1 Wood Finishes and Adhesives Material Safety Data Sheet Hardener Product and Company Identification Chemical or technical description: Hardener Manufacturer / Casco Adhesives (Asia) Pte Ltd Supplier 14 Sungei Kadut Way Singapore Phone: Composition / Information on ingredients Substance CAS No Contents Classification Diphenylmethane diisocyanate, % Xn; R20, isomeres and Homologes Xi;R36/37/38,R42/43 3. Hazard Identification The preparation is classified as dangerous according to Directive 1999/45/EC and its amendments. Classification : Xn; R20 Xi; R36/37/38 R42/43 Human health hazards : Harmful by inhalation. Irritating to eyes, respiratory system and skin. May cause sensitisation by inhalation and skin contact. 4. First Aid Measures Inhalation Ingestion Skin contact Eye contact Move exposed person to fresh air. Keep person warm and at rest. Maintain an open airway. Loosen tight clothing such as a collar, tie, belt or waistband. In the event of any complaints or symptoms, avoid further exposure. If not breathing, give artificial respiration. If breathing is difficult, administer oxygen. Get medical attention. Wash out mouth with water. Do not induce vomiting unless directed to do so by medical personnel. Get medical attention if adverse health effects persist or are severe. Wash contaminated skin with soap and water. Remove contaminated clothing and shoes. Wash clothing before reuse. In the event of any complaints or symptoms, avoid further exposure. Get medical attention if irritation develops. Check for and remove any contact lenses. Rinse with plenty of running water. Get medical attention. 5. Fire Fighting Measures Extinguishing media Suitable suitable Use dry chemical, CO2, water spray (fog) or foam. Water jet. Date of issue: Date of previous issue:

2 Special exposure hazards Hazardous combustion products Special protective equipment for firefighters In a fire, decomposition may produce toxic gases/fumes. Decomposition products may include the following materials: carbon dioxide carbon monoxide nitrogen oxides Be sure to use an approved/certified respirator or equivalent. 6. Accident Release Measures Personal Precautions Environmental precautions Large spill Small spill Do not touch or walk through spilt material. Avoid contact with eyes, skin and clothing. Avoid breathing vapours of this product. Use suitable protective equipment (section 8). Avoid dispersal of spilt material and runoff and contact with soil, waterways, drains and sewers. Stop leak if without risk. Move containers from spill area. Contain and collect spillage with noncombustible, absorbent material e.g. sand, earth, vermiculite or diatomaceous earth and place in container for disposal according to local regulations (see section 13). Prevent entry into sewers, water courses, basements or confined areas. Contaminated absorbent material may pose the same hazard as the spilt product. Dispose of via a licensed waste disposal contractor. Absorb with an inert material and place in an appropriate waste disposal container. Contaminated absorbent material may pose the same hazard as the spilt product. 7. Handling and Storage Handling Storage Keep from any possible contact with water. The product reacts slowly with water, resulting in the production of carbon dioxide. In closed containers, pressure buildup could result in distortion, expansion and, in extreme cases, bursting of the container. Do not get in eyes or on skin or clothing. Do not breathe vapour or mist. Use only with adequate ventilation. Wear appropriate respirator when ventilation is inadequate. Wash thoroughly after handling. Do not apply the product by spraying. Spray mist is harmful even in small doses. Keep from any possible contact with water. Keep container tightly closed. Keep container in a cool, wellventilated area. Keep away from heat and direct sunlight. Use original container. Date of issue: Date of previous issue:

3 8. Exposure Control/ Personal Protection Exposure limit values Ingredient name Occupational exposure limits 4,4'methylenediphenyl diisocyanate ACGIH TLV (United States, 1/2007). TWA: 0,005 ppm 8 hours. Exposure controls Occupational exposure controls Hygiene measures Respiratory protection Hand protection Eye protection Skin protection Use only with adequate ventilation. If user operations generate dust, fumes, gas, vapour or mist, use process enclosures, local exhaust ventilation or other engineering controls to keep worker exposure to airborne contaminants below any recommended or statutory limits. Ensure that eyewash stations and safety showers are close to the workstation location. Wash hands, forearms and face thoroughly after handling chemical products, before eating, smoking and using the lavatory and at the end of the working period. Wash contaminated clothing before reusing. Wear appropriate respirator when ventilation is inadequate. Type A2 / P2 Butyl rubber gloves. Nitrile gloves. Neoprene gloves. Tightlyfitting goggles Protective clothing. 9.
