Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive DP420LH is a toughened, two-part epoxy structural adhesive formulated for demanding bonding challenges. It provides good strength combined with high impact and fatigue resistance, making it an excellent replacement for mechanical fasteners like screws, rivets, and spot welds. This adhesive maintains high peel and shear strength for a lasting bond across both high and low temperatures. It is also formulated with low halogen content for compliance with specific industry requirements.
3M™ DP420LH Features:
- Delivers high peel and shear strength for a lasting bond at high and low temperatures.
- Toughened formulation provides superior impact and fatigue resistance.
- Low halogen content meets specific electronic and industrial regulations.
- Can be used with the 3M™ Scotch-Weld™ Digital Dispensing Assistant for shorter machine setup time.
3M™ DP420LH Applications:
- Replacing mechanical fasteners, screws, rivets, and spot welds in structural assemblies.
- Bonding processes in applications requiring high impact and fatigue resistance.
- Structural bonding in transportation, aerospace, and general industrial environments.
- Use with automated time-pressure dispensing equipment for high-volume production.
