3M Scotch-Weld Epoxy Adhesive DP105 Clear, 1.7 oz (Pack of 1)
3M™ Scotch-Weld™ Epoxy Adhesive DP105 Clear is a very flexible, two-part epoxy adhesive that is effective for glass to metal bonding and sealing. It provides structural strength and bonds on a wide variety of substrates including metals, ceramics, wood, and many plastics. This clear drying, general purpose epoxy begins with low viscosity for easy, controlled dispensing. DP105 Clear provides 100% elongation when cured, making it ideal for applications involving dissimilar surfaces, where coefficients of thermal expansion is a factor. This adhesive also provides the benefit of retaining its clear, colorless properties even when cured in larger quantity, where many clear epoxy systems often turn amber from the exothermic reaction. The mix ratio is 1:1 and provides a 5 minute work life. The adhesive reaches handling strength in approximately 20 minutes and is fully cured in 48 hours (at 720F/220 C). 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 Colorless1:16,5005 Minutes20 Minutes353,5002,000150What 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.
