Overview

Part of a B/A system, 3M™ Scotch-Weld™ Epoxy Adhesive 405 provides good shear and peel strength along with good impact resistance for reliability and durability. It bonds extremely well to many surfaces including metal, glass and ceramic. Workers and customers will appreciate its lower odor compared to traditional mercaptan based fast cure epoxies and acrylic adhesives. Our two-part, 2:1 mix ratio, toughened epoxy structural adhesive helps your productivity with its 5 minute work life and accelerated cure. When cured, it provides excellent shear and peel strengths along with good impact resistance and durability. It bonds extremely well on many metal and composite surfaces.

What Are 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. 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.
