Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive DP420LH is a toughened, two-part epoxy structural adhesive that provides good strength along with high impact and fatigue resistance to meet demanding bonding challenges. This adhesive can replace mechanical fasteners, screws, rivets, and spot welds in many applications, offering high peel and shear strength to maintain a lasting bond at both high and low temperatures. Additionally, it is toughened for enhanced impact and fatigue resistance and features low halogen content.
Try the new 3M™ Scotch-Weld™ Digital Dispensing Assistant and experience shorter machine setup time with this free automation tool for time-pressure systems. This tool enhances adhesive processing results when using Time-Pressure Dispensing Equipment. It ensures the correct amount of adhesive is dispensed, reducing waste and rework. Temperature changes can affect adhesive flow rates and disrupt processing consistency, which can lead to poor bonding outcomes. The 3M™ Scotch-Weld™ Digital Dispensing Assistant, backed by laboratory testing and 3M materials science expertise, simplifies pressure setting predictions.
This tool is free to use and accounts for variables such as temperature, aging, and lot control. After a guided calibration process, users simply enter the adhesive cartridge lot code, current temperature, and desired flow rate. The Digital Dispensing Assistant then provides the recommended pressure setting.
When using dispensing equipment, rely on Bonding and Assembly solutions for convenient and accurate metering, mixing, and dispensing of adhesives.
