Description

2-Propenoic Acid, Butyl Ester, Polymer With Ethenylbenzene And 2-Ethylhexyl 2-Propenoate is a high-performance acrylic copolymer designed to deliver exceptional durability and versatility in demanding industrial applications. This terpolymer combines the properties of butyl acrylate, styrene, and 2-ethylhexyl acrylate to offer a balanced profile of flexibility, adhesion, and weather resistance. It is a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product performance and longevity.

Application

This versatile acrylic terpolymer is engineered for a wide range of industrial applications where film formation, binding, and protective properties are paramount.

• Architectural and Industrial Coatings: Used as a binder in exterior paints, primers, and topcoats to provide excellent UV resistance, water repellency, and durability.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in adhesive tapes and labels, offering a balance of tack, peel strength, and cohesion.
• Construction Sealants and Caulks: Imparts flexibility, adhesion to various substrates, and long-term weatherability in sealant formulations.
• Textile and Leather Finishes: Applied as a coating or binder to provide a soft hand feel, water resistance, and improved abrasion resistance.
• Paper and Packaging Coatings: Enhances surface gloss, printability, and water resistance of paper and cardboard products.
• Industrial Binders: Acts as a binding agent in non-woven fabrics, fiber mats, and other composite materials.
