Understanding Adhesion
Adhesives & Double Coated Bonding Tapes
•Adhesives...perhaps the first technology
•Adhesion/cohesion...working together for application success
•Application Success Factors
Forms of adhesive
Strength of Adhesive
Substrates – the materials to be bonded
Stresses on the substrate & bond
End Use Environment – exposure & resistance
Part Geometry – Pros & Cons for Bonding
Application methods – adhesive form guides choice of method
Brushing or rolling
Flow
Spraying
Taping
Variables affecting application success
Adhesive economics: True value = applied cost per unit
•Replacing mechanical fasteners with adhesives & tapes
Single Coated Tapes
Reclosable Fasteners
