Two Basic Types of Rust Inhibitors

Rust is a major problem in North America. It erodes the integrity of metal components. From car parts to industrial machinery, metal can be damaged by rust. Fortunately, by being proactive, this problem can be impeded. One common method is the application of rust inhibitors.

What Are Rust Inhibitors?

As the name indicates, a rust inhibitor protects metal components from rust and rusting. They are applied to the surface of a metal object. In doing so, a rust inhibitor creates a fine barrier between the metal and the negative impact of external contaminants.

Two Types

Two types of rust inhibitors are currently available for application. These are solvent-based inhibitors and water-based inhibitors. Both provide protection to a machine or mechanical system’s metal parts.

  1. Solvent-Based Inhibitors: This type of rust inhibitor is applied directly to the metal. It forms a coating on the metal’s surface. This has been the standard means of providing protection from water/moisture that contributes to rusting
  2. Water-Based Inhibitors: These are applied to the metal surface using a spray or immersion method. A water-based rust inhibitor reduces the susceptibility of the metal to oxidation, therefore decreasing the instance of rusting. It is more economical than solvent-based rust inhibitors.

Choosing a Rust Inhibitor

Water-based and solvent-based inhibitors are used to prevent rust and corrosion on metal surfaces. They are applied to automotive parts, tooling and cold rolled sheets and coils. Industries use them to ensure metals and cast or machined components are protected in use, in storage or during shipment.
