Description

Zinc Pyrophosphate is an inorganic salt with the chemical formula Zn₂P₂O₇, widely recognized for its role as a high-performance corrosion inhibitor and flame retardant. Its value lies in providing durable, non-toxic protection for metal substrates and enhancing the fire safety profile of various polymeric materials. This compound is essential for manufacturers in the coatings, plastics, and ceramics industries seeking effective and environmentally considered additive solutions.

Application

• Corrosion Inhibitive Pigments: A key component in primer formulations for automotive, marine, and industrial coatings to protect steel and other metals.
• Flame Retardant Synergist: Used in plastics, textiles, and wire & cable compounds to improve fire resistance and reduce smoke emission.
• Ceramic Glazes and Frits: Acts as a opacifier and fluxing agent to enhance the durability and finish of ceramic products.
• Dental Cements: Employed in certain dental material formulations for its biocompatibility and setting properties.
• Lubricant Additive: Serves as a solid lubricant or anti-wear agent in high-temperature greases and composites.
• Catalyst and Catalyst Support: Utilized in specific organic synthesis and dehydrogenation processes.
