3M™ Scotch-Weld™ DP490 is a two-component structural epoxy adhesive designed for demanding industrial bonding applications requiring high mechanical strength, long-term durability, and resistance to fatigue and environmental stress.
It enables permanent structural bonding of metals, composites, and many rigid substrates where mechanical fastenings or welding are not practical.
The adhesive offers an excellent balance of stiffness and toughness, supporting industrial assemblies subjected to vibration, dynamic loads, and thermal stress over time.
This black, thixotropic, and sag-resistant adhesive is ideal for high-throughput industrial processes and mass production.
3M™ DP490 adhesive is recommended for technical buyers in:
- OEM manufacturing and industrial production lines
- Metal fabrication and structural assembly
- Composite manufacturing and lightweight engineering
- Transportation equipment and vehicle components
- Electrical enclosures and industrial machinery
- Maintenance, repair and overhaul (MRO) operations
Ideal when you need:
- High-strength structural bonding of metals and composites
- Long-term fatigue and vibration resistance
- Extended working time for complex assemblies
- Permanent structural joints without mechanical fasteners
- Improved load distribution across bonded surfaces
- Reliable performance in demanding industrial environments
Suitable for professional industrial supply, supporting OEM manufacturing, engineering workshops and industrial assembly operations.

Frequently Asked Questions (FAQ)
Q: What temperature can DP490 withstand?
A: It offers high temperature resistance up to about 120 °C (248 °F) in service.
Q: What does “thixotropic / non‑sag” mean here?
A: The adhesive is thixotropic, so it stays where applied and is suitable for vertical and overhead joints without running.
Q: How long does it take to cure?
A: It cures at room temperature; full structural strength is typically reached after 24 hours (often with handling strength earlier), and cure can be accelerated with heat.
