Adhesives Science 101Adhesive: Definition EN 923

Non-metallic substance capable of joining materials by surface bonding (adhesion) and the bond possessing adequate internal strength (cohesion)

March 24, 2016

non-metallic substance

joining materials by

adhesion & cohesion

Adhesives Science 101Adhesion and cohesion

March 24, 2016

Adhesion

Cohesion

Adhesion


33

Adhesives Science 101Adhesion

Ability to bond to the surface

Depends on

Surface energy

Surface roughness

Surface contamination

Surface wettability

March 24, 2016

Reliable adhesion needs reliable surface conditions and a liquid adhesive.


34

Adhesives Science 101Importance of cleaning

March 24, 2016

Adhesives bond to the surface

Contaminant

Substrate 2

Substrate 1

Adhesion CohesionAdhesive molecule

Any contaminants reduce bonding strength


35

Limited contact Liquid stays off the surface

Adhesives Science 101Surface wetting necessary for good adhesion

March 24, 2016

The liquid adhesive has to be in optimum contact to the surface

through surface preparation, e.g. cleaning, pretreatment

Optimum contact Liquid smooths onto the surface


36

Adhesives Science 101 Cohesion achieved by polymer-building

SolidLiquid

Cohesion needs proper cure of the adhesive

Wider is Better!


46

BondingPerfectly designed for material fit

Liquid adhesive

Adapts to gap and gap tolerances Adapts to surface roughness and voids Fills gap by 100% Bonds the joined parts, after change from liquid to solid Uses 100% of surfaces for adhesion


47

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
