Loctite EA 3450 - 25 ml (epoxy resin, universal, two-compound)

Product description:
LOCTITE EA 3450 is a two component epoxy adhesive which cures rapidly at room temperature after mixing. It is a metal bonding adhesive which develops high strength. The gap filling properties make this adhesive system suitable for rough and poorly fitting surfaces made from metal, ceramic, rigid plastics or wood. Applications include bonding aluminum window frames and GRP panels. Further information on the product can be obtained from your local technical department:

Steps to achieve the best adhesive results:
1. For best performance part surfaces should be clean and free of grease. Use LOCTITE SF 7063.
2. For high strength structural bonds, remove surface contaminants such as paint, oxide films, oils, dust, mold release agents and all other surface contaminants.
3. Dual Cartridges: To use simply insert the cartridge into the application gun and start the plunger into the cylinders using light pressure on the trigger. Next, remove the cartridge cap and expel a small amount of adhesive to be sure both sides are flowing evenly and freely. If automatic mixing of resin and hardener is desired, attach the mixing nozzle to the end of the cartridge and begin dispensing the adhesive. For hand mixing, expel the desired amount of the adhesive and mix thoroughly. Mix for approximately 15 seconds after uniform color is obtained. Bulk Containers: Mix thoroughly by weight or volume in the proportions specified in Product Description section. Mix vigorously, approximately 15 seconds after uniform color is obtained.
4. For maximum bond strength apply adhesive evenly to both surfaces to be joined.
5. Application to the substrates should be made within 20 minutes. Larger quantities and/or higher temperatures will reduce this working time.
6. Join the adhesive coated surfaces and allow to cure at 25 °C for 24 hours for high strength. Heat up to 93 °C, will speed curing.
7. Keep parts from moving during cure. Contact pressure is neccesary. Maximum shear strength is obtained with a 0,1 to 0,2 mm bond line.
8. Excess uncured adhesive can be wiped away with organic solvent (e.g. Acetone).
9. After use and before adhesive hardens mixing and dispensing equipment should be cleaned with hot soapy water.
