3M DP460 Epoxy Adhesive: High-Strength Industrial Bonding Solution
Basic Product Properties
3M DP460 is a gray-white two-part epoxy structural adhesive (A:B volume ratio 2:1) with a 60-minute work life (24°C). It achieves a shear strength of 4500 PSI after 24-hour room-temperature curing. Suitable for metals, plastics, carbon fiber, etc., with a service temperature range of -55°C to 121°C. Compliant with MIL-A-23941A military standard and UL-HB certification
Product Overview
DP460 delivers exceptional impact resistance and fatigue resistance through a toughened formula, maintaining stable bonds in vibrating, humid, or chemically corrosive environments. Non-polluting, non-whitening, and low-odor after curing, meeting eco-standards (GB 33372-2020 VOC limits). Its "non-sag" property (DP460NS variant) prevents displacement on vertical surfaces, requiring dedicated EPX applicators and mixing nozzles for uniform mixing
Advanced Technical Features
- High Strength & Durability: Shear strength remains 4500 PSI from -55°C to 24°C, and 700 PSI at 82°C; room-temperature peel strength 60 PIW for permanent structural bonds.
- Environmental Resistance: Bonds directly to lightly oil-contaminated metals (no pretreatment); resistant to acids, alkalis, solvents, and long-term water immersion.
- Processing Advantages: 60-minute work life enables complex positioning; reaches handling strength in 2–4 hours and full cure in 24 hours at room temperature. Dual-cartridge packaging (50ml/400ml) supports manual or automated dispensing
Application Scenarios
Sports Equipment: Carbon fiber bicycle frames (metal-CF bonding for weight reduction), skis, golf clubs (high impact resistance).
Transportation: High-speed train coupling parts, automotive panels (replacing rivets/welding; DP460NS for vertical bonding).
Aerospace: Aircraft fuel tank sealing (resists -55°C), spacecraft electronics bonding (insulation & radiation resistance).
Industrial Machinery: Motor rotor magnet bonding (4500 PSI shear strength prevents detachment), structural reinforcement (concrete-metal bonding)
