VCI-708 environmentally friendly rust remover is a high-tech product with excellent performance that replaces harmful strong acids such as hydrochloric acid, nitric acid, and sulfuric acid for pickling.
It is an aqueous solution derusting product composed of a variety of surfactant, penetrants, accelerators, organic complexing agents, etc.
VCI-708 can clean all metal materials without any adverse effects on subsequent processes (anti-rust, electrophoresis, plastic spraying, baking paint, etc.).No "hydrogen embrittlement", no need for high-temperature baking and special cleaning, and no "over-corrosion".Even if the product is immersed in the environmentally friendly rust remover for a long time, there is almost no "weight loss" phenomenon, which protects the original mechanical properties and processing properties of the steel.
