Product Introduction
3M™ Scotch-Weld™ Epoxy Adhesive DP421LH is an off-white, toughened, two-part epoxy structural adhesive designed to deliver high peel and shear strength in both high and low temperature environments. It offers exceptional impact and fatigue resistance, making it suitable for a wide range of demanding bonding applications.
This adhesive meets the low halogen requirements defined by the Electrotechnical Commission (IEC) 61249-2-21 Standard, making it well-suited for sensitive electronic and industrial environments. It has a 20-minute work life, providing ample time for positioning and adjusting parts before setting. Curing occurs at room temperature, allowing for easy and convenient application without the need for elevated temperatures.
3M™ Scotch-Weld™ Epoxy Adhesive DP421LH is an excellent alternative to mechanical fasteners, screws, rivets, and spot welds. It also contains a UV tracer, enabling easy automated and visual inspections during and after the bonding process, ensuring consistent quality control in production environments.
