•    Keyue® Polyurethane Rust-Resistant Anticorrosive Paint is a low-surface-treatment coating engineered for refurbishment and protection of steel structures (bridges, machinery, tanks, pipelines). Based on polyurethane resin with rust-inhibiting pigments and passivating agents, it exhibits excellent corrosion resistance, strong substrate adhesion (even to firm residual rust), outstanding flexibility, and UV aging resistance. Complete removal to bare metal is not required—sound residual rust can remain to be passivated by the coating.

  
  

  
  

  
  

     ●  Strong adhesion to rusted substrates

     ●  Anticorrosion & de-rusting synergy: reacts with residual rust to form a passivating barrier

     ●  Simple construction by spray/roller/brush
