3M™ Scotch-Weld™ Toughened Epoxy Adhesive LSB60 is a high performance, two-part toughened epoxy adhesive that offers outstanding shear adhesion and very 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.
Toughened for high resistance against shock, vibration, and impact loads
90 minute work life provides ample time for positioning and adjustment for fit
Features great long-term holding power, and high peel strength
Medium viscosity, self-leveling formula provides easy, precise dispensing
Ideal for bulk application through meter mix dispensing equipment
Works Efficiently for Large Structure Bonding
Unlike using screws or rivets, 3M™ Scotch-Weld™ Toughened Epoxy Adhesive LSB60 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 outstanding shear and peel adhesion with very high levels of durability.

Designed for Bulk Application
This epoxy dispenses as a medium viscosity adhesive for easy, controlled dispensing. The adhesive reaches handling strength in approximately 5 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 LSB60 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 begin as liquid reactive polymers that undergo a chemical chain 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 need. This "work life" lasts anywhere from a few minutes to 48 hours or longer. This class of structural adhesives provides high shear and peel strengths, depending on the formula and better heat and chemical resistance than other common adhesives. Epoxies that are heat cured are more heat and chemical resistant than those that cure at room temperature.
Epoxy adhesives are widely used in building and home construction, aircraft and automobile manufacture, bicycle, boat, golf clubs, ski, and snowboard assembly and a host of home use and other applications; 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 that are 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 include coatings, adhesives, and composite materials like carbon fiber and glass-reinforced plastic. They are the preferred choice for their ability to flow and conform to the work area, strong adhesion, chemical and heat resistance, and exceptional mechanical and electrical insulating properties.
