Main features
- Flexible Dissimilar Material Bonding
- Controlled Non Sag Dispensing
- Extended Panel Assembly Window
Product Description
3M Scotch-Weld Flexible Acrylic Adhesive DP8625NS is a black, low-odor, non-flammable acrylic structural adhesive supplied in a 10:1 cartridge system for static-mixer dispensing. The non-sag paste holds its shape in vertical joints, panel seams, and gaps between steel, aluminum, composites, and selected plastics. A 21 minute open time provides a defined positioning window, and handling strength develops in approximately 28 minutes at 23 deg C. After seven days, the cured adhesive reaches 200% elongation and Shore D 35 hardness for flexible dissimilar-material assemblies.
Key features
- Flexible Dissimilar Material Bonding: The cured acrylic supports compatible metal, composite, and plastic assemblies.
- Non Sag Cartridge Dispensing: The 10:1 paste formulation controls placement through a static mixer.
- Extended Assembly Window: A 21 minute open time supports positioning before parts are fixed.
Applications
Panel-to-frame bonding, thin-panel assembly, dissimilar-material joining, and controlled gap filling with compatible substrates.
