Handling precautions
- Clean the substrate surface using a sandblaster or grinding wheel to remove rust and oxidation.
- Use a residue-free solvent or cleaning agent to thoroughly clean the prepared surface.
- Apply the adhesive immediately after cleaning to prevent re-oxidation, rust, or contamination of the surface.
- Avoid touching the cleaned surface with bare hands; if touched, clean again with a suitable cleaning agent.
- Ensure no liquids come into contact with the bonding surfaces during application.
Adhesive Mixing
Use the appropriate adhesive dispensing gun to extrude and apply the adhesive directly to the bonding area for optimal performance.
