from ignition
sources. Wear suitable protective equipment.
WASTE DISPOSAL METHOD: In accordance with local, state, and federal regulations.
9 - SPECIAL PROTECTION INFORMATION
RESPIRATORY PROTECTION: Use a respirator such as 3M 9900 or equivalent for protection against
pneumoconiosis producing dusts.
VENTILATION: Provide explosion proof ventilation as required to control airborne dust levels. Ingredients may
emit vapors during normal processing. All possible health effects are not known and individual sensitivities will
vary. Effective exhaust ventilation should always be provided to draw dust, fumes and vapors away from workers
to prevent routine inhalation. Ventilation should be adequate to minimize exposure to dust.
PROTECTIVE GLOVES: Impervious gloves to protect against contact with product.
EYE PROTECTION: Safety goggles.
OTHER PROTECTIVE EQUIPMENT: Protective clothing, eye wash station, safety shower.

10 - SPECIAL PRECAUTIONS
HANDLING AND STORAGE: Store in conditions so that moisture is excluded, preferable in the original
containers kept tightly closed. Under these conditions and at normal temperature, the storage life should be at
least one year. Improper handling can create explosive dust clouds. Eliminate ignition sources, use explosive
proof equipment. Conveying and processing equipment should be spark-proof, well bonded and grounded.
Avoid dust accumulations.
OTHER PRECAUTIONS: Avoid contact with skin and eyes. Wash with soap and water before eating, drinking,
smoking, or using toilet facilities. Launder contaminated clothing before reuse.
