The crystallization and formability of polyvinylidene fluoride resin (PVDF) coated steel sheet were examined by the thin film X-ray diffraction method. The integrated intensity of (020) diffraction peak increased and the integrated intensity of (110) decreased with increasing cooling water temperature after galzing of fluoride resin and acrylic polymer. At the temperature of cooling water from 20 to 45℃, the lattice spacing of (020) decreased continuously, and that of (110) increased continuously. Above 45℃, the lattice spacings of (020) and (110 did not change. At the temperature of cooling water from 20 to 40℃, the integral breadths and the full widths of half maximum of (110) and (020) did not change, while they decreasd continuously above 40℃. It was clarified that when the cracks in PVDF are generated, the integral breadth decreases, and therefore when the decrease of the integral breadth is suppressed, the formability of the PVDF-coated steel sheet becomes excellent.
