High definition Ppgi Corrugated Steel Sheet - Stone pattern prepainted coils/color coated design pattern steel coils – Yifu

Product Description

What is design PATTERN PPGI

STONE pattern coated steel coil is based on galvanized, aluminized zinc substrate, coated with special colors and modulated graphics. Because the pattern is similar to brick, it is called brick color coated steel coil. It is mainly used in architecture, decoration and so on.

Because there are many types of STONE/MARABLE patterns, the paint can be customized.

Chemical Composition of The Product

❀Top paint film:
RPE, SMP, HDP,PVDF,Other paints.
Function: It functions as a sunlight proof cover, especially prevent the destroy by the ultraviolet rays. When the top paint film reaches a certain thickness, it forms a compact cover, and reduce the water and oxygen permeability.

❀Primer paint film:
Polyurethane, Epoxy, PE

Function:Strengthen the adhesiveness between the top paint film and the basemetal. Even permeable water happens, the top paint film will not peel off. There is corrosion inhibitor which is corrosion resistance. Polyurethane is necessary for higher processing flexibility and weather resistance requirements.

❀Passivation layer
Function:Increase the adhesion between the metallic layer and coating film. Extend life span also.

❀Metallic coating
Function:The metallic coating provides the fundamental protection for the steel.

The popular coating metal are galvanize, galvalume and other alloyed metals.

❀Substrate steel
Cold rolled steel is usually used as substrate, it decides the mechanical properties and the steel shape and flatness.

❀Back paint film
Epoxy, Modified PE.

Back paint can sustain color in good condition and has good binding.
