Shelf Life Details Store products at 39°F (4°C) or below for maximum storage life. Higher temperatures reduce normal storage life. Rotate stock on a “first-in-first-out” basis. CAUTION: Products are heat sensitive. Storage above 130°F (54°C) may cause an exothermic reaction resulting in evolution of excessive heat, noxious fumes, and possibly fire.;All of these products have a shelf life of 8 months when stored in their unopened containers @ 39°F (4°C) or below; or 12 months @ 0ºF (-18ºC) or below. Shelf Life Temperature (°F) <39 Shelf Life (mon) 8 -

Best Practices for 3M 2214 Hi-Density Gray
-
Surface Preparation
For high 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 directly depends on the substrates, the required bond strength, environmental aging resistance, and requirements determined by the user in light of the user’s particular purpose and method of application.
See vendor technical data sheet for more information.
-
Application
Warm products to room temperature before opening containers to restore proper application consistency and to prevent moisture condensation on adhesive surface. Containers may be stored at room temperature for 1-2 days to thaw. Do not warm at temperatures above 80°F (27°C).
For maximum bond strength, apply product evenly to both surfaces to be joined.
Join the adhesive coated surfaces and heat cure using the following bondline temperature and time for the specific product being used.
Keep parts from moving during cure as contact pressure is necessary.
-
Clean-Up
Cleanup can be accomplished with solvent such as 3M™ Scotch-Grip™ Solvent No. 3 or Methyl Ethyl Ketone.*
*Note: Prior to use of these solvents, extinguish or eliminate any ignition sources and read and follow supplier’s environmental, health, and safety recommendations listed on the MSDS and product label.
