Composition/information on ingredients CAS Number Content (W/W) Chemical name % Fatty acids, tall-oil, reaction products with tetraethylenepentamine % triethylenetetramine % 3,6,9-triazaundecamethylene-1,11-diamine % 2,4,6-tris(dimethylaminomethyl)phenol 3. Hazard identification Emergency overview DANGER: MAY CAUSE BURNS. MAY BE HARMFUL IF INHALED. MAY BE HARMFUL IF SWALLOWED. MAY CAUSE ALLERGIC SKIN REACTION. Keep container tightly closed. Avoid contact with the skin, eyes and clothing. Wash thoroughly after handling. Potential health effects Primary routes of exposure Routes of entry for solids and liquids include eye and skin contact, ingestion and inhalation. Routes of entry for gases include inhalation and eye contact. Skin contact may be a route of entry for liquified gases. Acute toxicity: Information on: 2,4,6-tris(dimethylaminomethyl)phenol Of moderate toxicity after single ingestion. EU-classification Of moderate toxicity after short-term skin contact. Virtually nontoxic after a single ingestion. Irritation: Corrosive! Damages skin and eyes. May cause severe damage to the eyes. Sensitization:

2 Revision date : 2009/04/30 Page: 2/6 May produce an allergic reaction. Sensitization after skin contact possible. Sensitization after skin contact possible. 4. First-aid measures General advice: First aid personnel should pay attention to their own safety. Immediately remove contaminated clothing. If inhaled: After inhalation of dust. Keep patient calm, remove to fresh air, seek medical attention. If on skin: After contact with skin, wash immediately with plenty of water and soap. Under no circumstances should organic solvent be used. If irritation develops, seek medical attention. If in eyes: In case of contact with eyes, rinse immediately with plenty of water and seek medical advice. If swallowed: Rinse mouth immediately and then drink plenty of water, seek medical attention. Do not induce vomiting unless told to by a poison control center or doctor. Note to physician Treatment: Treat according to symptoms (decontamination, vital functions), no known specific antidote, administer corticosteroid dose aerosol to prevent pulmonary odema. 5. Fire-fighting measures Flash point: C (ASTM D3278) Autoignition: 294 C Lower explosion limit: Upper explosion limit: Suitable extinguishing media: foam, water spray, dry extinguishing media, carbon dioxide Unsuitable extinguishing media for safety reasons: water jet Hazards during fire-fighting: carbon dioxide, carbon monoxide, nitrogen oxides, fumes/smoke, corrosive gases/vapours, carbon black Protective equipment for fire-fighting: Wear a self-contained breathing apparatus. Further information: The degree of risk is governed by the burning substance and the fire conditions. Contaminated extinguishing water must be disposed of in accordance with official regulations. 6. Accidental release measures Personal precautions: Avoid contact with skin and eyes. Use personal protective clothing. Handle in accordance with good building materials hygiene and safety practice.

3 Revision date : 2009/04/30 Page: 3/6 Environmental precautions: Contain contaminated water/firefighting water. Do not discharge into drains/surface waters/groundwater. Cleanup: For small amounts: Pick up with suitable appliance and dispose of. Dispose of absorbed material in accordance with regulations. For large amounts: Pick up with suitable appliance and dispose of. Dispose of absorbed material in accordance with regulations. 7. Handling and storage Handling General advice: Avoid inhalation of mists/vapours. Avoid contact with the skin, eyes and clothing. Storage General advice: Keep container tightly closed in a cool, well-ventilated place. 8. Exposure controls and personal protection Personal protective equipment Respiratory protection: Wear a NIOSH-certified (or equivalent) amine/organic vapor respirator. Wear a NIOSH-certified (or equivalent) respirator as necessary. Hand protection: Wear chemical resistant protective gloves. Eye protection: Tightly fitting safety goggles (chemical goggles). Body protection: Body protection must be chosen depending on activity and possible exposure, e.g. apron, protecting boots, chemical-protection suit (according to EN in case of splashes or EN ISO in case of dust). General safety and hygiene measures: Avoid contact with the skin, eyes and clothing. In order to prevent contamination while handling, closed working clothes and working gloves should be used. Handle in accordance with good building materials hygiene and safety practice. When using, do not eat, drink or smoke. Hands and/or face should be washed before breaks and at the end of the shift. At the end of the shift the skin should be cleaned and skin-care agents applied. Gloves must be inspected regularly and prior to each use. Replace if necessary (e.g. pinhole leaks). 9.

Stability and reactivity Conditions to avoid: See MSDS section 7 - Handling and storage. Substances to avoid: strong acids, strong bases, strong oxidizing agents Hazardous reactions: The product is stable if stored and handled as prescribed/indicated. Decomposition products: carbon oxides, nitrogen oxides, aldehydes Thermal decomposition: No decomposition if stored and handled as prescribed/indicated. 11. Toxicological information Sensitization: Can sensitize the skin and/or respiratory tract of allergic persons. May produce an allergic reaction. Genetic toxicity: The substance was mutagenic in various test systems with bacterias and cell cultures; however, these results could not be confirmed in tests with mammals Ecological information Environmental toxicity Other ecotoxicological advice: Ecological data are not available. 13. Disposal considerations Waste disposal of substance: Observe national and local legal requirements. Residues should be disposed of in the same manner as the substance/product. Container disposal: Contaminated packaging should be emptied as far as possible; then it can be passed on for recycling after being thoroughly cleaned.
