Bonding Film
AF111 for Electronics Applications
Suggested Use
Procedure
Room Temperature Work Life – 3M? Bonding Film AF111 has a room
temperature work life of 4 weeks. Work life is defined as the time at room
temperature that the product will still yield the performance data summarized in
this data sheet if bonds are made and tested per instructions.
Shelf Life – (usable life) of Bonding Film AF111 is:
4 weeks @ 70°F (21°C)
6 months @ 40°F (4°C)
12 months @ 0°F (-18°C)
Cure Conditions – The suggested curing condition for Bonding Film AF111 is 60
minutes at 250°F (121°C). The adhesive may be cured either under pressure or in a
vacuum bag. Alternate suggested cure cycles are shown below.

During cure, pressure is required to keep parts in alignment and in intimate contact.
A minimum of 20 psi is suggested, but higher psi is acceptable if resultant flow
during cure is not excessive.
Bondline Thickness – Unless otherwise specified, the bondline thickness used to
generate the data in this data sheet was 10 mils. Since Bonding Film AF111 will
flow when heated to its curing temperature (… and the higher the cure temperature,
the more the flow…), it may be necessary to insert mechanical spacers (i.e., beads,
wires, stops, etc.) in the bondline to maintain this thickness.
Cold Storage Removal – Important: During storage, Bonding Film AF111 should
be wrapped/sealed in a polyethylene (or similar) wrap/bag. When removing the
wrapped roll or sheets from cold storage, especially if stored below 32°F (0°C),
ample time should be given before handling or overwrap removal to allow for the
roll/sheets to acclimate to room temperature for two reasons:
1) to prevent moisture from condensing on the adhesive surface; and
2) to prevent cracking of the adhesive as it is brittle when cold.
Surface Preparation Prior to Bonding – A thoroughly cleaned, dry, grease-free
surface is essential for maximum performance. Cleaning methods which will
produce a break-free water film on metal surfaces are generally satisfactory.
