Color Steel

Anti-Pollution
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
The Anti-Pollution steel sheet used products
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.
