1. Paints & Coatings

• Corrosion Resistance: It can be used in the production of anticorrosive coatings for metals, helping to protect them from rust and environmental degradation by enhancing the bonding between the metal surface and the coating.
• Surface Treatment: Ammonium fluoborate may also be used in the preparation of surfaces before painting, especially in metal coatings, where it can improve adhesion and durability.

2. Sealants & Adhesives

• • Bonding Agent: Due to its ability to modify the surface properties of metals and other materials, ammonium fluoborate may be used in adhesives and sealants to improve bonding strength, particularly in industrial and construction applications.

3. Chemical Synthesis

• Fluorine Source: It can be used as a fluorinating agent in organic synthesis, where the introduction of fluoride is required in the formation of various fluorine-containing compounds.
• Intermediate in Chemical Reactions: Ammonium fluoborate may serve as a reagent or intermediate in the production of other chemicals, especially in reactions requiring the fluoride ion or silicon-fluoride interactions.

4. Metal Treatment

• Etching Agent: It is used in the etching of metals, particularly in the electronics and aerospace industries. The fluoride component helps to modify metal surfaces for improved bonding or processing.
• Flux in Soldering: Ammonium fluoborate can be employed as a flux in soldering applications to remove oxides and enhance the metal's ability to bond during the soldering process.
