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
Structural adhesives bond by chemical reaction
Non–structural adhesives bond by physical change
Pressure sensitive adhesives bond on contact
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
Adhesive economics: True value = applied cost per unit
•Replacing mechanical fasteners with adhesives & tapes
Single Coated Tapes
Reclosable Fasteners
