The Ultimate Solution to Flash Rust Troubles in Fire-Retardant Coatings! A Must-Read!

Fire-retardant coatings are widely used in fields such as construction and shipbuilding. Their surface layers are relatively thin, making them prone to oxidation, rust, and other issues that lead to flash rust. The main causes of flash rust in fire-retardant coatings are as follows:

Poor coating surface quality: Defects on the coating surface, such as incomplete cleaning or oxidation, can trigger rust formation.
Weak coating adhesion: Insufficient adhesion between coating layers or between the coating and the substrate not only causes peeling but also makes the coating vulnerable to corrosion, resulting in flash rust.
Excessive humidity: High environmental humidity or overly thick paint films slow down moisture evaporation, leading to delayed drying and eventual flash rust.
Cracking: Differences in elasticity between the coating and the base material, or significant temperature changes beneath the coating, can cause the coating to expand, contract, and crack. This exposes the base material to air, leading to rust and flash rust.

Anti-flash rust agents effectively prevent flash rust and protect the coating surface by forming a protective film. This film isolates oxygen and other corrosive substances from the substrate, enhancing the coating’s durability and service life. Additionally, they improve the fire-retardant coating’s application performance and chemical resistance, boosting adhesion during construction—critical for withstanding harsh industrial environments prone to acid, alkali, and corrosion.
