For Best Results
In cold weather applications, containers should be kept at 65°F (18°C) for maximum performance. Product temperatures below 55°F (13°C) will experience slow extrusion rates. Not a fire stopping material and should not be used in areas that require fire proof or fire stop materials. Will not adhere to polyethylene (PE), polytetrafluoroethylene(PTFE)/Teflon®, silicone, oils, greases, mold release agents and similar materials. Should not be left exposed but should be covered with at least ½” cement plaster or fire-rated gypsum board or an equivalent barrier that will provide a finished fire rating of 15 minutes or more. Should not be used in contact with chimneys, heater vents, steam pipes or other areas which could be subject to surface temperatures greater than 240°F. Avoid doing hot work or flame cutting around urethane foams. If necessary, follow the recommended industrial procedures.
