The likelihood of this happening depends on your joint design, the mass of material cured, and the ability for heat to be dissipated by the substrates. 1. 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). 2. 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. For specific surface preparations on common substrates, see the section on surface preparation. 3. Use gloves to minimize skin contact and do not use solvents for cleaning hands. 4. For maximum bond strength, apply product evenly to both surfaces to be joined. 5. Join the adhesive coated surfaces and heat cure using the following bondline temperature and time for the specific product being used. Any of the following cure cycles will result in a full cure. 3M™ Scotch-Weld™ Adhesive 2214 Regular 3M™ Scotch-Weld™ Adhesive 2214 Hi-Temp 10 min @ 300°F (149°C)

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 an d follow supplier’s environmental, health, and safety recommendations listed on the MSDS and product label. Surface Preparation The following cleaning methods are suggested for common surfaces: Steel: 1. Wipe free of dust with oil-free solvent such as Methyl Ethyl Ketone.* 2. Sandblast or abrade using clean fine grit abrasives. 3. Wipe again with solvent to remove loose particles. Aluminum: 1. Vapor Degrease – Perchloroethylene* condensing vapors for 5-10 minutes. 2. Alkaline Degrease – Oakite 164 solution (9-11 oz./gallon water) at 190°F ± 10°F (87°C ± 5°C) for 10-20 minutes. Rinse immediately in large quantities of cold running water. 3.

Rinse – Rinse panels in clear running tap water. 5. Dry – Air dry 15 minutes; force dry 10 minutes at 150°F ± 10°F (66°C ± 5°C). 6. If primer is to be used, it should be applied within 4 hours after surface preparation. Plastics: 1. Solvent wipe with Isopropyl Alcohol.* 2. Abrade using clean fine grit abrasives. 3. Solvent wipe with Isopropyl Alcohol.* Rubbers: 1. Solvent wipe with Methyl Ethyl Ketone.* 2. Abrade using clean fine grit abrasives. 3. Solvent wipe with Methyl Ethyl Ketone.* Glass: 1. Solvent wipe with acetone or Methyl Ethyl Ketone.*

- 6 - Note: For glass applications which will be subjected to high moisture/humidity conditions, 3M™ Scotch-Weld™ Primer EC-3901 should be used to prime the glass. *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. Application/Equipment Information These products may be applied by spatula, trowel, or flow equipment. Dispensing equipment is available for intermittent or production line use. These systems are ideal because of their variable shot size and flow rate characteristics and are adaptable to most applications. For more information, contact your local 3M sales representative.
