Details
Highlights
- Toughened for heightened resistance against shock, vibration, and impact loads
- 90 minute work life provides ample time for positioning and adjustment
- Features good long-term holding power, and high peel strength
- Delivers non-sag formulation so adhesive stays where applied
- Ideal for bulk application through meter mix dispensing equipment
3M™ Scotch-Weld™ Toughened Epoxy Adhesive LSB60NS is a gray, high performance, non-sag, two-part toughened epoxy adhesive that offers good shear adhesion and high durability. With a 90 minute work life and 1:1 mix ratio, this epoxy adhesive is often used for bulk application through meter mix dispensing equipment and the manufacture of large panel products including honeycomb panels.
Works Efficiently for Large Structure Bonding
Unlike using screws or rivets, 3M™ Scotch-Weld™ Toughened Epoxy Adhesive LSB60NS lets you distribute stress uniformly over the entire bonded area while maintaining surface integrity and the physical properties of the panel. It allows you to use thinner, lighter panel materials without worrying about distortion, splitting, or crazing and will secure even small or thin bonding edges. Offering high resistance against shock and vibration, it features good shear and peel adhesion with high levels of durability.
Recommended Applications
Delivery truck side walls
Metal enclosure facing and cabinets
Panels to frame
90 Minute Work Life Provides Ample Time for Positioning and Adjustment
This epoxy dispenses as a medium viscosity adhesive for easy, controlled dispensing. The adhesive reaches handling strength in approximately 6 hours and is fully cured in 7 days at 73ºF (23ºC).The mix ratio is 1:1 and provides a 90 minute work life, providing ample time to adjust for desired fit prior to curing. 3M™ Scotch-Weld ™ Toughened Epoxy Adhesive LSB60NS is ideal for bulk application through meter mix dispensing equipment and the manufacture of large panel products.
Understanding Epoxy Adhesives
Epoxy adhesives are part of the class of adhesives called "structural adhesives," which also includes 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,
