IDENTIFICATION <br /> Chemical Product <br /> ICYNENE A-Component for The Icynene Insulation System(GOLD SEAL®) <br /> Manufacturer <br /> ICYNENE,Inc <br /> 6747 Campobello Road <br /> Mississauga,Ontario,LN 2L7 Canada <br /> Emergency Overview <br /> Product Information: 1-800-758-7325. <br /> Transportation Emergency: Canutec 1-613-996-6666. The Icynene Insulation System and GOLD SEAL®are <br /> registered trademarks by the manufacturer,Icynene Inc. <br /> Chemical Product <br /> ICYNENE Two-Component <br /> A-Component for Two-Component Polyurethane Foam System <br /> Product is a urethane foam component that contains a liquified compressed gas blowing agent(Non-Flammable Compressed <br /> Gas). Containers should not be heated above 120°F(49°C)to avoid excessive pressure build-up. <br /> ?. COMPOSITION <br /> Chemical Name(common names) CAS Number Percentaize LDso LCso <br /> 1,1,1,2-Tetrafluoroethane 811-97-2 5 to 10 percent NA NA <br /> (Non-Flammable Compressed Gas, <br /> HFC,Fluorocarbon) 134a <br /> 4,4' -Diphenylmethane 101-68-8 30 to 60 percent NA NA <br /> Diisocyanate(MDI) <br /> Higher Oligomers of MDI 9016-87-9 30 to 60 percent NA NA <br /> (Polymeric MDI) <br /> c <br /> (NOTE: See Section 8 of this MSDS for Exposure Guidelines) <br /> 3. HAZARDS IDENTIFICATION <br /> Physical Hazards <br /> Storage temperature should not exceed 120°F(49°C) in order to avoid excessive pressure build-up and possible <br /> release of contents. Also,MDI will react with water to form CO2 and water insoluble polyureas. This reaction may <br /> be vigorous at elevated temperatures,and could cause dangerous pressure build-up in tightly sealed containers. <br /> Liquid contents froth when released from containers. A-Component has strong adhesive characteristics. If <br /> accidental contact occurs, follow the appropriate first aid procedure described in Section 4 of this MSDS. <br /> Potential Health Effects <br /> The primary adverse health effects of this product are related to the Polymeric Isocyanate(PMDI)component, and,to <br /> a lesseie,the Fluorocarbon(134a)component. Therefore, adequate ventilation and respiratory protection <br /> should 1*provided to avoid exceeding exposure limits listed in Section 8 of this MSDS. Spraying MDI as a mist <br /> d?.rig duplication may increase vapor levels of this material. <br />
