Bond, Laminate, Protect
3M™ Scotch-Weld™ Epoxy Adhesive 2290 is designed to coat and bond metal substrates, including steel and aluminum. This epoxy is a low (21% solids) formulation with very low viscosity. 3M™ Scotch-Weld™ Epoxy Adhesive 2290 adhesive can be applied in a variety of methods including: brushing, flow coating, dip coating, roll coating, knife coating and spraying. it is ideal for assembling metal laminations and various applications on metal cores, rotors and motors and wire windings. B-staging coated and dried parts are optional; allowing final cure up to 3 months later.
Assemble laminated steel cores for electrical motor stators and rotors
Adhere copper foil to B-staged epoxy in the manufacture of printed circuits
Coat, protect and utilize coils and electronic subassemblies
Thin metal stack laminations such as those used in magnetic tape heads
One-part heat cured epoxies are rigid adhesives that have outstanding strength when measured at elevated temperatures. These adhesives require a thermal cure, typically around 250-350°F (120-180°C) for 40-60 minutes, to achieve full strength. They generally have the highest strength and overall performance. They also provide the best resistance to high temperatures, solvents and outdoor weathering. Epoxy adhesives usually require clean, abraded surfaces to obtain maximum bond strength.
