Description

Boric Acid Tri-n-Hexadecyl Ester is a high-purity, long-chain alkyl borate ester with the CAS number 2665-11-4. This specialty chemical serves as a versatile intermediate and functional additive, offering unique properties derived from its hydrophobic cetyl (hexadecyl) chains. It is particularly valuable for industries requiring advanced lubricants, polymer stabilizers, or hydrophobic surface treatments. Key markets include specialty chemical manufacturing, advanced materials, and high-performance lubricant formulation.

Application

• As a high-performance lubricant additive and friction modifier in synthetic oils and greases.
• As a hydrophobic agent and water repellent in surface coatings and textile treatments.
• As a plasticizer and stabilizer in polymer and resin formulations to enhance processing and properties.
• As a key chemical intermediate for synthesizing more complex boron-containing compounds.
• As a corrosion inhibitor in protective coatings and metalworking fluids.
• In the research and development of advanced materials, such as liquid crystals and nanostructured composites.
