Easy-cleaning PPGI Coils
|Definitions for Easy-cleaning PPGI Coils|
|The easy-cleaning prepainted steel sheet is a new prepainted
steel sheet for outdoors construction. Its organic coating not
only has excellent properties of decoration and weatherproof
that common prepainted steel sheets might possess but also
has the special self-cleaning function. The factory buildings
built by the prepainted steel sheets of this kind needn’t any
manually-operated cleaning or maintenance, which can retain
the cleanness and glossiness of the prepainted steel sheets
applied to the walls and roofs only by rainwater, even those in
the industries and cities with poorer air quality, and can maintain
the high decorative property of the prepainted steel sheets.
|Different coating system might have different
contamination and cleaning property
|**Fluorocarbon coating: at the medium and low contamination
level, and easy to clean.
**common polyester system: at high contamination level, and
hard to clean.
**Easy-cleaning sheet: at medium and high contamination level,
easy to clean.
|Has excellent resistance to staining, which can prevent the
pollutants from being penetrated into the coating membrane.
Its good water solubility ensures that the rainwater can fully
cover the surface of the coating and cleanse the surface well.
