Description

2-Butenedioic Acid (Z)-, Polymer With 1,3-Butadiene, Ethenylbenzene And 2-Methyl- 2-Propenamide is a high-performance, multi-component copolymer designed for advanced material applications. This engineered polymer combines the functional groups of maleic acid, butadiene, styrene, and acrylamide to deliver a unique balance of adhesion, film-forming properties, and chemical resistance. It is essential for formulators and manufacturers seeking to enhance the durability and performance of coatings, adhesives, and specialty composites. Key industries that rely on this polymer include paints and coatings, construction materials, and textile finishing.

Application

• Industrial Coatings Binder: Used as a key film-forming agent and adhesion promoter in water-based and solvent-based industrial paints, primers, and metal coatings.
• Adhesive & Sealant Formulations: Imparts strong bonding strength and flexibility in construction adhesives, pressure-sensitive adhesives (PSAs), and sealants.
• Textile & Leather Finishing: Serves as a durable polymer binder and crosslinking agent in fabric coatings, leather finishes, and non-woven binders.
• Paper & Packaging Coatings: Enhances water resistance, printability, and surface strength in paper coatings and packaging materials.
• Construction Additive: Incorporated into cementitious mixtures, mortars, and tile adhesives to improve workability, water retention, and final mechanical properties.
• Specialty Composite Materials: Acts as a matrix or compatibilizer in fiber-reinforced plastics and other composite systems.
