    INTRODUCTION

    PPGI & PPGL also known as pre-coated steel or color coated steel coil, It is a product made of hot-dip galvanized steel sheet, hot-dip galvalume steel sheet, electro galvanized steel sheet, etc. After surface pretreatment, one or several layers of organic coating are applied on the surface, and cured by baking.

    The total thickness of the pre-panted galvanized steel coil is composed of the base steel, coating,primer,top paint and protective layer thickness. The top paint thickness is 10-25μm, and the back paint thickness is 5-20μm.

    • ❀Finished coating:

      RPE, SMP, HDP,PVDF,Other paints.

      Function: prevent the damage of ultraviolet ray. When the top paint film reaches a certain thickness, a dense covering layer is formed to reduce the permeability of water and oxygen.

    • ❀Primer:

      Polyurethane, Epoxy, PE

      Function: enhance the adhesion between top paint film and base metal. Even in case of water penetration, the top paint film will not fall off.

    • ❀Chemical conversion coating:

      Function:Increase the adhesion between the metallic layer and coating film.

    • ❀Metallic coating:

      Function: metal coating provides basic protection for steel. Commonly used coating metals are galvanized, galvanized and other alloy metals.

    • ❀Cold rolled steel sheet:

      Cold rolled steel sheet is usually used as base material, which has certain wear resistance and hardness, and good fatigue strength and toughness.
