Description

Poly(Butadiene/Maleic Acid) CAS NO 28265-35-2 is a synthetic copolymer derived from butadiene and maleic acid, known for its reactive anhydride and carboxylic acid functionalities. This versatile polymer is valued for its ability to act as a reactive intermediate, cross-linking agent, and modifier, enhancing the performance of various industrial materials. It is essential for manufacturers in the coatings, adhesives, and polymer modification sectors seeking to improve adhesion, toughness, and chemical resistance in their formulations.

Application

• Coatings & Paints: Used as a binder or cross-linking agent to improve film hardness, adhesion to metal substrates, and corrosion resistance.
• Adhesives & Sealants: Serves as a key component in structural and pressure-sensitive adhesives, enhancing tack, cohesion, and bond strength.
• Polymer Modification: Acts as a compatibilizer or impact modifier in polymer blends and composites, particularly for engineering plastics and elastomers.
• Paper & Textile Sizing: Functions as a sizing agent to improve water resistance, strength, and printability of paper and textile fibers.
• Oilfield Chemicals: Employed as a fluid loss additive or viscosifier in drilling mud formulations.
• Chelating Agent: Utilized in water treatment and detergent formulations for its metal ion sequestering properties.

Quality Control

Our Poly(Butadiene/Maleic Acid) is manufactured under a strict quality management system. Each batch undergoes rigorous testing for key parameters including acid value, molecular weight distribution, and residual monomer content to ensure consistency and performance. Certificates of Analysis (COA) are provided with every shipment and are available upon request.

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 material is hygroscopic (moisture-sensitive); containers must be kept tightly sealed to prevent absorption of atmospheric moisture, which can affect product performance.
