01 / Product brief

6–12 Month Storage Protection After Phosphating

Water-displacing rust preventive oil designed for application as a final dip or spray after phosphating or passivation. Thin, self-levelling petroleum film seals the phosphate crystal structure and displaces residual moisture, providing 6–12 months inter-process corrosion protection during storage and transit.

Water-displacing formula penetrates surface moisture immediately after hot rinse — no flash rusting during air-drying phase. Thin film is compatible with most downstream painting and assembly operations without degreasing when applied at the correct concentration.
