Details
Highlights
- Flexible for higher peel strength and better vibration resistance
- Maintains a strong bond under expansion, contraction, and limited movement
- Medium viscosity helps minimize running, dripping, or migration
- 25 minute work life with handling strength in approximately 150 minutes at room temperature
- Flows smoothly for controlled dispensing where needed
3M™ Scotch-Weld Epoxy Adhesive DP125 is a low odor, two-part epoxy that creates strong structural and flexible bonds on metal, ceramics, wood and many plastics. It provides the reliability and strength you need to maintain productive, cost effective results.
Flexible for Higher Peel Strength and Better Vibration Resistance
Our 3M™ Scotch-Weld™ Epoxy Adhesive DP125 is a versatile, medium viscosity, epoxy adhesive that pours easily with minimal dripping, running and migration that will flow smoothly for a controlled, accurate dispensing. Its flexibility makes it ideal for applications involving dissimilar surfaces, where coefficients of thermal expansion are a consideration, for example when bonding glass to metals.
Recommended Applications
General attachment applications in a variety of industries
Replace 5 minute epoxy for improved performance and more positioning time
25 Minute Work Life with Handling Strength in Approximately 150 Minutes
The 1:1 mix ratio for our 3M™ Scotch-Weld™ Epoxy Adhesive DP125 is ideal with bulk mixing and with a 25-minute work life there's some opportunity for repositioning to keep projects on track. The adhesive reaches handling strength in approximately 150 minutes and is fully cured in 7 days (at 72°F/22°C).
Understanding Epoxy Adhesives
Epoxy adhesives are part of the class of adhesives called "structural adhesives," which include polyurethane, acrylic, cyanoacrylate and others. Epoxies are formulated as liquid reactive polymers that undergo a chemical reaction when mixed and then cure to form a solid plastic material. Once the two parts are mixed in their specified ratio, they begin the curing process and offer a limited working time where the adhesive can be applied and the two surfaces positioned as needed. This work life lasts anywhere from a few minutes to several hours. These structural adhesives provide high shear and peel strengths, depending on the formula, and better heat and chemical resistance than other common adhesives. In general, epoxy adhesives have the highest overall strength and offer the best performance and most resistance to high
