Phosphorous Acid (70%)
Product Overview:
Phosphorous acid at 70% concentration is a versatile reducing acid used across fire protection, water treatment, and chemical manufacturing applications. It is commonly employed as a chemical intermediate for manufacturing flame retardants and fire protection additives used in coatings, plastics, and textiles. Additionally, it serves as a raw material for phosphonate-based scale and corrosion inhibitors used throughout industrial water treatment systems. Phosphorous acid is also utilized in agrochemical manufacturing as a precursor for fungicidal compounds. Furthermore, it finds applications in general chemical manufacturing processes requiring a strong reducing acid.
