Description

2-Propenoic Acid, Polymer With 1,3-Butadiene, Butyl 2-Propenoate, And Ethenylbenzene is a high-performance, multi-component polymer designed for demanding industrial applications. This specialized copolymer offers a unique balance of properties derived from its acrylic, butadiene, butyl acrylate, and styrene monomers, making it a versatile material for formulation engineers. It is primarily sought by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries seeking to enhance product durability, flexibility, and adhesion.

Application

• Industrial and Protective Coatings: Used as a film-forming agent or binder in paints and varnishes, providing excellent weatherability, chemical resistance, and adhesion to various substrates.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in adhesive tapes and labels, offering a balance of tack, peel strength, and cohesive strength.
• Sealants and Caulks: Imparts flexibility, elongation, and durability to construction and automotive sealants, ensuring long-term performance.
• Textile and Fiber Binders: Acts as a binder for non-woven fabrics and fiber treatments, improving strength and hand feel.
• Paper Coating and Sizing: Enhances the surface strength, printability, and water resistance of paper and paperboard products.
• Impact Modifier for Plastics: Can be used as an additive to improve the toughness and impact resistance of brittle polymer matrices.

Quality Control

Our polymer products are manufactured under a strict quality management system to ensure batch-to-batch consistency and performance. Each lot is tested against key parameters including solids content, viscosity, pH, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance protocols.

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). Keep away from heat sources and open flame. For long-term storage, an inert atmosphere (e.g., nitrogen) is recommended to prevent oxidation and maintain product integrity.
