When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.Works Efficiently for Large Structure BondingUnlike using screws or rivets, our 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.Recommended ApplicationsHoneycomb panels in rail cars, elevators, and aircraftDelivery truck side walls and flooringMetal enclosure facing and cabinetsPanels or screens to framesOther large surface bonding applications that require long open timesDesigned for Bulk ApplicationThis 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 73F (23C).The mix ratio is 1:1 and provides a 90 minute work life, providing ample time to adjust for desired fit prior to curing. Our 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 AdhesivesEpoxy 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 temperatures, solvents and outdoor weathering.Epoxy adhesive (often referred to as epoxy glue) is 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. It is 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 epoxy for plastic flexible or epoxy for metal rigid, epoxy resin transparent or opaque, quick setting or slow setting. The versatility with which these adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone and various plastics.
