Adhesion of thermoplastic polyurethane elastomer to galvanized steel

Véronique Michaud, Basile Golaz

When a thermoplastic polyurethane elastomer (TPU) is co-molded with galvanized steel, the subsequent adhesion and its durability are very sensitive to the chemical bonds created at the interface. Silane coupling primers are known for enhancing adhesion bet ...

Texture Formation in Hot-Dip Galvanized Coatings : Nucleation and Growth of Anisotropic Grains in a Confined Geometry

Aurèle Mariaux

Continuous hot-dip galvanization is a process during which steel sheets are coated with a layer of Zn-Al alloy to protect them against corrosion. As the name indicates, this is achieved by dipping the preheated sheet into a bath of molten alloy. The sheet ...
