3M™ Scotch-Weld™ Structural Plastic Adhesive DP8010 is a blue, 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, corona treatment, or priming. Simply wipe the surfaces with isopropanol to remove mould release agents, dust dirt, etc. 3M™ Scotch-Weld™ Structural Plastic Adhesive DP8010 also bonds metals, ceramics, wood, and most plastics. It is slightly flexible when cured. We also formulate this adhesive with 8 mil (0.20 mm) spacer beads for bond line spacing. Our 3M™ Scotch-Weld™ Structural Plastic Adhesive DP8010 starts with medium viscosity for controlled dispensing and spreads to sufficiently wet out the surface. The mix ratio is 10:1 and provides a 10-minute work life. The adhesive reaches handling strength in approximately 1 hour and is fully cured in 8-24 hours (at 72° F /22° C). Acrylic adhesives are two-part adhesives that provide excellent bond strength and durability. Often referred to as epoxy adhesives or epoxy glue, acrylics actually belong to a separate chemical family with their own unique characteristics. This very unique adhesive bonds LSE plastics without priming or other surface treatments.
