3. Surface preparation
The surfaces to be bonded are often contaminated, which first requires cleaning, often called degreasing. However, the physical and chemical properties of metal, polymer and ceramic surfaces are very different. It is therefore necessary to create reactive surfaces by modifying their surface composition, increasing their roughness or applying an adhesion promoter (primer)
3.1 Metal and polymer surfaces
The aim of pre-treatment is to remove poorly adhering surface layers. They generally involve degreasing and mechanical abrasion, identical for metals...
