Vinylphosphonic acid is widely used in the production of polymers and copolymers, particularly for enhancing flame retardancy and adhesion properties. It is commonly incorporated into coatings, adhesives, and sealants to improve their performance on various substrates, including metals and plastics. In the textile industry, it is utilized for flame-resistant finishes on fabrics. Additionally, it serves as a key intermediate in the synthesis of specialty chemicals, such as corrosion inhibitors and scale inhibitors for water treatment applications. Its ability to form stable complexes with metal ions makes it valuable in industrial cleaning and descaling processes.
