Miscellaneous Test Data – 3M™ Scotch-Weld™ Structural Adhesive Film AF 30 (10 mil)/

3M™ Scotch-Weld™ Structural Adhesive Primer EC-1660

Storage Life Testing

Individual results of static shear tests made on 1/2" (12.7 mm) lapjoint specimens of 0.063" (1.60 mm) clad

2024-T3 aluminum bonded with the Scotch-Weld AF 30/Scotch-Weld EC-1660 system stored 90 days at standard

temperature (70-80°F [21-27°C]) prior to bonding.

1. Overlap shear at 75°F ± 2°F (24°C ± 1.1°C) average of 21 specimens – 4130 psi (28.4 MPa).

2. Overlap shear at 180°F ± 2°F (82°C ± 1.1°C) average of 21 specimens – 2280 psi (15.7 MPa).

Individual shear strength results after 30 day exposure to salt spray were made on 1/2" (12.7 mm) lapjoint

specimens of 0.063" clad 2024-T3 aluminum bonded with Scotch-Weld AF 30/Scotch-Weld EC-1660 stored 90

days at standard temperature (70-80°F [21-27°C]) prior to bonding.

1. Tested at 75°F ± 2°F (24°C ± 1.1°C) average of 12 specimens – 4040 psi (27.8 MPa).

2. Controls tested at 75°F ± 2°F (24°C ± 1.1°C) – 4020 psi (27.7 MPa).

Aluminum to Aluminum T-Peel (In addition to MMM-A-132 requirements)

T-Peel bonds consist of two Scotch-Weld EC-1660 primed 8" x 8" x .020" (203.2 mm x 203.2 mm x .508 mm)

2024-T3 clad panels bonded together with a 6" x 8" (152.4 mm x 203.2 mm) section of film. This panel is then cut

into 1" x 8" (25.4 mm x 203.2 mm) T-Peel specimens which are peeled at a 90° angle to the bond line with a jaw

separation rate of 20"/minute (508 mm/minute).

Aluminum to Aluminum Overlap Shear (In addition to MMM-A-132 requirements)

The following data shows typical values obtained with Scotch-Weld AF 30 (10 mil) with Scotch-Weld EC-1660 when

tested at temperatures other than those required by MMM-A-132. All properties were measured on 1" (25.4 mm)

wide, 1/2" (12.7 mm) overlap specimens cut from .063" (1.60 mm) thick, 4" x 7" (101.6 mm x 177.8 mm) primed

and bonded panels of 2024-T3 clad aluminum. Tests were conducted per MMM-A-132 Type 1 requirements.
