Description

Acrylonitriledimethylaminoethyl Methacrylate Copolymer is a synthetic cationic polymer derived from acrylonitrile and dimethylaminoethyl methacrylate. This copolymer is valued for its unique combination of properties, including excellent film-forming ability, adhesion, and cationic charge density, making it a versatile functional material. It is primarily utilized in industries such as water treatment, paper manufacturing, and personal care, where its flocculating, retention, and conditioning capabilities are essential for process efficiency and product performance.

Application

• Water Treatment: Acts as a highly effective cationic flocculant and coagulant aid for the clarification of industrial wastewater and potable water.
• Paper Industry: Used as a retention and drainage aid to improve fiber and filler retention on the paper machine wire, enhancing paper quality and production speed.
• Personal Care & Cosmetics: Functions as a film-forming agent, conditioning polymer, and viscosity modifier in hair care products (e.g., hair sprays, mousses) and skincare formulations.
• Textile Processing: Serves as a dye-fixing agent and antistatic agent to improve color fastness and handle of synthetic fibers.
• Adhesives & Sealants: Imparts improved adhesion, cohesion, and rheological properties to various adhesive systems.
• Coatings: Utilized as a binder and dispersant in specialty coatings to enhance substrate adhesion and film integrity.

Quality Control

Our Acrylonitriledimethylaminoethyl Methacrylate Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including assessment of cationic charge density, viscosity, solids content, and residual monomer levels. A comprehensive Certificate of Analysis (COA) documenting these specifications is provided with every shipment to guarantee compliance with your technical requirements.

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); containers must be kept tightly sealed after opening to prevent moisture absorption, which can affect product performance.
