| What is Prepainted Steel? |
Color Prepainted Galvanized PPGI Steel Coils is a product made of
cold rolled steel plate and galvanized steel plate by surface
pretreatment (degreasing, cleaning, chemical conversion),
continuous coating (roll coating), baking and cooling. Coated steel
sheet has light weight, beautiful appearance, good corrosion
resistance and can be processed directly. It provides a new raw
material for construction, shipbuilding, vehicle manufacturing,
household electrical appliances, electrical industry, etc. It has
played a good role in replacing wood with steel, efficient
construction, energy saving, pollution prevention and other good
results

Prepainted Galvanized Steel Coil/PPGI coating film introduction
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.
