3M™ Scotch-Weld Epoxy Adhesive 100 Plus is a very flexible, fast-setting, two-part epoxy adhesive that dries clear and stays clear even when cured in larger masses. This epoxy stays clear, but not colorless when cured in large masses.
Very flexible adhesive formula provides strong, permanent bond even under vibration and impact
Provides high shear and peel strength
Expands and contracts under changing environmental conditions
Provides handling strength in approximately 15 minutes at room temperature
Flexible when cured, making it a good choice for bonding dissimilar surfaces
There's no more versatile structural epoxy than our 3M™ Scotch-Weld Epoxy Adhesive 100 Plus. It works on a variety of substrates including metals, ceramics and glass, wood, and many plastics. The low viscosity makes it easy to dispense and self-level; and an effective tool for filleting and potting. It features high shear strength and good peel performance that, when combined with good flexibility, make it ideal for a variety of applications in the transportation, specialty vehicle, electrical, general industrial, sporting goods, construction, and consumer goods industries.

The mix ratio is 1:1 for quick, precise dispensing, and with a three- to five-minute working time there's some opportunity for repositioning to keep projects on track. The adhesive reaches handling strength in approximately 20 minutes and is fully cured in 48 hours (at 72°F/22°C). This product is available in bulk or smaller Duo-Pak cartridges.
Structurally Strong, What are Epoxies?
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 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.
