  • 3. Mission Statement LCS Belgium provides consultancy services to all users of adhesives, encapsulants, coatings, sealants and fluids in order to cost-effectively improve clients’ development, implementation, manufacturing and quality control processes & procedures.LCS - Winter 2011 - V 1.5 Copyright LCS ® 3
  • 4. Oh, yes !LCS - Winter 2011 - V 1.5 Copyright LCS ® 4
  • 5. NASA – Spaceshuttle - Damage Ablative Tile Material: ceramicLCS - Winter 2011 - V 1.5 Copyright LCS ® 5
  • 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 componentsLCS - Winter 2011 - V 1.5 Copyright LCS ® 6

  • 8. What’s “Bonding” ? Definition Joining of two substrates by means of a third medium = the adhesive Adhesion vs CohesionLCS - Winter 2011 - V 1.5 Copyright LCS ® 8
  • 9. What’s “Bonding” ? Mechanisms • Vanderwaals – Glassplates experiment • Chemical – Si primer • Mechanical – Surface roughnessLCS - Winter 2011 - V 1.5 Copyright LCS ® 9
  • 10. But what’s really on the ‘Surface’ ?! Surface condition of substrates !!!LCS - Winter 2011 - V 1.5 Copyright LCS ® 10
  • 11. But what’s really on the ‘Surface’ ?!LCS - Winter 2011 - V 1.5 Copyright LCS ® 11
  • 12. Pretreatment of substrates • Degreasing: cloth, vapour, ultrasonic • Grinding: roughen = > surface • Blasting: grit-, ice- . NON-recirculating ! • Primers: silanes – thickness = µm • Chemical etch: bv Aluminium • Flame & Corona: foil & sheet • Plasma: vacuum & atmospheric – CA! • Laser: surface structure changeLCS - Winter 2011 - V 1.5 Copyright LCS ® 12
  • 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 K07M01R32C.movLCS - Winter 2011 - V 1.5 Copyright LCS ® 13
  • 14. Failure Types • Cohesion failure: lack of cure • Material failure: plasma treated + fully curedLCS - Winter 2011 - V 1.5 Copyright LCS ® 14

  • 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 !LCS - Winter 2011 - V 1.5 Copyright LCS ® 31
