Substrates and Testing
p Shear (ASTMD 1002-72)
Overlap shear (OLS) strengths were measured on 1 in. wide 1/2 in. overlap specimens. Thesebonds were made individually using 1 in. x 4 in. pieces of substrate except for aluminum. Twopanels 0.063 in. thick, 4 in. x 7 in. of 2024T-3 clad aluminum were bonded and cut into 1 samples after 24 hours. The thickness of the bondline was 0.005-0.008 in. All strengthswere measured at 73°F (23°C) except where noted.
The separation rate of the testing jaws was 0.1 in. per minute for metals, 2 in. per minute forplastics and 20 in. per minute for rubbers. The thickness of the substrates were: steel, 0.060 in.;other metals, 0.05-0.064 in.; rubbers, 0.125 in.; plastics, 0.125 in.B.T-peel (ASTM D 1876-61T)
T-peel strengths were measured on 1 in. wide bonds at 73°F (23°C). The testing jaw separationrate was 20 inches per minute. The substrates were 0.032 in. Peel (ASTM D 3167)
Bell peel strengths were measured on 1/2 in. wide bonds at the temperatures noted. The testingjaw separation rate was 6 in. per minute. The bonds are made with 0.064 in. bonded to 0.025 Cycle
With the exception of Rate of Strength Build-Up Tests, all bonds, were cured 7 days at 73°F(23°C) at 50% RH before testing or subjected to further conditioning or environmental um, Overlap Shear, at Temperature (PSI)

Handling/ApplicationInformation
Directions for Use
3M™Scotch-Weld™Epoxy Adhesives DP460 Off-White and DP460 NS aresupplied in dual syringe plastic duo-pak cartridges as part of the 3M™EPX™
Applicator System. The duo-pak cartridges are supplied in 37 ml, 200 ml and 400 mlconfigurations. To use the 37 ml cartridge simply insert the duo-pak cartridge into theEPX applicator and start the plunger into the cylinders using light pressure on thetrigger. Next, remove the duo-pak cartridge cap and expel a small amount of adhesiveto be sure both sides of the duo-pak cartridge are flowing evenly and freely. If
simultaneous mixing of Part A and Part B is desired, attach the EPX mixing nozzle tothe duo-pak cartridge and begin dispensing the adhesive.
With the 200 ml and 400 ml cartridges, the nozzle must be attached before dispensingany material to prevent unmixed adhesive from getting into the applicator cartridgeholder. A small quantity of material should be discarded until uniform color,consistency of product and even flow is evident.
When mixing Part A and Part B manually, the components must be mixed in theratio indicated in the typical uncured properties section. Complete mixing of the twocomponents is required to obtain optimum properties.
Two-part mixing/proportioning/dispensing equipment is available for intermittent orproduction line use. These systems are ideal for line uses because of their variableshot size and flow rate characteristics and are adaptable to most applications.

To prepare 1 liter of this solution, dissolve sodium dichromate in 700 ml ofdistilled water. Add sulfuric acid and mix well. Add additional distilled waterto fill to 1 liter. Heat mixed solution to 66 to 71°C (150 to 160°F). Dissolve1.5 grams of 2024 bare aluminum chips per liter of mixed solution. Gentleagitation will help aluminum dissolve in about 24 hours.
To FPL etch panels, place them in the above solution at 150 to 160°F (66 to71°C) for 12 to 15 minutes.
Note: Review and follow precautionary information provided by chemical
suppliers prior to preparation of this etch solution.
