  • Lubricating resin coated steel strips having improved formability and corrosion resistance
    Patent number: 5061575
    Abstract: A zinc, zinc alloy or aluminum alloy plated steel strip having chromate coatings on both surfaces is coated with a lubricating resin composition for improving formability and corrosion resistance. In one form, a resin composition including a base resin, silica, a high-melting polyolefin wax and optionally, a low-melting polyolefin wax is applied on both surfaces for improving formability. In a second form, a resin composition including a base resin, silica, and a powder fluoro resin is applied on both surfaces for improving corrosion resistance. In a third form, the chromated steel is coated with a resin composition including a base resin, silica and a solid lubricant on one side and with a resin composition including a base resin and silica on the other side for improving both formability and corrosion resistance.
