• Formula is ideal for potting and bonding electronic and electrical components.
• Non exothermic reaction safeguards heat-sensitive components.
• Extended work time allows for positioning and adjustment to fit prior to setting.
• Non corrosiveness to copper preserves conductivity and retention of insulation properties.
• Effective adhesive system for potting, bonding, joining, gluing, attaching, assembling, encapsulating, and sealing applications.

From the Manufacturer --------------------- 3M™ Scotch-Weld™ Epoxy Potting Compound DP270 Clear is a two-part, low viscosity, self leveling epoxy resin system designed primarily for potting, sealing, and encapsulation of many electronic components. It is non-corrosive to copper, non-exothermic and its low viscosity provides high flow rate, ideal for precise control when dispensing small as. It dries to a clear, amber color with very little shrinkage and its clarity allows visibility of the component. DP270 also protects the component from moisture and contaminants and is suitable for outdoor use. This adhesive provides structural strength and also bonds a wide variety of substrates including metals, ceramics, wood, and many plastics. This clear drying adhesive and potting compound begins with low viscosity for easy, controlled dispensing. The mix ratio is 1:1 and provides a 60 minute work life, which allows plenty of time to position and to adjust fit prior to setting. The adhesive reaches handling strength in approximately 3 hours and is fully cured in 48 hours (at 720F/220C). DP270 meets the requirements of UL 94 HB (Horizontal Burn). 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.

Epoxies are polymeric materials that start out as liquids and undergo a 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 ly; 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 resistance than other common adhesives and those that require heat to cure will be more heat and resistant than those that cure at room temperature. An epoxy based polymer is mechanically strong, ly 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, and heat resistance, and exceptional mechanical and electrical insulating properties.
