Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With 1,3-Butadiene, Ethenylbenzene And 2-Hydroxyethyl 2-Propenoate (9Ci) is a specialized multi-component acrylic copolymer designed to deliver a unique balance of properties. This polymer is engineered to provide excellent adhesion, flexibility, and durability, making it a critical raw material for high-performance coatings and adhesives. It is primarily utilized by formulators in the paint, industrial coating, pressure-sensitive adhesive, and construction sealant industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, machinery enamels, and anti-corrosive paints for its strong adhesion and chemical resistance.
• Architectural Paints: Imparts durability, scrub resistance, and weatherability to exterior and interior wall paints.
• Pressure-Sensitive Adhesives (PSAs): Serves as a base polymer for labels, tapes, and graphic films, offering a balance of tack, peel strength, and cohesion.
• Construction Sealants and Caulks: Provides flexibility, adhesion to diverse substrates, and long-term elasticity in joint sealants.
• Textile and Leather Finishes: Used in coatings and binders to improve surface feel, abrasion resistance, and water repellency.
• Paper and Packaging Coatings: Enhances gloss, printability, and barrier properties of coated papers and paperboard.
