Nippon Paint Hydro Wood & Metal Primer  Anti-Corrosive Water-Based Primer for Wood, Steel, and Aluminium

Product Overview

Nippon Paint Hydro Wood & Metal Primer is an innovative water-based green primer formulated for both interior and exterior use. This multi-surface sealer is engineered with advanced anti-corrosive agents, providing robust protection for iron and steel against rust and oxidation.

Unlike conventional primers, its unique waterborne formula ensures Low VOC (Volatile Organic Compounds) and low odor, making it the ideal choice for eco-sensitive environments such as hospitals, schools, and residential bedrooms. It offers exceptional adhesion to a variety of substrates, including wood, galvanized steel, and aluminium railings. This primer creates a smooth, matt white base that enhances the finish of water-based topcoats, ensuring a professional and long-lasting result.
