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.
When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.
Used in large structure bonding for aluminum 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.

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 73°F (23°C).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, 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 temperatures, solvents and outdoor weathering.
Epoxy adhesives are widely used in building and home construction; aircraft and automobile manufacturing; bicycle, boat, golf clubs, ski and snowboard assembly as well as a host of home use and other applications. They are used virtually anywhere high-strength bonds are needed along with resistance to environmental conditions. These adhesives are popular for their ease of use, mechanical strength and chemical resistance. Formulations can be created to make epoxies flexible or rigid, transparent or opaque, quick setting or slow setting. The versatility with which epoxy adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone and various plastics.
Industrial uses for epoxies range widely and, in addition to adhesives, include coatings and composite materials like carbon fiber and glass-reinforced composites. They are the preferred choice due to their ability to flow and conform to the work area, strong adhesion, chemical and heat resistance and exceptional mechanical and electrical insulating properties.
