3M™ Scotch-Weld™ Epoxy Adhesive 1469 is a one-part, thermosetting liquid adhesive that provides exceptionally high strength at temperatures from -70°F to 300°F (-57°C to 149°C). This white to cream colored adhesive can be applied by knife coating, trowel, roller coating, pump and high pressure injection methods. Standard equipment is available which allows pumping directly from five-gallon pails.
Excellent retention of strength after aging in typical environments
Exceptionally high strength properties at service temperatures from -70°F to 300°F (-57°C to 149°C)
Only pressure sufficient to ensure contact between mating surfaces is required
Little volatile by-products given off during cure
Easy application by knife coating, trowel, roller coating, pump and high pressure injection methods
Excellent High Temperature Strength Retention
3M™ Scotch-Weld™ Epoxy Adhesive 1469 eliminates the need for metering or mixing and weighing two part systems. This product offers exceptionally high performance at service temperatures ranging from -70°F to 300°F (-57°C to 149°C). Another beneficial feature is that it releases little volatile by-products during its cure process. Epoxy Adhesive 1469 provides excellent retention of strength after aging in typical environments. Cure profile: 2 hours at 350°F (177°C).
Metal to metal bonding
The strong, reliable formula enables curing with only pressures sufficient to insure contact between mating surfaces required. This flow-able, syrup-like adhesive is a versatile product that can be applied knife coating, trowel, roller coating, pump and high pressure injection to meet a variety of dispensing requirements and situations. A lower viscosity for ease of application can be obtained by warming 3M™ Scotch-Weld™ Epoxy Adhesive 1469 to 100-120°F (38-49°C). NOTE: This epoxy may start to thicken if held at 120°F (49°C) for more than 3 hours.
General Characteristics of Epoxy Adhesives
Epoxies are polymer 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. One-part epoxies have a limited shelf life at room temperature, and may require cold storage and shipment. However, they offer long work lives after application and do not require mixing at application time.
Epoxy 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.
