VI. High Temperature Durability Data – Metal to Metal Wide Area Overlap Shear

Bonds were made on FPL etched and phosphoric acid anodized 2024-3T bare aluminum and exposed at

350°F (177°C). Overlap shear values were obtained at 75°F (23°C) and at 350°F (177°C) as indicated below.

Primer used 3M™ Scotch-Weld™ Structural Adhesive Primer EC-3917. Tested in accordance with 3M TM C-265

(Aluminum to Aluminum Blister Detection Test).

VII. High Temperature/Humidity Durability Data – Metal to Metal Wide Area Overlap Shear

VIII. Thick Adherend Shear

Scotch-Weld AF 555 Film tested on 1/2" thick FPL etched, Phosphoric Anodized 2024-T3 Aluminum primed with

3M™ Scotch-Weld™ Adhesive Primer EW-5000 AS. Full report available from 3M Technical Service upon request.

3M™ Scotch-Weld™ Structural Adhesive Film AF 555 was exposed at the following temperature/humidity and loads

for the number of days specified below before measuring creep. Bonds were made on FPL etched and phosphoric acid

anodized 2024-T3 bare aluminum – using Scotch-Weld EC-3917 Primer and Scotch-Weld AF 555 Film 0.06M wt.

supported. Specimens prepared in accordance with 3M TM C-265 (Aluminum to Aluminum Blister Detection Test).

IX. Composite to Honeycomb – Short Beam Shear

Structural Adhesive Film

AF 555

X. Composite to Composite – Flatwise Tensile

All properties were measured on 2" X 2" specimens configured with three (3) plies of BMS8-256, Type IV,

Class 2, Style 3K-70-PW co-cured at 350°F on each side of BMS8-124, Type I, Class1, Grade 8.0 (.50 inch

thick) honeycomb core with one ply of Scotch-Weld AF 555 Film at each core/skin interface. Flatwise Tension

Test Blocks were subsequently bonded prior to testing and tested in accordance with MIL-STD-401.

All properties were measured on 3" X 6" specimens configured with three (3) plies of BMS8-256, Type IV,

Class 2, Style 3K-70-PW co-cured at 350°F on each side of BMS8-124, Type I, Class1, Grade 8.0 (.50 inch

thick and transverse with 6" dimension) honeycomb core with one ply of 3M™ Scotch-Weld™ Structural

Adhesive Film AF 555 at each core/skin interface. Beam shear was tested in a three point configuration with

a 4.00 ± 0.05" span with the tool side up (in compression) to MIL-STD-401 guidelines.
