Abstract
A resin coated metal sheet includes: a metal sheet; and a resin layer configured to coat at least one face of the metal sheet. A pushing depth of the resin layer on a side adhered to the one face of the metal sheet is 100 nm to 250 nm, the pushing depth being determined by a nano indentation test, and a melting point of the resin layer is 210° C. to 270° C.
Claims7
A resin coated metal sheet comprising:
- a metal sheet;
- and
- a resin layer configured to coat at least one face of the metal sheet, wherein
- a pushing depth of the resin layer on a side adhered to the one face of the metal sheet is 100 nm to 250 nm, the pushing depth being determined by a nano indentation test performed at a load of 50 μN under conditions with a stage temperature of 30° C., a pushing depth of 1,000 nm, and a maximum load holding time of 5,000 msec, and
- a melting point of the resin layer is 210° C. to 270° C.
