Description

Vinylamine/Vinyl Alcohol Copolymer CAS NO 29499-22-7 is a versatile synthetic polymer composed of vinylamine and vinyl alcohol monomer units, offering a unique combination of cationic and hydrophilic properties. This dual functionality makes it an exceptional material for applications requiring charge modification, adhesion promotion, and film formation. It is particularly valuable for industries such as water treatment, paper manufacturing, and specialty coatings, where its ability to interact with various substrates is critical. The copolymer's structure provides tunable performance characteristics to meet specific formulation needs.

Application

• Flocculant and Retention Aid in Papermaking: Enhances fiber retention, drainage, and improves paper strength and quality.
• Wastewater Treatment Agent: Acts as an effective cationic coagulant for the removal of suspended solids and organic matter.
• Surface Sizing and Coating Binder: Improves surface strength, printability, and ink receptivity of paper and board.
• Adhesive and Binder Formulations: Used in specialty adhesives, non-wovens, and construction materials for its binding and film-forming properties.
• Personal Care and Cosmetic Products: Functions as a film former, hair fixative, and conditioning agent in hair sprays, gels, and creams.
• Textile Processing Aid: Serves as a dye-fixing agent, antistatic agent, and finishing chemical to improve fabric handle and performance.

Quality Control

Our Vinylamine/Vinyl Alcohol Copolymer is manufactured under a strict quality management system. Each batch is tested to ensure consistent performance, including parameters such as amine content, degree of hydrolysis, viscosity, and solids content. A Certificate of Analysis (COA) documenting these results is provided with every shipment to guarantee compliance with your specifications and industry standards.

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 and caking. Keep away from strong oxidizing agents.
