3M Scotch-Weld Epoxy Adhesive DP100 Plus Clear, 1.69 oz (Pack of 1)
3M™ Scotch-Weld™ Epoxy Adhesive DP100 Plus Clear is a general purpose, two-part epoxy adhesive that sets fast and bonds to a wide variety of substrates including metals, ceramics, wood, and many plastics. It is unique among fast setting mercaptan-cure epoxies in that it combines high shear strength with good peel performance properties. Mercaptans cure epoxies rapidly at ambient temperatures, are light in color, and contribute toward strong adhesion. DP100 Plus Clear is transparent and slightly flexible when cured. This clear drying, general purpose epoxy starts with low viscosity for good flow that provides easy, controlled dispensing. The mix ratio is 1:1 and provides a 3-5 minute work life. The adhesive reaches handling strength in approximately 20 minutes and is fully cured in 24-48 hours (at 720F/220C). DP100 Plus dries clear to provide clean surfaces, free from fasteners, nails, and welds. Both mixing nozzle and applicator are required for dispensing from the Duo-Pak cartridge and are sold separately. For best results, always use 3M™ Scotch-Weld™ EPX™ Plus II Applicator and Mixing Nozzles.Product InformationKey FeaturesMix Ratio (Volume) B:AApproximate Viscosity 75°F/24°C (cps)Approximate Mixed Worklife at 75°F/24°CApproximate Time to Handling Strength at 75°F/24°CAverage T-Peel at 75°F/24°C (piw)Overlap Shear (psi)Very flexible Colorless1:18,5004 Minutes20 Minutes1030003,500200What Are Epoxy Adhesives?Epoxies are polymeric materials that start out as liquids and undergo a chemical reaction to form a solid. These compounds are a major part of the class of adhesives called "structural adhesives," which includes polyurethane, acrylic, cyanoacrylate, and others. Epoxies include two compounds: resins and hardeners. When the two are mixed in their specified ratio they react chemically; and once the reaction has finished, they form a strong and rigid plastic material. Once the two parts are mixed, there is a limited working time in which the epoxy can be applied, ranging from a few minutes to an hour or longer. These adhesives provide better heat and chemical resistance than other common adhesives and those that require heat to cure will be more heat and chemical resistant than those that cure at room temperature. An epoxy based polymer is mechanically strong, chemically resistant to degradation, and very tacky during its working time. Epoxy adhesives are used in the manufacture of buildings, homes, aircraft, automobiles, bicycles, boats, golf clubs, skis, and snowboards, as well as many other applications where high-strength bonds are needed along with resistance to environmental conditions. Epoxy adhesives can be formulated to meet almost any requirement for bonding wood, metal, glass, stone, and various plastics. Using different formulations, epoxies can be made flexible or rigid, transparent or opaque, quick setting or slow setting.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.About 3M Industrial Adhesives and TapesFor more than a century, 3M has applied innovation and technology to improving our customers’ lives and supporting their business goals.
