3M DP760 Scotch Weld Epoxy Adhesive high temperature - 50 ml cartridge

3M™ Scotch-Weld™ DP760: high-temperature epoxy structural adhesive

3M™ Scotch-Weld™ DP760 is a two-component epoxy structural adhesive developed for applications requiring high resistance to elevated temperatures. It cures at room temperature to form a rigid, durable bond and is particularly suitable for demanding metal-bonding applications where conventional adhesive systems may not meet the required thermal performance.

Its non-sag paste consistency helps keep the adhesive in place during application, including on vertical surfaces. The 45–60-minute open time at room temperature provides time to position components and assemble larger parts. DP760 is supplied in a 50 ml cartridge and uses a 2:1 mix ratio by volume.

Which Materials Can 3M DP760 Bond?

3M DP760 is designed for bonding a range of substrates, including metals, wood, fibre, reinforced plastics and glass. The suitability of the adhesive depends on the exact substrate, surface preparation, operating temperature and mechanical loads.

For critical or production applications, test the adhesive on the actual materials before implementation. Not every grade of metal, plastic or glass will behave identically, and the maximum temperature rating alone does not establish suitability for every joint design.

Key Industrial Performance Advantages

• High-temperature resistance: designed for applications requiring resistance to temperatures up to 230 °C.
• Rigid structural bond: cures to form a hard, durable adhesive joint.
• Two-component epoxy system: the base and accelerator are mixed at the specified ratio to initiate curing.
• Non-sag formulation: the paste consistency helps prevent the adhesive from flowing away from the application area.
• Extended open time: approximately 45–60 minutes at room temperature, providing time to position components.
• Handling strength: typically reached in approximately 4–6 hours under the manufacturer's specified conditions.

Industrial Applications of 3M DP760

High-temperature metal bonding

DP760 is particularly relevant when metal components must be bonded in applications exposed to elevated temperatures. It is worth evaluating for assemblies where a rigid adhesive joint and thermal resistance are important design criteria.

Industrial equipment and machinery

The adhesive can be considered for compatible structural bonding tasks in industrial equipment, machinery and fabricated assemblies. The joint must be designed for the actual loads, temperature cycles and environmental conditions of the equipment.

Components exposed to heat

DP760 is designed for applications in which thermal exposure is a primary adhesive-selection criterion. Before use, verify both the expected service temperature and the duration of exposure against the current technical data sheet and application requirements.

Assembly and maintenance

The non-sag paste and extended open time can be useful when assembling components that require careful positioning before the adhesive begins to set. 

How to Use 3M DP760

1. Prepare the surfaces: clean the substrates and remove contaminants that could interfere with adhesion. Follow the recommended preparation procedure for the specific materials.
2. Check the dispensing system: use a compatible 3M EPX dispensing system and mixing nozzle appropriate for the cartridge.(Manual applicator for 50 ml two-component cartridges, 1:1 and 2:1 mixing nozzle, 48.5 ml and 50 ml)
3. Maintain the correct mix ratio: DP760 uses a 2:1 ratio by volume. Use the specified dispensing system to deliver and mix the components correctly.
4. Apply the adhesive: dispense enough material to create the intended joint, following the joint design and application requirements.
5. Position the components: assemble the parts within the available open time, which is approximately 45–60 minutes at room temperature under the specified conditions.
6. Keep the assembly stable: hold or fixture the components as necessary while the adhesive cures. Handling strength is typically reached in approximately 4–6 hours; this does not necessarily mean full cure has been achieved.
7. Verify the bond before service: follow the manufacturer's curing instructions and confirm that the joint is suitable for its intended mechanical and thermal loads. Actual working and curing times may vary depending on temperature, the quantity mixed, and application conditions.

3M DP760 vs DP460: Which Epoxy Should You Choose?

3M DP760 and 3M DP460 are two-component epoxy structural adhesives, but the selection should be based on the application's main requirements rather than on a general assumption that one product is stronger than the other.

Which one should you choose? Consider DP760 when high-temperature resistance is a central requirement, particularly for suitable metal-bonding applications. Consider DP460 when its specific structural performance characteristics better suit the design. For either product, compare the current technical data sheets, including strength at the relevant temperature, curing conditions, substrates and joint design, before making a final selection.

Technical Specifications of 3M DP760

Frequently Asked Questions About 3M DP760

What is the maximum temperature resistance of 3M DP760?

3M specifies temperature resistance up to 230 °C. Actual joint performance at elevated temperatures depends on the substrate, applied load, exposure duration, joint geometry and curing conditions.

Is 3M DP760 suitable for bonding metal?

Yes. 3M identifies metals as suitable substrates and highlights high-temperature metal bonding as an important application. Surface preparation and compatibility should be verified for the specific metal grade.

How long is the open time of 3M DP760?

The stated open time is approximately 45–60 minutes at room temperature. Actual working time can vary with temperature, mixed quantity and application conditions.

Does 3M DP760 cure at room temperature?

Yes. DP760 is designed to cure at room temperature. Follow the technical data sheet for the applicable curing conditions and any additional requirements for the intended application.

What is the difference between 3M DP760 and DP460?

DP760 is specifically designed for applications requiring high-temperature resistance. DP460 should be evaluated against its own documented mechanical and environmental properties. The best choice depends on the substrates, operating temperature, loads and curing requirements.

Which dispensing equipment is required for 3M DP760?

Use a compatible 3M EPX dispensing system and the correct mixing nozzle for the cartridge. Verify equipment compatibility and the manufacturer's instructions before dispensing.
