Description

11-Phosphonoundecyl Acrylate is a specialized organophosphorus monomer featuring a long alkyl chain terminated with both an acrylate and a phosphonate functional group. This unique bifunctional structure makes it a critical intermediate for synthesizing advanced polymeric materials with exceptional adhesion, corrosion resistance, and surface modification properties. It is essential for R&D and production in industries focused on high-performance coatings, metal treatment, and advanced composite materials.

Application

• Metal Surface Treatment & Pretreatment: As a key component in formulations for corrosion-resistant coatings and conversion coatings on steel, aluminum, and other metals.
• Adhesion Promoters & Coupling Agents: To enhance the bonding between inorganic substrates (metals, glass, minerals) and organic polymer matrices in coatings, adhesives, and composites.
• Scale & Corrosion Inhibitors: For use in industrial water treatment systems, cooling towers, and oilfield applications to prevent mineral scale formation and metal corrosion.
• Functional Monomer for Specialty Polymers: Incorporated into acrylic, vinyl, or other copolymer systems to impart phosphonate functionality for improved hydrophilicity, chelation, or flame retardancy.
• Dental & Biomedical Materials: As a building block for adhesives and restorative materials where strong bonding to tooth enamel or other substrates is required.
• Textile & Fiber Modification: To create flame-retardant or soil-release finishes on fabrics and nonwovens.
