3M Scotch-Weld DP6310 Green Multi-Material Composite Urethane Adhesive (48.5ml Duo-Pak)
📌 Product Overview
The 3M Scotch-Weld DP6310 (often designated as DP6310NS) is a premium, high-performance, two-part structural polyurethane adhesive. Specifically engineered for multi-material and composite assemblies, this adhesive delivers exceptional structural strength combined with enough flexibility to handle the thermal expansion and contraction differences when bonding dissimilar materials.
Its non-sag, thick paste formulation resists running and slumping, making it absolutely ideal for precise applications on contoured, vertical, or overhead surfaces. In many manufacturing and repair environments, DP6310 successfully replaces rivets, screws, and mechanical fasteners to yield a cleaner, more fatigue-resistant bond line.
🛠️ Where Can It Be Used? (Target Applications)
This versatile structural glue is highly favoured across the Transportation, Automotive, Aerospace, Sporting Goods, and Marine Repair industries.
Primary Materials It Bonds:
- Composites: Carbon Fiber (CFRP), Fiberglass (GRP), and epoxy-based laminates.
- Plastics: Most structural plastics (excluding low surface energy plastics like PE/PP unless pre-treated).
- Metals: Steel, Aluminium, Stainless Steel, and galvanized surfaces (Primerless on most metals!).Natural Materials: Wood, concrete, tile, and glass.
Common Use Cases:
- Automotive & Marine: Bonding composite body panels to metal frames, attaching carbon fiber spoilers/trim, and joining interior panels.
- Specialty Vehicles: Panel-to-post bonding in trailers, vans, and ambulances.
- Sporting Goods: Repairing composite bicycle frames, carbon fiber hockey sticks, oars, and golf clubs.
- Industrial Assemblies: Assembling display structures, sign-making, and structural multi-material brackets.
