6. Advantages of Adhesives
• Easy & Fast: less rework
• Also for dissimilar materials
– e.g. metal-plastic & thick-thin
• Higher Strength: uninterrupted joint
– No or less weak points
• Improved Stress-distribution & -reduction
– Higher fatiguestrength
• Sealing: corrosion prevention
– Liquid- & gastight
• Damped Vibrations – less Noise S&R
• Light: weight reduction
• Esthetic: invisible
• Bonding also “Thin” & “Small” components
• Less components

8. What’s “Bonding” ? Definition
Joining of
two substrates
by means of a
third medium
= the adhesive

13. Failure Types
• Cohesive failure: in the adhesive
• Adhesive failure: on the surface of at least
one of the substrates
• Material Failure: one of both substrates
• Mixed Failure: a combination of the above

31. Conclusie
De enige weg om succesvol kleefprojecten
te realiseren is, dat het “Triumviraat” van
– de klant met zijn project
– de lijmfabrikant met zijn adhesief
– de machinefabrikanten met hun equipment
intensief en met kennis van zaken
samenwerkt, van in de designfase en rond
alle aspecten van de toepassing.
Succes verzekerd !
