    Business Information
    Shelf Life Details Scotchcast 2104 resin is stable for a period of one year from date of manufacture providing the Guard Bag (the white aluminized bag) is not opened when stored under the following recommended storage conditions. Store behing present stock in a clean dry place at a temperature of 70°F (21°C) and 40 to 50% relative humidity. Good stock rotation is also recommended. If the guard bag is removed, the shelf life could be reduced to as little as two hours under conditions of high humidity. Scotchcast 2104 is not impaired by freezing: however it should be warmed to at least 32°F (0°C) before being mixed or poured., 3M™ Scotchcast™ Electrical Insulating Resin 2104 has a 2-year shelf life from date of manufacture when stored in the factory-sealed packaging under humidity controlled storage (10°C/50°F to 27°C/80°F and <75% relative humidity).
