After stabilization, the strand is dipped in a low-temp (15–35°C) phosphate bath, forming a thin crystalline film for rust protection and coating adhesion. Film thickness: 1–3μm.
We offer phosphorus-free and boron-free film agents to help steel strand enterprises meet environmental protection emission standards

Hold the three major international system certifications of ISO 9001, ISO 14001 and ISO 45001. We own over 20 patented technologies
Short-term rust protection between processes, preventing white rust on wire surfaces.
Phosphate film lowers inter-wire friction, reducing scratches and wire breakage during transport and storage.
Provides an excellent base for epoxy coating / grease — no delamination, no blistering.
Low-temperature process introduces no hydrogen; strand fatigue performance remains unaffected.
Room-temperature operation, no heating required — energy consumption reduced by 60%+ vs. medium-temp phosphating.
We provide comprehensive wire production chemical solutions to global customers—from high-performance phosphating solutions to advanced dry wire drawing lubricants.
