Magna-Tac™ A-39
- Chemical Family
- Epoxy & Epoxy Derivatives
Magna-Tac™ A-39 is a 100% -solids, two-component, solvent-free, formulated epoxy adhesive in paste form specifically designed for metal-to-metal applications and for bonding other rigid materials such as glass, plastics, wood and structural laminates based on glass or fiber reinforced melamine, silicone, polyester, phenolic, epoxy, etc. resins. This adhesive may be cured at room temperature or at elevated temperatures, depending on manufacturing conditions, properties desired and on service requirements for the finished assembly.

- Application
All bonding surfaces must be thoroughly cleaned, degreased and dried. For plastic surfaces, remove mold release if any.; Weigh each part accurately and mix slowly to avoid entrapment of air. Note: Pot life can be lengthened substantially if shallow mixing vessels are used or smaller batches are mixed. Cover mixed material to prevent water absorption Depending upon the end use service requirements of the completed bond, Magna-Tac A-39 may be used with hardeners which set at room temperatures, at moderate temperatures and at elevated temperatures.; Magna-Tac A39 Part A - 70 parts Magna-Tac A39 Part B - 20 parts.; Mixed Magna-Tac A-39 may be applied with trowel, spatula, knife, etc. Apply enough mixed adhesive to fill all cavities and depressions in both surfaces being bonded and to leave about 4 additional mils of adhesive on each side. After proper mating of the components (with slight squeeze out of adhesive), optimum bond line thickness should range from .003 to .006 inch. (Very heavy glue lines may be tolerated up to 0.010 inch - and the adhesive may be cured in heavy sections with very little shrinkage and with good resultant bond strength). Assemble the parts immediately after spreading the adhesive since there are no volatile solvents present to be evaporated.; Clean-up solvent: Do not add thinner to this adhesive. Methyl Ethyl Ketone may be used for cleaning equipment or wiping up spilled adhesive before curing.
