Anti-Flash Rust Agent R-703

Anti-Flash Rust Agent R-703

 

Product Overview:

 

Anti-Flash Rust Agent R-703 can be used either on its own or in combination with other water-soluble corrosion inhibitors. In water-based coatings, it provides excellent anti-flash rust protection, particularly on welds and cast iron, with almost no flash rust when used at concentrations exceeding 1%. R-703 does not contain nitrite and offers good anti-flash rust properties, extremely low foaming, and excellent hard water stability.

 

Physical Properties:

 

Appearance (20°C): Colorless to light yellow to reddish-brown transparent viscous liquid
