Description

2-Propenoic Acid, Butyl Ester, Polymer With 2-Methylpropyl 2-Propenoate is a high-performance acrylic copolymer, specifically a butyl acrylate and isobutyl methacrylate copolymer, known for its excellent film-forming properties, flexibility, and adhesion. This polymer is a critical raw material valued for its ability to enhance durability, weather resistance, and gloss in formulated products. It is essential for manufacturers in the coatings, adhesives, sealants, and printing ink industries seeking to improve product performance and longevity.

Application

• Industrial and Architectural Coatings: Used as a binder in water-based and solvent-based paints to provide flexibility, adhesion, and resistance to yellowing and weathering.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in adhesive tapes and labels, offering a balance of tack, peel strength, and cohesion.
• Printing Inks: Imparts gloss, rub resistance, and binding properties to inks for packaging and publications.
• Sealants and Caulks: Enhances elasticity, adhesion to substrates, and long-term durability in construction and automotive applications.
• Textile and Leather Finishes: Used in coatings to provide a soft hand feel, water repellency, and abrasion resistance.
• Paper Coatings: Improves surface gloss, printability, and water resistance of coated paper and paperboard.
