3M 7100148768 Scotch-Weld™ Epoxy Adhesive DP460, Off-White, 50 mL Duo-Pak
3M Scotch-Weld™ Epoxy Adhesive DP460, Off-White, 50 mL Duo-Pak
The 3M Scotch-Weld DP460 is a toughened, two-part structural epoxy adhesive formulated for high-impact and high-stress bonding applications where standard epoxies would crack or delaminate. Mixed at a 2:1 ratio, it delivers 4,500 psi lap shear strength, 60–90 minutes of working time, and handling strength in approximately 4 hours — with full cure in 24 hours at 73°F. The DP460 bonds to metals, ceramics, glass, wood, and many plastics, and meets UL 94 HB, ASTM E662, and Bombardier SMP 800-C specifications. This listing is for the 50 mL Duo-Pak cartridge (part number 7100148768), which is compatible with 3M EPX Plus II applicators and standard static mixing tips.

Frequently Asked Questions
What makes the DP460 a "toughened" epoxy — and when does that matter?
Standard epoxies cure to a rigid, brittle polymer that can crack under impact or vibration. The DP460 is formulated with toughening agents that allow the cured adhesive to absorb impact energy and flex slightly before failing, making it the right choice for assemblies subject to shock, vibration, or thermal cycling — such as transportation components, electronics enclosures, and structural joints in demanding environments.
What dispensing equipment is required for the 50 mL Duo-Pak?
The 50 mL Duo-Pak cartridge is designed for use with the 3M EPX Plus II manual applicator gun. Static mixing tips (sold separately) attach to the cartridge nozzle and automatically meter and mix the 2:1 ratio as the adhesive is dispensed. This eliminates manual mixing errors and ensures consistent mix ratio throughout the cartridge. Contact MTE Solutions for compatible applicator and tip part numbers.
How does the DP460 compare to the 3M DP420 or DP190?
The DP460 is optimized for high-impact and peel-resistant applications with a 60–90 minute work life. The DP420 is a higher-strength, lower-toughness epoxy better suited for rigid structural bonds where impact resistance is less critical. The DP190 is a faster-curing translucent epoxy for general-purpose bonding. Choose the DP460 when the joint will experience shock, vibration, or dynamic loading.
Can the DP460 be used on plastics?
The DP460 bonds to many plastics, but adhesion varies significantly by plastic type and surface energy. High-surface-energy plastics (ABS, polycarbonate, nylon, acrylic) bond well with proper surface preparation. Low-surface-energy plastics (polyethylene, polypropylene, PTFE) require surface treatment (flame, plasma, or primer) for adequate adhesion. Always test on the specific substrate before production use.
