Common Additives for Water-Based Anti-Rust Paint for Steel Structures

As industrialization and urbanization continue to advance, environmental quality exerts an increasingly significant impact on people's physical and mental health, thereby attracting growing attention. Environmental pollution, stemming from non-compliant materials and other factors, continues to threaten human health. Today's energy landscape grows increasingly severe and complex, with shifts in energy quantity, quality, and pricing. Consequently, water-based coatings—offering relatively reasonable costs alongside energy efficiency and pollution-free properties—are gaining widespread acclaim and experiencing rapid development. Below, we recommend several environmentally friendly additives commonly used in water-based steel structures.

High-Efficiency Universal Anti-Flash Rust Additive CK34: Composed of organic complexes and multiple polymer compounds, it synergizes with anti-corrosion pigments. It demonstrates outstanding anti-flash rust performance on metal surfaces like welds and cast iron, with excellent resistance in low-temperature, high-humidity environments. CK34 does not affect coating adhesion to substrates or salt spray resistance.

Polyacrylamide Salt Dispersant 2513 delivers exceptional wetting and dispersion effects for solid particles in various water-based systems. It enhances coating storage stability while improving gloss and leveling properties.

Dispersant 5040 is a polyacrylate dispersant designed for solid particles in various water-based systems, delivering outstanding wetting and dispersion effects. It effectively reduces viscosity and provides excellent system stability.

Wetting Agent SK1 is an alkyl polyoxyethylene ether. Low VOC, low odor, and APEO-free, it enhances freeze-thaw stability in coatings. Used for pigment dispersion, it significantly improves the flow properties of red and yellow pigment pastes. Serves as a post-stabilizing emulsifier for emulsion, boosting mechanical, freeze-thaw, and chemical stability. Easily soluble in water with low foaming.
