Anti-pollution paint is aimed at improving resistance against stain, oxidation and polluters including carbon, the main culprit of air pollution,
by highlighting the resin's tight-knit structure on the weather-resistant coating's upper layer.
Dongbu Steel produces Sun-Clean prepainted steel sheet.
USAGE
-Sandwich panels
-Factory complex buildings
DESCRIPTION
Product Features
Compared old coated steel sheet, dust or other matters will not stick
With excellent acid resistance and alkaline properties, prepainted steel sheet is used for panel materials and exterior materials for factories
Compared to old steel sheet, it has excellent surface conditions against pollution matters such as sulfurous acid gas.
Treatments, such as building cleaning, are made simple because of excellent contamination resistance.5
Excellent atmospheric corrosion resistance
Fundamentals of Product
Uses a very fine resin, which has hydrophilic properties. It protects against pollution matters that stick when it. rains improved contamination resistance of by melamine on the surface, pollution matters cannot penetrate the surface although cuts are contaminated.
Property Comparison
Carbon black pollution assessment results
Sunclean has been proven to possess the greatest anti-pollution properties, showing the least amount of change in color in comparison with conventional steel sheet
Drop 0.5% carbon black solution on the Sunclean product and heat at 80˚C for 24~48 hours. Wash with water and examine the color difference.
