A. Overlap Shear (ASTM D1002)

Overlap Shear (ASTM D-1002-64, 3M Test Method C-236) strength was

measured on 1" wide x 1/2" overlap specimen. These bonds were made

individually using 1" x 4" pieces of substrates except for Aluminum. Two

panels 0.063 in. thick, 4 in. x 7y in of 2024T-3 clad aluminum were

bonded and cut into 1 in. wide samples after 24 hours. The thickness of the

adhesive bond line was approximately 0.005". All strengths were

measured at 73°F (23°C) except when 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,

0.125in.; plastics, 0.125 in. and samples were allowed to cure at 75°F (24°C)

and approximately 50% RH for 1 week before tested. The separation rate of the

testing jaws was 0.1 inch per minute for metals and 2 inches per minute for

plastics.

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 were made with 0.064 in. bonded to 0.025 in. thick adherends.

All bonds were cured 7 days at 73°F (23°C) at 50% RH before testing or

subjected to further conditioning or environmental aging.

Directions for Use

3M™ Scotch-Weld™ Urethane Adhesives DP600 Self-Leveling and DP600NS are

supplied in dual syringe plastic duo-pak cartridges as part of the 3M™ EPX™

Applicator System. The duo-pak cartridges are supplied in 50 ml configuration. To

use the EPX cartridge system simply insert the duo-pak cartridge into the EPX

applicator. 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.

When mixing Part A and Part B manually the components must be mixed in the

ratio indicated in the typical uncured properties section of this data sheet.

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.

Apply adhesive to clean, dry surfaces, joint parts and secure until adhesive sets.
