3M™ Scotch-Weld™ Structural Plastic Adhesive DP8005 Black 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 Black 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 Black 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.
Creates strong bond on low surface energy plastics (LSE) such as polyolefin with minimal or no surface prep required
Resists many chemicals, water, humidity and corrosion
Formulated to bond multi-material assemblies such as LSE plastics, thermoplastics composites and metals
Medium viscosity allows controlled dispensing
3 minute work life with 3 hours handling strength
Strong adhesive can replace screws, rivets and welding
