LOCTITE® EA 9497

LOCTITE® EA 9497™ is a medium viscosity, two component,room temperature curing epoxy adhisive that bonds a wide variety of materials making it suitable as a general purpose adhesive. LOCTITE® EA 9497™ is ideal for heat dissipation applications such as bonding metal sheets for high heat transfer and potting electrical components. It is good for high compression strength applications, as well as high Tg applications with demanding hot strength requirements.

Directions for Use

For Assembly
1. For best performance surfaces for bonding should be clean, dry and free of grease. For high strength structural bonds, special surface treatments can increase the bond strength and durability.
2. To use, resin and hardener must be blended. Using bulk containers, mix thoroughly by weight or volume in the proportions specified in the Product Description Matrix. For hand mixing, weigh or measure out the desired amount of resin and hardener and mix thoroughly. Mix approximately 15 seconds after uniform color is obtained.
3. Do not mix quantities greater than 4 kg in mass as excessive heat build-up can occur. Mixing smaller quantities will minimize the heat build-up.
4. Apply the adhesive as quickly as possible after mixing to one surface to be joined. For maximum bond strength apply adhesive evenly to both surfaces. Parts should be
assembled immediately after mixed adhesive has been applied
5. Working life of the mixed adhesive is 3 to 4 hours @ 22 °C. Higher temperature and larger quantities will shorten this working time.
6. Keep the assembled parts from moving during cure. The joint should be allowed to develop full strength before subjecting to any service loads.
7. Excess uncured adhesive can be wiped away with organic solvent (e.g. Acetone).
8. After use and before adhesive hardens, mixing and application equipment should be cleaned with hot soapy water.
