Adhesives Science 101 Adhesion
Ability to bond to the surface
• Depends on:
• Surface energy
• Surface roughness
• Surface contamination
• Surface wetability
Reliable adhesion needs reliable surface conditions and a liquid adhesive.

Adhesives Science 101 Surface wetting necessary for good adhesion
• Optimum contact • Liquid smoothes onto the surface
• Limited contact • Liquid stays off the surface
The liquid adhesive has to be in optimum contact to the surface through surface preparation, e.g. cleaning, pre-treatment

Joint Design Guidelines
• Maximize these forces
• Shear, tension, & compression
• Minimize these forces
• Peel, cleavage forces
• Minimize gap thickness
• Increase bond area
• Wider is better than overlap
• Use the appropriate test to qualify your adhesive
