Description

1-Vinylhexyl Isobutyrate is a specialty vinyl ester monomer characterized by its unique combination of a vinyl group and a branched alkyl chain. This compound matters as a versatile building block in polymer chemistry, offering the ability to introduce both polymerizable functionality and hydrophobic, flexible side chains into copolymer systems. Industrial users in the specialty polymer, adhesive, and coating sectors need it to modify material properties such as flexibility, hydrophobicity, and glass transition temperature.

Application

• Specialty Polymer Synthesis: Serves as a co-monomer for producing tailored acrylic and vinyl acetate copolymers with enhanced flexibility and low-temperature performance.
• Pressure-Sensitive Adhesives (PSAs): Used to modify tack, peel strength, and creep resistance in adhesive formulations for tapes and labels.
• Surface Coatings & Paints: Incorporated into resin formulations to improve film formation, substrate wetting, and weatherability.
• Sealants and Caulks: Imparts permanent flexibility and adhesion to a variety of substrates, including plastics and metals.
• Crosslinking Agent: Functions as a reactive diluent and crosslinker in radiation-curable (e.g., UV/EB) coatings and inks.
• Lubricant and Plasticizer Intermediate: Acts as a precursor in the synthesis of ester-based additives for lubricants and polymers.

Quality Control

Our 1-Vinylhexyl Isobutyrate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing, including chromatography (GC/HPLC) and spectroscopic methods, to ensure high purity and consistency. Certificates of Analysis (COA) documenting identity, assay, and impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). Due to its sensitivity to oxidation, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation. Keep away from heat, sparks, open flames, and strong oxidizing agents.
