1This represents the oven temperature to which the bonds were subjected for the prescribed time. The average bondline temperature

during the cure time will be somewhat lower than the oven temperature.

2The value in the denominator is the expected minimum 73°F (23°C) T-peel strength (piw) measured after the indicated cure cycle.

NOTE: The data in this Technical Data Sheet were generated using the 3M™ EPX Applicator System equipped with an EPX static mixer,

according to manufacturer’s directions. Thorough hand-mixing will afford comparable results.

Substrates and Testing

A. Overlap Shear (ASTM D 1002-72)

Overlap shear (OLS) strengths were measured on 1 in. wide 1/2 in. overlap specimens. These

bonds were made individually using 1 in. x 4 in. pieces of substrate except for aluminum. Two

panels 0.063 in. thick, 4 in. x 7 in. of 2024T-3 clad aluminum were bonded and cut into 1 in.

wide samples after 24 hours. The thickness of the bondline was 0.005-0.008 in. All

strengths were 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 for

plastics 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

separation rate was 20 inches per minute. The substrates were 0.032 in. thick.

C. Bell Peel (ASTM D 3167)

Bell peel strengths were measured on 1/2 in. wide bonds at the temperatures noted. The

testing jaw separation rate was 6 in. per minute. The bonds are made with 0.064 in. bonded to

0.025 in. thick adherends.

D. Cure 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

aging.

Application

Information

Directions for Use

3M™ Scotch-Weld™ Epoxy Adhesives DP460 Off-White and DP460 NS are

supplied 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

ml configurations. To use the 37 ml cartridge simply insert the duo-pak cartridge

into the EPX applicator and start the plunger into the cylinders using light pressure

on the trigger. Next, remove the duo-pak cartridge cap and expel a small amount of

adhesive to 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 to the duo-pak cartridge and begin dispensing the adhesive.

With the 200 ml and 400 ml cartridges, the nozzle must be attached before

dispensing any material to prevent unmixed adhesive from getting into the

applicator cartridge holder. 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 the

ratio indicated in the typical uncured properties section. Complete mixing of the

two components is required to obtain optimum properties.

Two-part mixing/proportioning/dispensing equipment is available for intermittent

or production line use. These systems are ideal for line uses because of their

variable shot size and flow rate characteristics and are adaptable to most

applications.

Surface Preparation The following surface preparations were used for substrates described in this

Technical Data Sheet.

A. Aluminum Etch

Optimized FPL Etch - 3M (test method C-2803)

1. Alkaline degrease – Oakite 164 solution (9-11 oz./gallon water) at 190°F ±

10°F (88°C ± 5°C) for 10-20 minutes. Rinse immediately in large quantities

of cold running water (3M test method C-2802).

2. Optimized FPL Etch Solution (1 liter):

Material Amount

Distilled Water 700 ml plus balance of liter (see below)

Sodium Dichromate 28 to 67.3 grams

Sulfuric Acid 287.9 to 310.0 grams

Aluminum Chips 1.5 grams/liter of mixed solution

To prepare 1 liter of this solution, dissolve sodium dichromate in 700 ml of

distilled water. Add sulfuric acid and mix well. Add additional distilled water

to fill to 1 liter. Heat mixed solution to 66 to 71°C (150 to 160°F). Dissolve

1.5 grams of 2024 bare aluminum chips per liter of mixed solution. Gentle

agitation will help aluminum dissolve in about 24 hours.

To FPL etch panels, place them in the above solution at 150 to 160°F (66 to

71°C) for 12 to 15 minutes.

Note: Review and follow precautionary information provided by

chemical suppliers prior to preparation of this etch solution.

3. Rinse immediately in large quantities of clear running tap water.

4. Dry – air dry approximately 15 minutes followed by force dry at 140°F

(60°C) maximum for 10 minutes (minimum).

5. Both surface structure and chemistry play a significant role in determining

the strength and permanence of bonded structures. It is therefore advisable

to bond or prime freshly primed clean surfaces as soon as possible after

surface preparation in order to avoid contamination and/or mechanical

damage. Please contact your 3M sales representative for primer

recommendations.

B. Oakite Degrease

Oakite 164 solutions (9-11 oz./gallon of water) at 190°F ± 10°F (88°C ± 5°C) for 2

minutes. Rinse immediately in large quantities of cold running water.

C. MEK/Abrade/MEK

Wipe surface with a methyl ethyl ketone (MEK) soaked swab, abrade and wipe

with a MEK soaked swab.* Allow solvent to evaporate before applying adhesive.

D. Isopropyl Alcohol Wipe

Wipe surface with an isopropyl alcohol soaked swab.* Allow solvent to evaporate

before applying adhesive.

E. Isopropyl Alcohol/Abrade/Isopropyl Alcohol

Wipe surface with an isopropyl alcohol soaked swab, abrade using clean fine grit

abrasives, and wipe with an isopropyl alcohol soaked swab.* Then allow solvent

to evaporate before applying adhesive.

*Note: When using solvents, extinguish all ignition sources, including pilot lights,

and follow the manufacturer’s precautions and directions for use.
