Key Features and Benefits
- Versatile Application: Low viscosity formula allows for brushing, flow coating, dip coating, roll coating, knife coating, and spraying.
- Superior Strength: Provides exceptionally high shear and peel strength for durable, long-lasting bonds.
- B-Staging Capability: Dries to a tack-free film, allowing bonds to be made up to 3 months later, perfect for multi-stage processes.
- Excellent Wetting: Requires coating on only one surface, improving efficiency and reducing material usage.
- Heat-Curable: Achieves optimal strength through heat curing, ideal for high-performance industrial applications.
Product Details
3M Scotch-Weld Epoxy Adhesive 2290 is a 21% solids formulation with very low viscosity. It requires heat curing, typically around 250°-350°F (120°-180°C) for 40-60 minutes, to achieve full strength. This epoxy is available in a convenient 5-gallon pail, suitable for large-scale industrial use.
Applications
This versatile epoxy is perfect for:
- Assembling laminated steel cores for electrical motor stators and rotors
- Adhering copper foil to B-staged epoxy in printed circuit manufacturing
- Coating and protecting coils and electronic subassemblies
- Bonding thin metal stack laminations, such as those used in magnetic tape heads
Usage Tips
For optimal results, ensure surfaces are clean and dry before application. When using for lamination, a heat press during the curing process is recommended. Always refer to the manufacturer's guidelines for specific curing times and temperatures based on your application.
