Description

Vinyl Propionate CAS NO 105-38-4 is a versatile vinyl ester monomer characterized by its high reactivity and ability to form copolymers with a wide range of other monomers. This compound is essential for modifying polymer properties, offering benefits such as enhanced flexibility, adhesion, and weatherability in the final resin. It is a critical raw material for manufacturers in the paints & coatings, adhesives, textiles, and specialty plastics industries seeking to develop high-performance materials.

Application

• Paints & Coatings: Used as a co-monomer in the production of vinyl acetate-based emulsion polymers for interior and exterior paints, providing excellent film formation, durability, and low-temperature flexibility.
• Adhesives & Sealants: A key component in formulating pressure-sensitive adhesives (PSAs), wood glues, and construction sealants, improving tack, peel strength, and water resistance.
• Textile Finishing: Employed in the synthesis of binders and finishing agents for non-woven fabrics, carpet backing, and fabric coatings to enhance strength and handle.
• Paper Coatings: Used in barrier coatings and saturants to improve the water resistance, printability, and gloss of paper and paperboard products.
• Specialty Polymers: Serves as a reactive diluent and modifier in acrylic and vinyl copolymer systems for inks, leather finishes, and impact modifiers for plastics.
• Chemical Synthesis: Acts as an intermediate in organic synthesis for producing other esters and specialty chemicals.

Quality Control

Our Vinyl Propionate is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity. The product undergoes rigorous analytical testing, including gas chromatography (GC), to verify identity, assay, and impurity profiles. A Certificate of Analysis (COA) detailing all test results is provided with each shipment and is available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources, sparks, and open flame. Recommended storage temperature is 15-25°C (59-77°F). Due to its highly volatile and flammable nature, keep away from oxidizing agents and strong bases. Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
