First-aid measures

Most important symptoms and effects
Possible risk of irreversible effects.
Description of first aid measures
General
In all cases of doubt, or when symptoms persist, seek medical attention.
Inhalation
Remove to fresh air. If not breathing, give artificial respiration. Oxygen may additionally be given, by trained
personnel, if it is available. Get medical attention if symptoms occur.
Skin
Flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical attention if irritation
develops and persists. Wash clothing before reuse. Thoroughly clean or destroy contaminated shoes.
Eye
Immediately flush eyes with plenty of water. If easy to do, contact lenses should be removed during the
flushing, by trained personnel. Occasionally hold the eyelids apart during the flushing to ensure rinsing the
entire surface of the eye and lids with water. Get medical attention if irritation develops and persists.
Ingestion
Call a physician or a poison control center immediately. Do NOT induce vomiting unless directed to do so by
medical personnel. If vomiting occurs, the patient should lie on their left side while vomiting to reduce the risk of
aspiration. Never give anything by mouth to an unconscious or convulsing person.
Indication of any immediate medical attention and special treatment needed
Persons with pre-existing skin, respiratory, and/or central nervous system disease may be at increased risk if exposed
to this material.
Condition of the patient should be carefully monitored. Aspiration of this product during induced emesis can result in
lung injury. If evacuation of stomach contents is considered necessary, use method least likely to cause aspiration,
such as gastric lavage after endotracheal intubation. Contact a Poison Control Center for additional treatment
information. Treat patient symptomatically.

Fire-fighting measures

Extinguishing media
waterspray, foam, sand, dry chemical powder, CO2.
Unsuitable extinguishing media
halones.
Hazardous decomposition / combustion products
CO2, Carbon monoxide.
Acetone, Methane, tert-Butanol.
Protective equipment
Firefighters must wear fire resistant protective equipment. Wear approved respirator and protective gloves.
Other information
Evacuate all non-essential personnel. Extinguish a small fire with powder or carbon dioxide then apply water to prevent
re-ignition. Cool closed containers with water. Water used to extinguish a fire should not be allowed to enter the
drainage system or water courses. After a fire, ventilate thoroughly the area and soak with water, clean the walls and
metallic surfaces.
Fire and explosion hazard
CAUTION: reignition may occur. Decomposition under effect of heating (See also Section Hazardous decomposition
products). If involved in a fire, it will support combustion. Vapours may form explosive mixtures with air. In case of fire
and/or explosion do not breathe fumes.

Accidental release measures

Personal precautions
Do not breathe fumes/vapour. For personal protection see Section 8.
Environmental precautions
Do not allow to enter drains or water courses.
Methods and material for containment and cleaning up
Stop leakage if possible. Eliminate all sources of ignition, and do not generate flames or sparks. Take precautionary
measures against static discharges. Transfer remaining product from leaking container to a clean and suitable
container. Cover the remainder with inert absorbent (e.g. vermiculite) for disposal. Keep contents moist. The waste
should NOT be confined. Flush surroundings with large amounts of water and soap.
Other information
CAUTION: reignition may occur. Vapours are heavier than air and may spread along floors. Vapours may travel to a
source of ignition and flash back. Evacuate personnel to safe area.

Handling and storage

Precautions for safe handling
Never weigh out in the storage room. When using do not eat, drink or smoke. Do not pipet by mouth. Do not breathe
fumes/vapour. Handle in well ventilated areas. Eliminate all sources of ignition, and do not generate flames or sparks.
Take precautionary measures against static discharges. Apply earthing when transferring from one container to
another. Keep away from reducing agents (e.g. amines), acids, alkalies and heavy metal compounds (e.g.
accelerators, driers, metal soaps). Keep product and emptied container away from heat and sources of ignition.
Confinement must be avoided. Avoid Incompatible materials (See Section 10).
Fire and explosion prevention
Use explosion protected equipment. Keep away from sources of ignition - No smoking. Vapours are heavier than air
and may spread along floors. Use non-sparking tools in area's where explosive vapor air mixtures may occur. Do not
cut or weld on or near this container even when empty. Blanketing the product with nitrogen reduces the flammability,
but is not fully effective above 55°C (131°F).
Conditions for safe storage
Store in accordance with local/national regulations. Keep away from food, drink and animal feedingstuffs. Store in a
dry well ventilated place away from sources of heat and direct sunlight. Store separate from other chemicals. Keep
only in the original container. Keep container upright to prevent leakage.
Storage
Avoid temperatures below -30 °C. If product freezes or separates, contact Akzo Nobel.
For maximum quality store below: 40 °C.
Other information
It is recommended to use electrical equipment of temperature group T3. However, autoignition can never be excluded.
Wash hands thoroughly after handling or contact. Keep working clothing separately and do not take them home.

Exposure controls / personal protection

Control parameters
Ensure good ventilation and local exhaustion of the working area. Explosion proof ventilation recommended.
Personal protection
Respiratory
In case of insufficient ventilation wear suitable respiratory equipment (respirator with Filter A).
Hand
Wear suitable protective gloves of neoprene or synthetic rubber.
Eye
Wear eye/face protection.
Skin and body
Wear suitable protective clothing.
Other information
Emergency-shower and facilities for rinsing eyes must be accessible. Launder clothes before reuse.

Stability and reactivity

Chemical stability
SADT - (Self accelerating decomposition temperature) is the lowest temperature at which self accelerating
decomposition may occur with a substance in the packaging as used in transport.
A dangerous self-accelerating decomposition reaction and, under certain circumstances, explosion or fire can
be caused by thermal decomposition at and above the following temperature: 80 °C. Contact with incompatible
substances can cause decomposition at or below the SADT 80 °C.
Conditions to avoid
Avoid temperatures below -30 °C.
To maintain quality store in original closed container below: 40 °C.
A high degree of confinement must be avoided.
Incompatible materials
Avoid contact with rust, iron and Copper. Contact with incompatible materials such as acids, alkalies, heavy metals
and reducing agents will result in hazardous decomposition. Do not mix with peroxide accelerators. Use only Stainless
steel 316, PP, polyethylene or glass-lined equipment. Contact Akzo Nobel for more information.
Possibility of hazardous reactions
Polymerization does not occur.
Hazardous decomposition products
Hazardous decomposition products; Acetone, Methane, tert-Butanol.
Other information
Emergency procedures will vary depending on conditions. The customer must have an emergency response plan in
place. Contact Akzo Nobel for assistance with developing an emergency response plan.

Disposal considerations

Product
Due to the high risk of contamination recycling/recovery is not recommended. Waste disposal in accordance with
regulations (most probably controlled incineration).
Contaminated packaging
According to local regulations. Emptied container might retain product residues. Follow all warnings even after the
container is emptied. Do not shred containers before they are thoroughly cleaned from product residues. Do not wash
residues into drains or other waterways.
