Epoxy anti-corrosion primer (red lead) is a two-component red heavy-duty anti-corrosion primer. It is based on epoxy resin and is made with red lead anti-rust pigments, fillers and special additives. It relies on the physical shielding and chemical corrosion inhibition of red lead pigment to achieve rust prevention. It is a classic anti-corrosion primer for traditional steel structures and mechanical equipment. Core features Red lead corrosion inhibitor and anti-rust When the red lead pigment (main component is lead tetroxide) comes into contact with the metal substrate, it will form a dense passivation film, which can not only shield the penetration of water vapor and oxygen, but also inhibit the corrosion of steel through chemical corrosion inhibition. It has stable anti-rust performance and is suitable for moderately corrosive environments indoors or dry outdoors. Strong substrate adhesion Epoxy resin has strong binding force with ferrous metal substrates such as steel and cast iron. It has good surface compatibility with rust-removed substrates and the paint film is not easy to peel or fall off. It can be used with various coatings such as epoxy cloud iron medium paint, alkyd topcoat, polyurethane topcoat, etc., and has excellent inter-layer compatibility. Convenient construction and moderate cost It can be applied in a variety of construction methods such as brushing, roller coating, and spraying. It can be cured into a film at room temperature and has lower requirements on the construction environment. Compared with epoxy zinc-rich primers, it is more cost-effective and is a cost-effective choice for anti-corrosion of small and medium-sized steel structures. Scope of application Steel structure engineering: steel columns and beams of factory buildings, municipal steel frames, and bottom layer anti-corrosion of storage shelves. Mechanical equipment: anti-rust primer for general machine tools, agricultural machinery and mining equipment accessories. Infrastructure field: protective coating of water pipelines, small bridge components, and tower bases.
