    Formulated to Create Rigid Bonds for Reliable Adhesion
    3M™ Scotch-Weld™ Epoxy Adhesive 2158 is a rigid, multi-purpose, two-part high strength adhesive that chemically cures at room temperature. This equal mix ratio (1:1) epoxy has a 2 hour work life, allowing time for adjustments and positioning of substrates and parts. It reaches handling strength in approximately 10 hours and fully cures in 7 days. With a relatively high viscosity this epoxy (PDF, 19 Kb) dispenses easily to ensure a controlled, precise and accurate application that won't migrate. Once cured this adhesive provides a rigid bond with high shear strength to deliver better dead load holding. This product can be used in a wide range of industries including: general industrial, metalworking, construction, military, transportation and aerospace.

    Recommended Applications
    • General bonding, gluing, joining and attaching
    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 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.
