Description

2-Propenoic Acid, Dodecyl Ester, Polymer With Ethenyl Acetate CAS NO 79426-47-4 is a high-performance copolymer of lauryl acrylate and vinyl acetate. This specialized polymer is engineered to deliver excellent film-forming properties, flexibility, and water resistance, making it a critical component in advanced coating and adhesive formulations. It is primarily sought after by manufacturers in the paints & coatings, adhesives & sealants, and textile finishing industries for its ability to enhance product durability and performance.

Application

• Architectural and Industrial Coatings: Used as a film-forming agent to improve flexibility, water repellency, and durability in water-based paints and varnishes.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack, peel strength, and cohesive balance in label and tape adhesives.
• Textile and Leather Finishes: Serves as a soft, hydrophobic binder for coatings that provide water resistance and a soft hand feel.
• Paper and Packaging Coatings: Enhances surface gloss, printability, and moisture barrier properties.
• Caulks and Sealants: Contributes to elasticity, adhesion, and long-term weatherability in construction sealants.
• Ink Formulations: Used as a resin to improve adhesion and rub resistance in flexographic and gravure inks.
