3M™ Scotch-Weld™ Epoxy Adhesive 3501 is thixotropic which allows for controlled flow and easy dispensing. We engineered our Scotch-Weld™ Epoxy Adhesive 3501 to also offer high viscosity for accurate positioning and application. Formulated as an easy 1:1 mix ratio, our Scotch-Weld™ Epoxy Adhesive 3501 has a 6-10 minute work life and reaches handling strength in approximately 25 minutes. This particular epoxy adhesive is fast-curing at room temperature and reaches full cure in 48 hours.
3M™ Scotch-Weld™ Epoxy Adhesive 3501 can be utilized in multiple industries, including sporting goods, solar energy, wind energy, composites, electronics, military, transportation and aerospace.
Some of the recommended applications of this epoxy adhesive include the following:
Explaining 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.
