Scotch-Weld™ Urethane Adhesive
DP605NS, Off-White
Technical Data Sheet September 2016
Product Description 3M™ Scotch-Weld™ Urethane Adhesive DP605NS Off-White is a two-part,
non-sag urethane adhesive. It provides tough, flexible bonds with good
adhesion to a wide variety of substrates, especially wood and many properly
abraded and cleaned plastics. Good adhesion can also be obtained on
painted metals and ceramics and glass. For maximum bond durability under
moisture conditions, priming of glass is required.

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.
B.
Floating Roller Peel (Bell Peel) (ASTM D3167)
Bell peel strengths were measured on 1 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.
C.
Cure Cycle
All bonds were cured 7 days at 73°F (23°C) at 50% RH before testing or
subjected to further conditioning or environmental aging.

3M™ Scotch-Weld™ Urethane Adhesive DP605NS is 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 and 200 ml configurations. 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.
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.
Rinse immediately in large quantities of clear running tap water.
Dry – air dry approximately 15 minutes followed by force dry at 140°F (60°C)
maximum for 10 minutes (minimum).

3. 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 Only Surface Preparation
Wipe surface with an isopropyl alcohol soaked swab.* Allow solvent to
evaporate before applying adhesive.
E.
Isopropyl Alcohol/Abrade/Isopropyl Alcohol Surface Preparation
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.
