Handling and Storage

Safe handling precautions, storage conditions, and workplace requirements

Handling

Assure sufficient ventilation. Observe the rules usually applicable when handling chemicals. Handle in accordance with good industrial hygiene and safety practice. The personal protective equipment used must meet the requirements of Regulation (EU) 2016/425 and amendments (CE certification). If workplace exposure limits are exceeded and/or larger amounts are released (leakage, spilling, dust) the indicated respiratory protection should be used. If there is the possibility of skin/eye contact, the indicated hand/eye/body protection should be used. Do not breathe in vapours or aerosols. Avoid contact with skin and eyes.

Storage

Keep container tightly closed. Protect from moisture.

Hygiene

Observe the rules usually applicable when handling chemicals. Handle in accordance with good industrial hygiene and safety practice.

Fire prevention

Normal measures for preventive fire protection.

08

Exposure Controls / PPE

Occupational exposure limits, engineering controls, and protective equipment

Engineering

Provide for good ventilation if vapours/aerosols are formed. Spray within closed systems only.

Hands

Material: Butyl rubber. Break-through time: >= 480 min Glove thickness: 0.5 mm Material: Natural rubber. Break-through time: >= 30 min Glove thickness: 1.25 mm Additional Information: In case of contact through splashing: Material: Nitrile rubber. Break-through time: >= 30 min Additional Information: In case of contact through splashing: Additional Information: Selection of protective gloves to meet the requirements of specific workplaces., Suitability for specific workplaces should be clarified with protective glove manufacturers., The information is based on our own tests, references from the literature and information from glove manufacturers, or derived by analogy with similar materials., Please observe that the daily duration of usage of a chemical protective glove is in practice far shorter due to the many influencing factors (e.g. temperature, mechanical strain on the glove material) than the permeation time determined acc. EN 374.

Eyes

Safety glasses

Respiratory

In case of dusts/vapours/aerosols being formed or if the limit values like TLV are exceeded: use respiratory equipment with suitable filter (filter type ABEK) or wear a self contained respiratory apparatus. Use only respiratory protection equipment with CE-symbol including four digit test number. The filter class for the respirator must be suitable for the maximum expected contaminant concentration (gas/vapour/aerosol/particulates) that may arise when handling the product. If this concentration is exceeded, self-contained breathing apparatus must be used. Note time limit for wearing respiratory protective equipment.

Skin/Body

suitable protective clothing - Use disposable clothing if appropriate.

Stability and Reactivity

Chemical stability, hazardous reactions, and incompatible materials

Stability

Stable under recommended storage conditions.

Reactivity

No dangerous reaction known under conditions of normal use.

Hazardous reactions

No dangerous reactions known.

Avoid

Hydrolyses on contact with water. In the presence of oxygen and heat, the ethanol forming during the reaction may produce acetaldehyde. Material may form acetaldehyde when heated with inorganic pigments in the presence of air.

Incompatible

Water.

Decomposition

Ethanol in case of hydrolysis. Alcohol formed by hydrolysis lowers the flash point of the product.
