Description

Vinyl Behenate is a high-purity, long-chain vinyl ester derived from behenic acid, serving as a versatile monomer and chemical intermediate. This compound is valued for its ability to introduce hydrophobic, long alkyl chains into polymer backbones, significantly modifying material properties. It is primarily sought by R&D chemists and production engineers in the polymer, specialty chemical, and advanced materials sectors for applications requiring tailored surface characteristics and internal plasticization.

Application

• Polymer Modification: Used as a comonomer in the synthesis of specialty polymers, including polyvinyl esters and copolymers, to enhance flexibility, hydrophobicity, and low-temperature performance.
• Surface Coatings & Resins: Incorporated into formulations for paints, varnishes, and industrial coatings to improve water resistance, durability, and film-forming properties.
• Internal Plasticizer: Acts as a reactive plasticizer within polymer matrices, reducing migration issues compared to external additives and improving long-term material stability.
• Lubricant & Grease Additive: Serves as a precursor or intermediate in the production of high-performance synthetic lubricants and grease thickeners.
• Adhesive & Sealant Formulations: Enhances the adhesion and moisture resistance of pressure-sensitive adhesives and construction sealants.
• Chemical Synthesis Intermediate: Employed in organic synthesis for creating surfactants, emulsifiers, and other functional chemicals leveraging its long alkyl chain and reactive vinyl group.
