Anti-Flash Rust Agent R-729A

Product Overview:

Anti-Flash Rust Agent R-729A can be used either on its own or in combination with other water-soluble corrosion inhibitors. In water-based coatings, it exhibits particularly noticeable anti-flash rust protection, especially on submerged arc welds and cast iron, with virtually no flash rust when used at concentrations exceeding 1%. R-729A has excellent anti-flash rust properties and outstanding storage stability.

Physical Properties:

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