Magna-Tac M-611 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.

Magna-Tac M-611 is specified by Hamilton Standard Div. of United Technologies Corp. for the bonding of treated Teflon to anodized aluminum propeller blade shanks. See Page 2.

Surface Preparation

All bonding surfaces must be thoroughly cleaned, degreased and dried. For plastic surfaces, remove mold release if any.

Preparation of Adhesive

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 M-611 may be used with hardeners which set at room temperatures, at moderate temperatures and at elevated temperatures.

Application

Mixed Magna-Tac M-611 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 UNDER ANY CIRCUMSTANCES!

Methyl Ethyl Ketone may be used for cleaning equipment or wiping up spilled adhesive before curing.
