In the field of advanced manufacturing, every smooth and precise metal component represents a promise of quality.
Rust prevention is not merely surface protection — it safeguards both efficiency and reliability throughout the production and logistics chain.
In the rust-prevention domain, Kerun’s flagship products — KR-AOD330PLUS and KR-AOD350 thin-film rust preventive oils — have become the preferred choice for an increasing number of customers, combining outstanding protection performance with a commitment to environmental responsibility.
PART 01 A Single Oil Film – Safeguarding Millions in Value
In harsh conditions such as humid air, salt spray, and long-distance transport, metal corrosion often occurs silently.
Kerun rust preventive oils form a dense and uniform protective film through a dual mechanism of efficient oil-film isolation and directional adsorption corrosion inhibition.
This film effectively blocks air, moisture, and salt, ensuring that metal components maintain their original gloss during storage and transportation (including ocean shipping).
KR-AOD350 – Fast Dehydration, Strong Separation, Long Service Life
Designed for water-containing conditions and continuous production lines, KR-AOD350 is known for its strong stability, rapid oil–water separation, low viscosity, and easy cleaning.
This product has been widely used in the steel pipe and gear industries, remaining stable and reliable after years of application, particularly suitable for processes involving residual moisture.
