Scotch-Weld 92166 DP8005 Series Structural Plastic Adhesive, 35 mL Cartridge, Paste, White/Black, 24 hr Curing

3M™ Scotch-Weld™ structural plastic adhesive DP8005 is a two-part acrylic adhesive specially formulated to bond many low surface energy plastics, including many-grades of polypropylene, polyethylene and thermoplastic elastomers (TPEs) without special surface preparation. Structural bonds can be achieved without special surface treatments such as chemical etching, plasma, flame or corona treatment or priming. Simply wipe the surfaces with isopropanol to remove mold release agents, dust dirt, and more. 3M™ Scotch-Weld™ structural plastic adhesive DP8005 bonds metals, ceramics and wood and most other plastics. We also formulate this adhesive with 8 mil spacer beads for bond line spacing. Our 3M™ Scotch-Weld™ acrylic adhesive DP8005 starts with medium viscosity for controlled dispensing and spreads to sufficiently wet out the surface. The mix ratio is 10:1 and provides a 3 min work life. The adhesive reaches handling strength in approximately 3 hr and is fully cured in 24 hr (at 72 deg F/22 deg C).
