Please be aware that this old REACH registration data factsheet is no longer maintained; it remains frozen as of 19th May 2023.

The new ECHA CHEM database has been released by ECHA, and it now contains all REACH registration data. There are more details on the transition of ECHA's published data to ECHA CHEM here.

First-aid measures

Most important symptoms and effects

Irritating to skin. Harmful: may cause lung damage if swallowed.

Description of first aid measures


In all cases of doubt, or when symptoms persist, seek medical attention.


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.


Immediately flush skin with plenty of water. Remove contaminated clothing and shoes. Get medical attention if

irritation persists. Wash clothing before reuse. Thoroughly clean or destroy contaminated shoes.


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.


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


Hazardous decomposition / combustion products

CO2, Carbon monoxide, 2,2-Dimethylpropane, 2,4,4-Trimethyl-2-pentanol, Isomers of iso-octane.

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. Avoid contact with skin. 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 contact with skin. Avoid Incompatible materials (See Section 10).

Fire and explosion prevention

Use explosion protected equipment. Keep away from sources of ignition - No smoking. 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.

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.


For maximum quality store below: -15 °C.

For safety, store below -5 °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


In case of insufficient ventilation wear suitable respiratory equipment (respirator with Filter A).


Wear suitable protective gloves of neoprene or synthetic rubber.


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: 15 °C. Contact with incompa tible

substances can cause decomposition at or below the SADT 15 °C.

To insure against possible exothermic self-accelerating decomposition, storage temperatures must not exceed

emergency temperature of 5 °C.

Conditions to avoid

Under no circumstances should this product be exposed to temperatures above the emergency temperature of

5 °C. If the product temperature exceeds 5 °C all a vailable means shall be used to bring the temperature under

control and the emergency procedures shall be started. Emergency procedures will vary depending on

conditions. Contact Akzo Nobel for assistance with developing an emergency response plan.

To maintain quality store in original closed container below: -15 °C.

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

2,2-Dimethylpropane, 2,4,4-Trimethyl-2-pentanol, Isomers of iso-octane.

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


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.
