1 Scope

This standard specifies the determination of PVDF content in coatings (dry film) after coating of hot melt fluororesin coatings by melting temperature drop method. Principles, test procedures, results calculations and representations. This standard applies to the test of PVDF content in hot melt fluororesin coating (dry film) with PVDF content of not less than 50%.

3 Terms and definitions

The following terms and definitions apply to this document. 3.1 Hot melt fluororesin coating (dry film) hot-meltfluorocarbonresincoating (dryfilm) Polyvinylidene fluoride (PVDF) resin and acrylate resin as the main film-forming materials, adding pigment filler (no varnish), solvent, auxiliary The coating prepared is coated on a metal surface and cured by high temperature baking. 3.2 Polyvinylidene fluoride (PVDF) content polyvinylidenefluoride (PVDF) content PVDF accounts for the mass fraction of the main film-forming resin in the hot-melt fluororesin coating.

4 Principle

According to the compatible polymer blend system, the melting temperature of the crystalline polymer increases with the content of the non-crystalline polymer compatible therewith. And the phenomenon of decline, using a differential scanning calorimeter (DSC) to measure pure PVDF resin, standard samples of different PVDF content and Measuring the melting temperature of the sample coating, melting the PVDF content of the standard sample to the standard sample of different PVDF content and the pure PVDF resin The temperature difference is plotted, and the melting temperature difference between the coating of the sample to be tested and the pure PVDF resin from which the coating is prepared can be obtained by looking up the curve. The content of PVDF in the resin coated.
