3M™ Scotch-Weld™ Structural Polyurethane Adhesive DP609

3M Scotch-Weld EPX Adhesive DP609 is designed for fast curing at room temperature and delivers strong, durable bonds across a variety of materials. It is particularly effective for bonding plastics as well as painted or primed metal surfaces. With excellent flow from the cartridge and non-sag properties, the adhesive is easy to apply—even on vertical surfaces—while offering reliable gap-filling capability. The product develops handling strength within approximately one hour and continues to build full strength over time, ensuring long-term performance and durability even in demanding conditions and low-temperature environments.
