into sewers, storm drains, and watercourses. Use caution after fire is

extinguished, vapors or liquid may reignite. Notify appropriate state and local

agencies.

UNUSUAL FIRE AND EXPLOSION HAZARDS: Pressure may build up in tightly closed

containers exposed to fire which may result in rupture. Keep containers cooled

with water spray. Vapors may travel a considerable distance to a source of

ignition or collect in low areas.

other toxic gases.

HAZARDOUS POLYMERIZATION: Will not occur.

==================== SECTION VI - HEALTH HAZARD DATA =======================

INHALATION HEALTH RISKS AND SYMPTOMS OF EXPOSURE: Effects vary among individuals

and may include headache, dizziness, nausea, irritation of the nose, throat, and

respiratory tract, and incoordination. Severe overexposure may produce

anesthesia or unconsciousness.

SKIN AND EYE CONTACT HEALTH RISKS AND SYMPTOMS OF EXPOSURE: Eye contact may

cause irritation, redness, and tearing, and blurred vision. Skin contact may

cause irritation and redness. Long term skin exposure may dry and defat the

skin, causing cracking, and in severe cases, dermatitis.

INGESTION HEALTH RISKS AND SYMPTOMS OF EXPOSURE: Ingestion can cause

gastrointestinal irritation, vomiting, nausea, and diarrhea.

HEALTH HAZARDS (ACUTE AND CHRONIC): Breathing high concentrations of aerosols or

mists of this material may cause nausea and irritation of the nose, throat, and

respiratory tract. Acute overexposure to solvent fumes during air drying of

this product may cause headache, dizziness, nausea, and loss of coordination.

Chronic overexposure to solvent fumes may cause central nervous system damage.

Breathing high concentrations of aerosols or mists of this material may cause

nausea and irritation of the nose, throat, and respiratory tract. NOTE: this

product contains trace amounts of residual ethylene oxide (CAS 75218, <0.03 ppm)

and epichlorohydrin (CAS 106898 <0.0003 ppm) which have been identified by

California Proposition 65 as either a carcinogenic or reproductive hazard. At

the trace levels contained in this product, they should present no hazard with

normal industrial use.

SIGNIFICANT DATA ON MIBK WITH POSSIBLE RELEVANCE TO HUMANS

In tests with laboratory animals, methyl isobutyl ketone produced evidence of

embryofetal toxicity at exposure levels which were toxic to mothers, but no

evidence was obtained for teratogenicity, or for embryofetal toxicity, at levels

which did not affect the mothers. Results from five mutagenicity assays with

different genetic endpoints indicate that methyl isobutyl ketone does not

produce activity typical of that of chemical mutagens. Additional studies have

shown that methyl isobutyl ketone is toxic if aspirated. It is known to enhance

the neurotoxicity of linear 6 carbon solvents.

CARCINOGENICITY: NTP: Yes IARC MONOGRAPHS: Yes OSHA REGULATED: No

CHRONIC EFFECTS OF CARBON BLACK OVEREXPOSURE

The carbon black component of this formula is an IARC listed Group 2B substance,

considered by IARC to be a "Possible human carcinogen". Carbon black is not

designated as a carcinogen by the U.S. National Toxicology Program (NTP) or the

U.S. Occupational Safety and Health Administration (OSHA). The American

Conference of Governmental Industrial Hygienists (ACGIH) classifies carbon black

as A4, "Not classifiable as a human carcinogen". Carbon black is not presently

listed by California Proposition 65, but the California Office of Environmental

Health Hazard Assessment (OEHHA) published on October 29, 1999 a Notice of

Intent to List "Carbon Black (airborne particles of respirable size)" as a

"substance known to the State to cause cancer".

CHRONIC EFFECTS OF ETHYLBENZENE OVEREXPOSURE

The International Agency for Research on Cancer (IARC) has evaluated

ethylbenzene (a component of xylol) and classified it as a possible human

carcinogen (Group 2B) based on sufficient evidence for carcinogenicity in

experimental animals, but inadequate evidence for cancer in exposed humans.

CHRONIC EFFECTS OF CRYSTALLINE SILICA AS QUARTZ

The International Agency for Research on Cancer (IARC) has evaluated crystalline

silica, inhaled as quartz, and classified it as a confirmed human carcinogen.

The National Toxicology Program (NTP) classifies quartz as "reasonably

anticipated to be a human carcinogen".

MEDICAL CONDITIONS GENERALLY AGGRAVATED BY EXPOSURE: Overexposure to solvent

fumes may aggravate anesthesia, respiratory tract disease or pre-existing lung

disorders, nausea, and vomiting.

EMERGENCY AND FIRST AID PROCEDURES: INHALATION OVEREXPOSURE: Remove person to

fresh air, If breathing stops, apply artificial respiration and seek immediate

medical attention. NOTE: Use supplied-air respirator for rescue in enclosed

areas. EYE CONTACT: Flush with large amounts of tepid water for at least 15

minutes, get medical attention. INGESTION: Do not induce vomiting, if aspirated

material can cause chemical pneumonitis or pulmonary edema. Drink 2 glasses of

milk or water to dilute and contact physician or poison center. SKIN: Wash with

soap and water, avoid repeated contact.

=========== SECTION VII - PRECAUTIONS FOR SAFE HANDLING AND USE ============

STEPS TO BE TAKEN IN CASE MATERIAL IS RELEASED OR SPILLED: Remove all sources of

ignition. Dike to prevent entry into sewers or surface waters. Recover free

liquid by shoveling into container using non-sparking tools, or add absorbent

such as sand or earth to spill and sweep up. Provide ventilation, wear a

respirator. Notify proper authorities if spill contaminates land or waterways.

WASTE DISPOSAL METHOD: Store soaked rags or absorbent material in airtight

containers to prevent spontaneous combustion of material. Absorbent materials

may emit flammable vapors. Dispose of in chemical landfill or incinerate

assuring conformity to all applicable local, state, and federal governing

regulations.

PRECAUTIONS TO BE TAKEN IN HANDLING AND STORAGE: Do not expose to flame, sparks,

or other sources of ignition. Use non-sparking alloy tools and explosion-proof

equipment for handling. The need for grounding and bonding of containers in

accordance with OSHA 29 CFR 1910.106 and NFPA 77 should be assessed before

transferring product. Store inside away from extreme temperature variations.

Protect containers from physical damage. Keep containers tightly closed when

not in use. Do not inhale vapors or mists, use with adequate ventilation and

wear a respirator. Do not store with food or animal feed.

OTHER PRECAUTIONS: Do not cut, weld, grind, drill, solder, or braze on or near

containers whether full or empty. Do not reuse containers without professional

reconditioning and testing. Do not remove warning labels from containers.

===================== SECTION VIII - CONTROL MEASURES ======================

RESPIRATORY PROTECTION: Using this product in poorly ventilated areas may

require the use of a respirator. Use Mine Safety Appliance respirator #448849

with organic vapor cartridge and mist filter (or equivalent) if air monitoring

demonstrates that the concentration of listed hazardous materials exceeds the

recommended TLV's. In enclosed areas where ventilation is not used, wear a Mine

Safety Appliance #475217 pressure/demand air-supplied respirator or equivalent.

VENTILATION: Use good general mechanical ventilation and local exhaust adequate

to reduce the concentration of vapors or mists of the listed hazardous materials

to below the Threshold Limit Value(s) and the Lower Explosion Limit.

Ventilation equipment must be explosion proof.

PROTECTIVE GLOVES: Use of gloves is recommended, use chemically resistant type.

EYE PROTECTION: Use is recommended, use splash goggles or full face shields as

necessary.

OTHER PROTECTIVE CLOTHING: Use impervious apron or coveralls to prevent

contaminating street clothes which may result in prolonged exposure. The use of

head caps or helmets is recommended.

WORK AND HYGIENIC PRACTICES: Eye washes and safety showers in the workplace are

recommended. Practice good industrial hygiene when using this product: After

using this product, do not smoke or eat until washing thoroughly. Remove

saturated clothing or shoes at once and launder before reuse.
