Description
3M™ Scotch-Weld™ Epoxy Adhesive DP420NS is a two-part, toughened structural epoxy that provides exceptional strength, durability, and impact resistance across a wide variety of substrates, including metals, composites, ceramics, and many plastics. Its non-sag formula allows precise, clean application on vertical or overhead surfaces without dripping .
This adhesive offers high shear and peel strength, maintaining performance under vibration, dynamic loads, and temperature cycling. It cures at room temperature and can be accelerated with heat for faster production throughput. Once cured, it forms strong, fatigue-resistant bonds that stand up to moisture, heat, and harsh environmental exposure.
Benefits:
- High shear and peel strength
- Bonds metals, composites, and plastics
- Non-sag for clean vertical application
- Excellent impact and fatigue resistance
- Outstanding durability in extreme conditions
Key Features:
- Non-sag formulation for precise vertical bonding
- High toughness and durability under vibration and impact
- Bonds dissimilar materials — metals, composites, plastics, ceramics
- Excellent environmental resistance to moisture, heat, and fatigue
- Easy 2:1 mix ratio, compatible with 3M™ EPX™ applicators
- Room temperature cure, optional heat acceleration for faster results
