How Long is the Shelf Life of Rust Paint?

[JoannaAnn]

The specific rust-proof duration depends on factors such as the type of paint, usage environment, and matching paint systems. Detailed explanations are as follows: 1. Ordinary anti-corrosion paints, such as red lead rust paint, iron red rust paint, and alkyd paint, generally last 3-5 years. 2. Heavy-duty anti-corrosion paints, like epoxy zinc-rich primer, epoxy mica iron intermediate paint, and fluorocarbon paint, can theoretically last up to 20 years. 3. If topcoats such as chlorinated rubber or acrylic polyurethane paint are used, the duration can reach about 10 years. Below is relevant information: The main components of rust paint are rust-proof pigments and film-forming substances. It is a coating that protects metal surfaces from corrosion caused by air, water, or electrochemical reactions. Rust paint is divided into two major categories: physical and chemical rust paints.
