3M™ Scotch-Weld Epoxy Adhesive 2216NS, Tan, Part B, 5 Gallon (Pail), Drum

Product Description

Scotch-Weld Epoxy Adhesive 2216NS

• COLOR: Tan
• FAST HEAT CURING: Fully cured in 30 minutes at 200 °F (93 °C)
• LONG-LASTING STRENGTH: Withstands the impact of expansion and contraction
• MANY SUBSTRATES: Aluminum and other metals, wood, glass, stone, and various plastics
• NON-SAG FORMULA: Made to apply accurately and with precision for greater bond line control
• OPPORTUNITY TO ADJUST: Allows up to 120 minutes of working time
• VERSATILE APPLICATIONS: Bonds metals and other substrates in construction, specialty vehicle, among many others

When using a Duo-Pak (DP) size adhesive, rely on 3M dispensing equipment for convenient and accurate metering, mixing and dispensing.

Non-Sag Properties Provides Greater Bond Line Control
3M™ Scotch-Weld Epoxy Adhesive 2216NS is a non-sag version of the 3M™ Scotch-Weld Epoxy Adhesive 2216. It is designed for applications where high performance and flexible bonds are required. Its flexibility makes it ideal for applications involving dissimilar surfaces and where differing coefficients of thermal expansion are a consideration. Once fully cured the epoxy maintains an extremely strong bond under expansion, contraction and limited movement while also maintaining a good retention of strength over time and after environmental aging. With a 2:3 mix ratio it is a low viscosity epoxy. It flows smoothly for accurate dispensing.

Both the base and accelerator are coded in contrasting colors to ensure you know which half of the product you are using.

Recommended Applications

• Hard disk drive component assembly
• Potting where expansion and thermal changes may occur, such as solar panels and other construction applications
• Military bonding applications, for example bonding parts on movable transports
• Bonding ceramic, most plastics and glass to metal
• Attaching various substrates to masonry and stone
• Excellent for Cryogenic Bonding Applications

The 3M™ Scotch-Weld Epoxy Adhesive 2216NS is designed to perform under extremely frigid temperatures. Because it can withstand temperatures up to -423°F/-252°C it is ideal for cryogenic bonding applications. At room temperature it offers a 90 minute work life to allow for repositioning and adjustments. It will slowly cure over 7 days, but can be heat cured to reduce this to as little as 30 minutes (at 200°F/93°C.) It has a bonded shear strength that can withstand up to 3,200 psi at 72°F/24°C.

Understanding Epoxy Adhesives
Epoxy adhesives, including 5 minute epoxy are part of the class of adhesives called "structural adhesives," which include polyurethane, acrylic, cyanoacrylate and others. Epoxies are formulated as liquid rea¬ctive 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 adhesive (often referred to as epoxy glue) is 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. It is 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 epoxy for plastic flexible or epoxy for metal rigid, epoxy resin transparent or opaque, quick setting or slow setting. The versatility with which these adhesives can be formulated helps meet almost any requirement for bonding wood, metal, glass, stone and various plastics.
