Anti-Flash Rust Agent R-729A

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

pH Value (25°C): 9-11

Density (g/cm³): Approximately 1.10

Solubility in water: Forms a transparent solution when dissolved in water

 

Application Fields:

 

R-729A is suitable for use in water-based acrylic latex systems, water-based two-component epoxy, epoxy rich in zinc, and other water-based coating systems.

 

Main Characteristics:

 

Exhibits excellent anti-flash rust protection, especially on rust-prone substrates such as cast iron, welds, and submerged arc welds.

Also applicable to substrates such as hot-rolled carbon steel, cold-rolled steel, galvanized iron, silicon steel, and more.

 

Usage and Dosage:

 

For general carbon steel substrates, add 0.2-1% of the total coating.

For welds and cast iron substrates, add 0.5-1.5% of the total coating.

Add during the paint formulation stage.
