Stannate specialty chemicals are known for their effectiveness as alkaline electroplating additives, metal complexing agents, battery additives, and corrosion inhibitors.

Stannates as Complexing Agents in Chemical Reactions

Reaxis’s stannate chemicals serve as effective complexing agents in various applications, forming stable complexes with metal ions, thereby regulating their reactivity and availability. Their complexing properties are particularly valuable in applications such as hydrogen peroxide stabilization, additives for battery electrodes and/or electrolytes,  metal extraction, wastewater treatment, and electroplating.

Stannates as Corrosion Inhibitors and Anti-fouling Agents

Reaxis stannate specialty chemicals can function as corrosion inhibitors and anti-fouling agents in various industrial settings. They form a protective barrier on metal surfaces, preventing the interaction between the metal and corrosive agents, such as water and oxygen. This ensures the longevity and reliability of essential equipment and infrastructure in industries like oil and gas, water treatment, and maritime. Furthermore, their anti-fouling properties help prevent the accumulation of biofouling on surfaces, improving efficiency and reducing maintenance costs of machines involved in the manufacturing process.

Stannates as Battery Additives

Stannates are emerging as promising battery additives in industrial manufacturing, owing to their unique electrochemical properties and ability to enhance the performance of batteries. Notably, REAXIS®E140, potassium stannate, and REAXIS®E144, sodium stannate can be used as additives in metal-air batteries to minimize and control corrosion/passivation/fouling at the electrode (anode)/electrolyte interface that leads to a decrease in charging capacity and charge retention over time. When integrated into the manufacturing process, these stannates form a protective layer on the electrode surface, mitigating issues like dendrite formation and electrolyte decomposition, which are common challenges in battery technology. Consequently, the incorporation of stannates like potassium and sodium stannate in battery manufacturing not only ensures enhanced energy storage capabilities but also promotes the longevity and safety of the final products, making them increasingly relevant in today’s rapidly evolving energy landscape.

Stannates as Electroplating and Metal Finishing Additives

In the electroplating and metal finishing sector, Reaxis stannate chemicals are employed as plating solutions and additives, acting as a source of tin deposits. Stannates are employed in the alkaline tin process. Both sodium and potassium stannates are used in this application with the potassium grade being preferred in high-speed plating applications given its high solubility. Their use in electroplating processes results in improved adhesion, corrosion resistance, and wear resistance for metal components, ensuring durability and performance in various applications, such as electronics, automotive, and aerospace. Reaxis offers a range of products including REAXIS®E140, potassium stannate, and REAXIS®E144, sodium stannate.
