    Diammonium Citrate solution in Surface Treatment

    Lohtragon® B98 based on Diammonium Citrate solution is a multifunctional additive that enhances surface treatment processes. Acting as a conductivity enhancer, buffering agent, and complexing agent, it prevents precipitation and ensures a uniform distribution of metal ions in the solution. This results in even coating thickness, more efficient deposition processes, and extended bath life -  making it a valuable component for achieving high-quality surface finishes.

    Key benefits of Diammonium Citrate solution in Surface Treatment:

    • Improves metal ion distribution in plating baths
      • Enables uniform coating thickness and consistent surface finishes across complex geometries.
    • Enhances bath stability and prevents precipitation
      • Extends bath life by reducing unwanted side reactions and sediment formation.
    • Supports faster and more efficient deposition
      • Boosts process reliability and throughput in electroplating and surface treatment applications.


    Lohtragon® B98 in Chemical Synthesis 

    Diammonium Citrate solution serves as a versatile auxiliary material in chemical synthesis. Its role as a buffering agent and catalyst stabilizer ensures controlled pH levels, leading to precise and efficient reactions. By enhancing stability throughout chemical processes, it supports consistent results and improved overall performance in industrial applications.

    Key benefits of Lohtragon® B98 in Chemical Synthesis:

    • Maintains stable pH for precise reaction control
      • Functions as a buffering agent to stabilize reaction environments, critical for sensitive syntheses.
    • Stabilizes catalysts in complex formulations
      • Enhances catalyst lifetime and effectiveness in various industrial chemical processes.

    Lohtragon® B98: the benefits of aqueous solutions

    Aqueous solutions provide clear operational advantages compared to solid products. Many industrial processes rely on chemicals in dissolved form. When using powders, production must begin with a dissolution step, followed by concentration checks and potential adjustments. Lohtragon® B98 Aqueous Solution is delivered at your specified concentration, ready for direct integration into your process. Concentration levels can be tailored precisely to your operational requirements. In addition to process efficiency, aqueous solutions can support sustainability goals. Although transport emissions per ton may be higher due to water content, eliminating energy-intensive drying steps significantly reduces the overall product carbon footprint.

    Key benefits of Lohtragon® B98 Aqueous solution

    • Reduces production time & complexity 
      • Eliminates dissolution and concentration adjustment steps
    • Decrease your carbon footprint
      • No additional drying step required in manufacturing

    Frequently asked questions about this product

    What is Ammonium Citrate?

    Ammonium Citrate is the ammonium salt of citric acid (C₆H₁₇N₃O₇). It appears as a white to slightly yellow, hygroscopic crystalline solid, is highly soluble in water, and typically functions as a buffer, chelating agent, and catalyst precursor.

    What is Ammonium Citrate used for and why?

    • Chemical synthesis: acts as a pH buffer and catalyst precursor, providing stable reaction conditions in complex, multi-step processes
    • Home care: chelates hardness ions and stabilizes pH, preventing corrosion on metal surfaces
    • Surface treatment: supports even metal ion distribution, prevents scale formation, and keeps solutions stable
    • Crop care: Ferric Ammonium Citrate supplies essential iron and nitrogen, which promote robust plant growth
    • Coatings & adhesives: stabilizes emulsions and chelates trace metals, extending shelf life of formulations

    Where are our Ammonium Citrates produced?

    They are produced at our manufacturing facilities in Germany.

    What is special about our Ammonium Citrates?

    • Over 135 years of expertise in mineral and specialty salts
    • Exclusive production in Germany with strict quality control
    • Consistently low heavy metal content
    • Full batch traceability and transparent supply chain
    • Compliance with EU REACH and food-contact regulations where applicable

    What is the difference between liquid and solid Ammonium Citrate?

    Solid forms like powders or crystals are easier to store, transport with lower weight, and allow flexible preparation of different solution concentrations. Solutions, on the other hand, are ready-to-use, enable precise dosing, reduce dust exposure, and can be much more practical in continuous or large-scale processes depending on the customer’s setup.
