Bonding of silicone rubbers on metal (2) physical chemistry ofadhesion tIn the previous paper of this series, three primer formulations were tested for the adhesion of two differentgrades of silicone elastomer on aluminum studs. The simple approach consisting at analyzing primers’chemical composition was not suitable to generate a formulation allowing “universal” adhesion of siliconeelastomer on metal. In the second part of this series, we studied more specifically the properties of theprimer films (topology, thickness and roughness, surface energy) and of the primer/silicone elastomerinterphases after peeling test (hardness, profilometry of the fracture profile). A final discussion stresseson the parameters which govern the selectivity of a silane-based primer...
