    Business Information
    Shelf Life Details Store in original containers at or below 80°F (27°C).;These products can be expected to have at least nine months shelf life. At lower temperature, the shelf life will be longer. Lower temperatures cause increased viscosity of a temporary nature and also will cause water to condense on the container. Therefore, containers stored at low temperatures should be allowed to return to room temperature before opening so that water does not come in contact with the adhesive and cause adhesive gelation.
    Shelf Life Temperature (°F) <81
    Shelf Life (mon) >9

  • Best Practices for 3M CA7

    *See Terms of Use Below

    1. Surface Preparation

      For optimum strength structural bonds, paint, oxide films, oils, dust, mold release agents and all other surface contaminants must be completely removed. However, the amount of surface preparation depends on the required bond strength and the environmental aging resistance desired by the user.
