Highlights
  • 3 minute work life
  • Structurally bonds polyolefins without surface treatment
  • Medium viscosity
  • Choose for easy mixing and dispensing, medium viscosity, rigid bonds and more|| One step process results in a strong bond on low surface energy plastics minimizing or eliminating pre-treatment or preparation of the substrates needed prior to bonding
  • 3 minute work life with 3 hours handling strength
  • Strong adhesive can replace screws, rivets and welding

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.

When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.

Creates a Strong Bond on Low Surface Energy Plastics
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, etc. 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.

Recommended Applications

  • Joining plastics to metals, such as in the manufacture or repair of appliances
  • Bonding low surface energy plastics without priming
  • Impact resistance composite bonding
  • Manufacture or repair of various sporting goods equipment
  • Low surface energy plastics such as polypropylene, polyethylene and thermoplastic elastomers (TPEs)

Medium Viscosity Allows Controlled Dispensing
Our 3M™ Scotch-Weld™ Structural Plastic 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 minute work life. The adhesive reaches handling strength in approximately 3 hour and is fully cured in 24 hours (at 72° F/22° C).

Easy Adhesion with Acrylic
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.
