In some cases, very high throughput speeds are reached in coil coating. In the very short time between application and drying zone the solvent composition must bring about good flow. Coil coatings must have good adhesion to the substrate and a high elasticity to prevent problems and spalling during the forming processes (punching, shaping and thermoforming). The paint should have sufficient hardness to ensure good mechanical strength during the forming process and during use. Depending on the application, the coating compounds must have good resistance to weather, corrosion and chemicals. The actual coil coating ...
