Loctite EA 3479 - 500 g (epoxy resin with Al filler, up to 190 °C)

Product description:
LOCTITE EA 3479 is an aluminum filled, two component epoxy adhesive that is ideal for the repair and recovery of worn and damaged machinery. Typical applications include repairing worn parts such as shafts, housings, keyways and flanges as well as broken or damaged parts such as castings, pipes or fabrications. This product can be used for jobs as varied as filling cavities, levelling machinery, repairing cast-steel plates, making core moulds, applying a sacrificial coating or sealing leaking pipes. This product is typically used in applications with an operating range of -20 °C to +190 °C. Further information on the product can be obtained from the local technical department:

Steps to achieve the best adhesive results:
1. For best performance surfaces for bonding should be clean, dry and free of grease. You can use LOCTITE SF 7063. For high strength structural bonds, special surface treatments can increase the bond strength and durability.
2. Stir each component of resin and hardener separately, then measure out equal amounts of each.
3. Stir thoroughly together for up to two minutes until an even mix is achieved.
4. Apply the product to the working area with the spatula provided.
5. For larger breaks or fractures, the product can be applied to glass fiber matting or a similar support and used as a patch or bandage.
6. If used as a molding compound, use a wax, grease or silicone release agent to prevent adhesion to any surface. Functional strength is normally achieved after 10 to 12 hours, with full cure within 72 hours. These times are reduced with high ambient temperatures.

NOTE: Due to heat generation during the curing process, larger quantities tend to cure more rapidly.
7. Excess uncured adhesive can be wiped away with organic solvent (e.g. Acetone).
8. Keep the assembled parts from moving during cure. The joint should be allowed to develop full strength before subjecting to any service loads.
9. After use and before adhesive hardens, mixing and application equipment should be cleaned with hot soapy water.
