COMPOSITION / INFORMATION ON INGREDIENTS Hazardous Component(s) CAS Number Percentage* Ethyl acetate 141-78-6 30 - 60 Methylene chloride 75-09-2 10 - 30 Butane 106-97-8 10 - 30 Propane 74-98-6 10 - 30 Solvent naphtha (petroleum), light aliphatic, low benzene content 64742-89-8 5 - 10 Copper 7440-50-8 1 - 5 Acetone 67-64-1 1 - 5 * Exact percentage is a trade secret. Concentration range is provided to assist users in providing appropriate protections. 4. FIRST AID MEASURES Inhalation: Move to fresh air. If breathing is difficult, give oxygen. If not breathing, give artificial respiration. Get medical attention. Skin contact: Immediately flush skin with plenty of water (using soap, if available). Remove contaminated clothing and footwear. Get medical attention. Wash clothing before reuse. Eye contact: Rinse immediately with plenty of water, also under the eyelids, for at least 15 minutes. Get medical attention. Ingestion: DO NOT induce vomiting unless directed to do so by medical personnel. Never give anything by mouth to an unconscious person. Get medical attention. Symptoms: See Section 11. 5. FIRE FIGHTING MEASURES Extinguishing media: Foam, dry chemical or carbon dioxide. Special firefighting procedures: Water should be used to cool closed containers to prevent pressure build-up and possible autoignition or explosion when exposed to extreme heat. Wear self-contained breathing apparatus and full protective clothing, such as turn- out gear. IDH number: 502911 Product name: LOCTITE SI 7657 FLANGE SEALANT known as Copper Gasket Adhesive Hi-Temp Page 3 of 8 Unusual fire or explosion hazards: Contents under pressure. Do not handle or store near an open flame, heat or other sources of ignition. Exposure to temperatures above 49?C (120?F) may cause container to burst. Do not puncture or incinerate pressurized containers. Vapors may accumulate in low or confined areas, travel considerable distance to source of ignition, and flash back. Hazardous combustion products: Oxides of carbon. Hydrocarbons. Hydrogen chloride. Chlorine. Phosgene. Irritating vapors. 6. ACCIDENTAL RELEASE MEASURES Use personal protection recommended in Section 8, isolate the hazard area and deny entry to unnecessary and unprotected personnel. Environmental precautions: Do not allow product to enter sewer or waterways. Clean-up methods: Remove all sources of ignition. Keep unnecessary personnel away. Ensure adequate ventilation. Wear appropriate personal protective equipment. Soak up with inert absorbent material (e.g. sand, silica gel, acid binder, universal binder, sawdust). Scrape up as much material as possible. Store in a closed container until ready for disposal. Refer to Section 8 "Exposure Controls / Personal Protection" prior to clean up. 7. HANDLING AND STORAGE Handling: During use and until all vapors are gone: Keep area ventilated - do not smoke; extinguish all flames, pilot lights, and heaters; turn off stoves, electrical tools and appliances, and any other sources of ignition. Prevent contact with eyes, skin and clothing. Do not breathe vapor and mist. Wash thoroughly after handling. Do not puncture or incinerate pressurized containers. Refer to Section 8. Storage: Do not store above 49 ?C (120 ?F). Keep in a cool, well ventilated area away from heat, sparks and open flame. Keep container tightly closed until ready for use.
