  • Polyolefin resin composition for metal coating, and resin film and resin-coated metal material using the same
    Patent number: 9074083
    Abstract: The present invention provides a polyolefin resin composition for metal coating, which is excellent in separation resistance, weather resistance and corrosion resistance, can be industrially produced without difficulty even by an existing apparatus, and is assured of excellent scratch resistance without using a surface coating agent; a resin film using the composition; and a resin-coated metal material. The polyolefin resin composition for metal coating comprises at least (A) a polyolefin resin, (B) a layered inorganic material, (C) an olefin containing oligomer containing a functional group having polarity and (D) a rubber-like elastic material.
    Type: Grant
