Description

n-Butyl Methacrylate, Acrylonitrile, n-Butyl Acrylate, Methacrylic Acid Polymer is a specialized acrylic copolymer designed to deliver a unique balance of properties for advanced material formulations. This polymer is engineered to provide enhanced chemical resistance, durability, and adhesion characteristics, making it a critical component for high-performance applications. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for specialty plastics and textile finishing.

Application

• Industrial and Protective Coatings: Used as a binder or resin modifier to improve weatherability, chemical resistance, and film toughness.
• Pressure-Sensitive Adhesives (PSAs): Imparts excellent tack, peel strength, and cohesive balance for labels and tapes.
• Textile and Leather Finishes: Provides durable, flexible, and water-resistant coatings for fabrics and synthetic leather.
• Plastic Modifiers and Impact Improvers: Enhances the impact strength and processability of engineering plastics and PVC blends.
• Sealants and Caulks: Contributes to long-term flexibility, adhesion, and resistance to environmental degradation.
• Printing Inks: Used in formulations requiring fast setting, rub resistance, and good substrate adhesion.

Quality Control

Our n-Butyl Methacrylate, Acrylonitrile, n-Butyl Acrylate, Methacrylic Acid Polymer is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent performance, including measurement of molecular weight distribution, monomer content, acid value, and glass transition temperature (Tg). Certificates of Analysis (COA) detailing all 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 (nitrogen) is recommended to prevent oxidation and maintain product stability.
