XIAMETER XIAMETER® Material Safety Data Sheet Version: 1.4 Revision Date: 2005/06/01 DAP® 100% SILICONE RUBBER SEALANT ALUMINUM, 8643 1. PRODUCT AND COMPANY IDENTIFICATION -------------------------------------------------------------------------------- Dow Corning Corporation 24 Hour Emergency Telephone: (989) 496-5900 South Saginaw Road Customer Service: (989) 496-6000 Midland, Michigan 48686 Product Disposal Information: (989) 496-6315 CHEMTREC: (800) 424-9300 MSDS No.: 04061405 Revision Date: 2005/06/01 Generic Description: Silicone elastomer Physical Form: Paste Color: See product name Odor: Acetic acid odor NFPA Profile: Health 2 Flammability 1 Instability/Reactivity 0 Note: NFPA = National Fire Protection Association 2. OSHA HAZARDOUS COMPONENTS -------------------------------------------------------------------------------- CAS Number Wt % Component Name 17689-77-9 1.0 - 5.0 Ethyltriacetoxysilane 4253-34-3 1.0 - 5.0 Methyltriacetoxysilane The above components are hazardous as defined in 29 CFR 1910.1200. 3. HAZARDS IDENTIFICATION -------------------------------------------------------------------------------- POTENTIAL HEALTH EFFECTS Acute Effects Eye: Direct contact may cause moderate irritation. Skin: May cause moderate irritation. Inhalation: Material is not likely to present an inhalation hazard at ambient conditions. However, if material is heated or high vapor/aerosol concentrations are attained, central nervous system depression may occur, which is characterized by drowsiness, dizziness, confusion or loss of coordination. Oral: Low ingestion hazard in normal use. Prolonged/Repeated Exposure Effects Skin: No known applicable information. Inhalation: No known applicable information. Oral: Repeated ingestion or swallowing large amounts may injure internally. Signs and Symptoms of Overexposure No known applicable information. Medical Conditions Aggravated by Exposure No known applicable information. The above listed potential effects of overexposure are based on actual data, results of studies performed upon similar compositions, component data and/or expert review of the product. Please refer to Section 11 for the detailed toxicology information. 4. FIRST AID MEASURES -------------------------------------------------------------------------------- Eye: Immediately flush with water for 15 minutes. Get medical attention. Skin: Remove from skin and wash thoroughly with soap and water or waterless cleanser. Get medical attention if irritation or other ill effects develop or persist. Inhalation: Material is not likely to present an inhalation hazard at ambient conditions. If material is heated or vapor/mist/dust/fumes are generated, care should be taken to prevent inhalation. In case of exposure to vapor/mist/fumes, move to fresh air. Oral: Get medical attention. Comments: Treat according to person's condition and specifics of exposure. 5. FIRE FIGHTING MEASURES -------------------------------------------------------------------------------- Flash Point: > 212 F / > 100 C (Closed Cup) Auto ignition Temperature: Not determined. Flammability Limits in Air: Not determined. Extinguishing Media: On large fires use dry chemical, foam or water spray. On small fires use carbon dioxide (CO2), dry chemical or water spray. Water can be used to cool fire exposed containers. Fire Fighting Measures: Self-contained breathing apparatus and protective clothing should be worn in fighting large fires involving chemicals. Determine the need to evacuate or isolate the area according to your local emergency plan. Use water spray to keep fire exposed containers cool. Unusual Fire Hazards: None Hazardous Decomposition Products Thermal breakdown of this product during fire or very high heat conditions may evolve the following hazardous decomposition products: Carbon oxides and traces of incompletely burned carbon compounds. Silicon dioxide. Formaldehyde. Metal Oxides. Nitrogen oxides. Sulfur oxides. Chlorine compounds. 6. ACCIDENTAL RELEASE MEASURES -------------------------------------------------------------------------------- Containment/Clean up: Observe all personal protection equipment recommendations described in Sections 5 and 8. Wipe up or scrape up and contain for salvage or disposal. Clean area as appropriate since spilled materials, even in small quantities, may present a slip hazard. Final cleaning may require use of steam, solvents or detergents. Dispose of saturated absorbent or cleaning materials appropriately, since spontaneous heating may occur. Local, state and federal laws and regulations may apply to releases and disposal of this material, as well as those materials and items employed in the cleanup of releases. You will need to determine which federal, state and local laws and regulations are applicable. Sections 13 and 15 of this MSDS provide information regarding certain federal and state requirements. Note: See section 8 for Personal Protective Equipment for Spills. Call (989) 496-5900, if additional information is required. 7. HANDLING AND STORAGE -------------------------------------------------------------------------------- Use with adequate ventilation. Product evolves acetic acid (HOAc) when exposed to water or humid air. Provide ventilation during use to control HOAc within exposure guidelines or use respiratory protection. Avoid eye contact. Avoid skin contact. Do not take internally. Avoid breathing vapor. Keep container closed. Use reasonable care and store away from oxidizing materials. Keep container closed and store away from water or moisture. 8. EXPOSURE CONTROLS/PERSONAL PROTECTION Component Exposure Limits CAS Number Component Name Exposure Limits 17689-77-9 Ethyltriacetoxysilane See acetic acid comments. 4253-34-3 Methyltriacetoxysilane See acetic acid comments. Acetic acid is formed upon contact with water or humid air. Provide adequate ventilation to control exposures within guidelines of OSHA PEL: TWA 10 ppm and ACGIH TLV: TWA 10 ppm, STEL 15 ppm. Engineering Controls Local Ventilation: Recommended. General Ventilation: Recommended. Personal Protective Equipment for Routine Handling Eyes: Use proper protection - safety glasses as a minimum. Skin; Wash at mealtime and end of shift. Contaminated clothing and shoes should be removed as soon as practical and thoroughly cleaned before reuse. Chemical protective gloves are recommended. Suitable Gloves: Butyl Rubber. Nitrile Rubber. Inhalation; Use respiratory protection unless adequate local exhaust ventilation is provided or exposure assessment demonstrates that exposures are within recommended exposure guidelines. IH personnel can assist in judging the adequacy of existing engineering controls. Suitable Respirator: Respiratory protection is not needed under ambient conditions. If vapor/mist/fumes are generated when material is heated or handled, the following is advised. General and local exhaust ventilation is recommended to maintain vapor exposure below recommended limits. Where concentrations are above recommended limits or are unknown, appropriate respiratory protection should be worn. Follow OSHA respirator regulations (29 CFR 1910.134) and use NIOSH/MSHA approved respirators. Personal Protective Equipment for Spills Eyes; Use full face respirator. Skin: Wash at mealtime and end of shift. Contaminated clothing and shoes should be removed as soon as practical and thoroughly cleaned before reuse. Chemical protective gloves are recommended. Inhalation/Suitable Respiratory protection recommended. Follow OSHA Respirator Respirator: Regulations (29 CFR 1910.134) and use NIOSH/MHSA approved respirators. Protection provided by air purifying respirators against exposure to any hazardous chemical is limited. Use a positive pressure air supplied respirator if there is any potential for uncontrolled release, exposure levels are unknown, or any other circumstance where air purifying respirators may not provide adequate protection. Precautionary Measures: Avoid eye contact. Avoid skin contact. Do not take internally. Avoid breathing vapor. Keep container closed. Use reasonable care. Comments: Product evolves acetic acid (HOAc) when exposed to water or humid air. Provide ventilation during use to control HOAc within exposure guidelines or use respiratory protection. When heated to temperatures above 150 C (300 F) in the presence of air, product may form formaldehyde vapors. Physical and health hazard information is readily available from Dow Corning Corporation and the Material Safety Data Sheet. Note: These precautions are for room temperature handling. Use at elevated temperature or aerosol/spray applications may require added precautions. 9.
