Description

Butanedioic Acid, Methylene-, Polymer With Butyl 2-Propenoate, Ethyl 2-Propenoate, 2-Propenamide And 2-Propenenitrile is a specialized acrylic copolymer designed for high-performance industrial applications. This multi-component polymer offers a unique balance of properties derived from its constituent monomers, making it a valuable material for demanding formulations. It is primarily utilized in sectors requiring advanced binding, film-forming, or rheological modification capabilities, such as coatings, adhesives, and construction materials.

Application

• Industrial Coatings Binder: Used as a film-forming agent in protective and decorative coatings for metal, wood, and plastic substrates, providing durability and chemical resistance.
• Adhesive and Sealant Formulations: Serves as a key polymer component in pressure-sensitive adhesives (PSAs), construction sealants, and assembly adhesives, enhancing tack, cohesion, and bond strength.
• Textile and Non-Woven Binders: Applied as a binder for fiber bonding in non-woven fabrics, textile finishing, and pigment printing, improving wash fastness and hand feel.
• Paper Coating and Sizing: Functions as a strengthening agent and coating polymer to improve paper surface properties, printability, and water resistance.
• Leather Finishing: Used in topcoat formulations for leather to provide a flexible, protective, and aesthetically pleasing finish.
• Construction Additive: Incorporated into cementitious mixes, tile adhesives, and renders as a redispersible polymer powder to improve flexibility, adhesion, and workability.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems. Each batch is tested for critical parameters including solid content, viscosity, pH, glass transition temperature (Tg), and mechanical properties to ensure batch-to-batch consistency and performance reliability. Certificates of Analysis (COA) documenting these specifications are available upon request. We support compliance with relevant industry standards for raw materials used in formulated products.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed when not in use to prevent moisture absorption, which may affect product performance. Keep away from incompatible materials such as strong oxidizing agents.
