    Shelf Life Details Storage: Store at 60-80°F (16-27°C) for maximum storage life. Higher temperatures reduce normal storage life. Lower temperatures cause increased viscosity of a temporary nature. Tubes must be stored in an inverted position (tips down). Rotate stock on a “first in-first-out” basis.Shelf Life: When stored in the original unopened container, under the conditions recommended, this product has a shelf life of 9-12 months @ 40°F (4°C).

  • Best Practices for 3M Tamper-Proof Sealant 1252

    *See Terms of Use Below

    1. Application

      One-part, air drying compound suitable for hand extruding from a collapsible metal tube. Surfaces must be clean, dry and dust free.

    2. Curing

      A 1/8" layer of 3M™ Scotch-Seal Tamper Proof Sealant 1252 is tack-free in 20 seconds and suitable for stamping with ink.

    3. Clean-Up

      Excess sealant may be removed from application equipment with a solvent such as 3M™ Scotch-Grip™ Solvent No. 3 or methyl ethyl ketone (MEK).*

      *Note: When using solvents, extinguish all ignition sources, and follow the manufacturer’s precautions and directions for use.
