Description
Additin® RC-4803 Corrosion Inhibitor
Additin® RC-4803 is a high-performance, ashless corrosion inhibitor designed to deliver reliable rust protection in a wide range of lubricant and industrial fluid formulations. Based on a low-acid succinic acid derivative in a synthetic ester carrier, RC-4803 provides strong metal surface protection without compromising fluid stability or cleanliness.
This additive forms a durable, protective film on ferrous metal surfaces, effectively preventing rust and corrosion even in the presence of water or humid conditions. Its low treat rate efficiency makes it an ideal choice for modern lubricant systems where performance, compatibility, and cleanliness are critical.
