Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive DP420NS WS Black is a toughened, non-sag, two-part epoxy structural adhesive engineered to deliver exceptional strength along with high impact and fatigue resistance for the most demanding bonding challenges. Its non-sag formulation ensures the adhesive stays precisely where it’s applied, even on vertical surfaces, making it clean and easy to use. The adhesive also contains integrated spacer beads to help maintain a consistent bond line thickness for reliable results. With a 20-minute work life, it provides sufficient time for positioning and adjustment. This high-performance epoxy is an excellent alternative to mechanical fasteners, capable of replacing screws, rivets, and spot welds in many applications.
3M™ DP420NS WS Features
- Superior Strength: Provides high peel and shear strength to maintain a lasting bond at both high and low temperatures.
- Toughened Formula: Engineered for excellent impact and fatigue resistance in dynamic applications.
- Practical Work Life: A 20-minute work life provides ample time for positioning and adjustment of parts before curing.
- Non-Sag Formulation: Ensures adhesive stays exactly where applied, preventing drips and runs on vertical or overhead surfaces.
- Controlled Bond Line: Contains spacer beads to ensure a consistent and optimal bond line thickness.
3M™ DP420NS WS Applications
- Replacing mechanical fasteners such as screws, rivets, and spot welds for a cleaner aesthetic and better stress distribution.
- Structural bonding in applications requiring high peel and shear strength.
- Bonding tasks where superior impact and fatigue resistance are critical.
- Vertical or overhead bonding where a non-sag adhesive is essential.
- Applications that require precise control of the final bond line thickness.
