Product Description
3M™ Scotch-Weld™ Epoxy Adhesive DP460NS is an off-white, non-sag, toughened, two-part structural epoxy adhesive formulated for durable bonding across metals, ceramics, glass, wood, composites and selected plastics. It combines a 2:1 mix ratio by volume with a 60-minute work life, allowing time for adhesive application, joint assembly and repositioning. DP460NS develops handling strength in approximately four hours and reaches full cure in 24 hours at 23°C.
Key features
- Non-sag formulation: Supports controlled adhesive placement on vertical surfaces and assemblies where flow must be limited.
- 60-minute work life: Provides an extended assembly window for positioning and adjustment before cure progresses.
- High shear and peel strength: Provides durable structural bonding with documented overlap shear and T-peel performance.
- Toughened epoxy performance: Supports bonded assemblies exposed to impact, vibration and demanding service conditions.
- Cartridge or bulk supply: Compatible with 3M™ EPX™ dispensing equipment and two-part production dispensing systems.
Suitable for
- Structural bonding of metals and prepared composite materials
- Assemblies requiring extended positioning time and non-sag application
- Bonding ceramics, glass, wood and selected engineering plastics

Additional Information
3M™ Scotch-Weld™ Epoxy Adhesive DP460NS
3M™ Scotch-Weld™ DP460NS is an off-white, non-sag, toughened, two-part epoxy adhesive for demanding structural bonding. Its 60-minute work life provides time for application, positioning and assembly, while the cured adhesive delivers documented shear, peel, electrical and environmental performance across supported substrates.
Non-sag, toughened structural epoxy available in Duo-Pak cartridges and bulk containers.
Key processing properties
DP460NS combines high-viscosity, non-sag rheology with an extended working window. The epoxy base and amine accelerator must be accurately proportioned and thoroughly mixed before application.
| Property | Typical value | Condition and test method |
|---|---|---|
| Base resin (Part B) | Epoxy | - |
| Accelerator resin (Part A) | Amine | - |
| Base viscosity | 150,000–275,000 mPa·s | Approximate at 23°C |
| Accelerator viscosity | 8,000–14,000 mPa·s | Approximate at 23°C |
| Mix ratio by weight, B:A | 2:0.96 | - |
| Color after cure | Off-white | Cured adhesive |
Technical values are representative or typical and must not be interpreted as guaranteed product specifications.
Surface preparation, dispensing and cure
DP460NS may be dispensed from Duo-Pak cartridges using compatible 3M™ EPX™ equipment or proportioned through two-part bulk dispensing systems. Surface condition, proportioning, mixing and joint control materially affect bonded-joint performance.
Recommended visual: cleaning and abrasion, 2:1 dispensing, static mixing, adhesive placement, joint assembly and cure.
Storage and handling
Keep both components in their original packaging and protect them from contamination, excessive heat and direct sunlight. Follow the storage limits and shelf-life information printed on the product packaging and current manufacturer documentation. Review the applicable safety documentation before handling either component.
Shear and peel performance
DP460NS provides documented overlap shear and peel performance across multiple temperatures. Every result remains specific to the stated substrate, surface preparation, cure, bondline geometry and test method.
| Test temperature | Typical value | Context |
|---|---|---|
| −55°C | 33.8 MPa | Etched aluminum; overlap shear |
| 23°C | 32.1 MPa | Etched aluminum; overlap shear |
| 82°C after 15 min | 9.4 MPa | Time in test chamber before testing |
| 82°C after 4 h | 18.5 MPa | Time in test chamber before testing |
| 121°C after 15 min | 2.9 MPa | Time in test chamber before testing |
The reported strength values are laboratory test results and are not universal design allowables. Confirm performance in the intended substrate system, joint geometry and operating environment.
Substrate-specific overlap shear strength
The following typical values were measured at 23°C after seven days using ASTM D1002 or ISO 4587. Results remain specific to the listed substrate, preparation, specimen dimensions, bondline and test rate.
| Substrate | Surface preparation | Value (Psi) | Value (Mpa) |
|---|---|---|---|
| Aluminum | MEK / abrade / MEK | 2,670 psi | 18.4 Mpa |
| Cold rolled steel | MEK / abrade / MEK | 3,600 psi | 24.8 Mpa |
| Stainless steel | MEK / abrade / MEK | 2,400 psi | 16.5 Mpa |
| Copper | MEK / abrade / MEK | 4,400 psi | 30.3 Mpa |
| Brass | MEK / abrade / MEK | 3,400 psi | 23.5 Mpa |
| ABS | IPA wipe / abrade / IPA wipe | 572 psi | 4.0 Mpa |
| Polycarbonate | IPA wipe / abrade / IPA wipe | 390 psi | 2.7 Mpa |
| Acrylic | IPA wipe / abrade / IPA wipe | 270 psi | 1.9 Mpa |
| Fiber-reinforced plastic | IPA wipe / abrade / IPA wipe | 1,379 psi | 9.5 Mpa |
| PVC | IPA wipe / abrade / IPA wipe | 313 psi | 2.15 Mpa |
Specimens used a 25 mm width, 12.7 mm overlap and 0.13–0.20 mm bondline. Separation rate was 2.5 mm/min for metals and 51 mm/min for plastics.
Bell peel and T-peel adhesion
Peel data should be evaluated separately from overlap shear because specimen geometry, peel angle, adherend flexibility and test rate differ.
| Temperature | Typical value |
|---|---|
| −55°C | 19 lb/in width |
| 23°C | 77 lb/in width |
| 82°C | 39 lb/in width |
| Temperature | Typical value |
|---|---|
| −55°C | 3–5 lb/in width |
| 23°C | 60 lb/in width |
| 82°C | 20 lb/in width |
Bell-peel testing used 12.7 mm wide bonds, 1.6 mm bondlines and 15 cm/min jaw separation. T-peel testing used 25 mm wide bonds and 508 mm/min jaw separation.
Physical properties
The following values characterize the cured bulk adhesive. They do not independently establish performance of a complete bonded assembly.
| Property | Test method or condition | Typical value |
|---|---|---|
| Cured color | Visual | Off-white |
| Shore D hardness | ASTM D2240 at 23°C | 81 |
| Flammability classification | Industry specification | UL 94 HB |
Thermal and electrical properties
The cured adhesive provides documented hardness, thermal-expansion and electrical-resistivity properties. These bulk-material results should not be treated as proof of complete assembled-joint performance.
Structural bonding applications
DP460NS is suitable for industrial structural bonding where extended work life, non-sag placement and durable shear and peel performance are important selection factors.
Metal structural assemblies
Documented adhesion data support evaluation on prepared aluminum, steel, copper, brass and stainless-steel substrates.
Composite and engineered-material bonding
The toughened formulation may be evaluated for bonding fiber-reinforced plastics and other supported composite materials after suitable preparation.
Complex or vertical assemblies
Non-sag rheology and a 60-minute work life support controlled placement and extended positioning on larger or more complex assemblies.
