3M DP8610NS
Harmonization Code : 3907.30.00.40 | Epoxy Mold Compounds containing by weight more than 70 % silicon dioxide
Main features
- Flexible Dissimilar Material Bonding
- Non Sag Bondline Control
- Fast Handling Strength Development
Product Description
3M Scotch-Weld Flexible Acrylic Adhesive DP8610NS is a black, low-odor, non-flammable two-part acrylic structural adhesive with a 10:1 mix ratio. The non-sag formulation and internal spacer beads support controlled bondline placement on panels, frames, thin materials, and dissimilar substrates. A 7 minute work life and 20 minute handling-strength time support fast room-temperature assembly. After cure, the flexible adhesive provides 140% elongation and qualified overlap-shear performance across metals, plastics, and fiber-reinforced composites for efficient industrial panel assembly.
Key features
- Flexible Dissimilar Material Bonding: The acrylic system bonds compatible metals, plastics, and composite panels.
- Non Sag Bondline Control: Thixotropic flow and spacer beads support consistent adhesive placement.
- Fast Handling Strength Development: The mixed adhesive reaches handling strength in about 20 minutes at 23 deg C.
Applications
Panel and frame bonding, thin-panel assembly, and joining compatible dissimilar substrates in transportation and industrial structures.
