Description

Butyl Acrylate-Methyl Methacrylate Polymers are a versatile class of acrylic copolymers known for their excellent film-forming properties, durability, and chemical resistance. These polymers are engineered to provide a critical balance of flexibility, adhesion, and weatherability, making them indispensable in high-performance coating and adhesive formulations. Key industries that rely on this material include paints & coatings, pressure-sensitive adhesives, textiles, and construction materials.

Application

• Architectural and Industrial Coatings: Used as a primary binder or modifier to enhance flexibility, water resistance, and gloss in exterior paints, metal coatings, and wood finishes.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in tapes and labels, providing excellent tack, peel strength, and aging stability.
• Textile and Leather Finishes: Applied as a coating or binder to impart water repellency, softness, and durability to fabrics and synthetic leather.
• Construction Materials: Incorporated into caulks, sealants, and cement modifiers to improve adhesion, elasticity, and resistance to environmental stress.
• Printing Inks: Used in overprint varnishes and ink formulations to enhance gloss, rub resistance, and drying properties.
• Paper Coatings: Improves surface strength, printability, and barrier properties of packaging and specialty papers.

Quality Control

Our Butyl Acrylate-Methyl Methacrylate Polymers are manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing to ensure consistent performance, including measurement of molecular weight distribution, monomer content, glass transition temperature (Tg), and viscosity. A Certificate of Analysis (COA) detailing all relevant 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). 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 stability.
