RESUMO:

This work aims to study fluoropolymer nonstick coatings in deep drawing shaped pans, analyzing the effect of paint formulation in case of nonstick peeling defects after the deep stamping process. For this, different inks were formulated and applied to aluminum disks, which later went through the stamping process. The different coatings studied presented distinct levels of peeling, indicating that the defects incidence is directly correlated with the coating formulations. It has been observed that peeling may arise from adhesive failure between the paint layers close to the coating with the substrate by scanning electron microscopy (SEM) and X-ray photoelectric (XPS) technique. The defect may be related to the lack of stretching resistance of the coating during the stamping process, a property that was evaluated through tensile tests.
