Description

Methyl Methacrylate, Polymer With Methacrylic Acid, Butyl Methacrylate And 2-Ethylhexyl Acrylate is a specialized multi-monomer copolymer designed to deliver a unique balance of properties. This engineered polymer is significant for its ability to provide tailored performance in demanding coating and adhesive formulations. It is primarily needed by manufacturers in the paints & coatings, pressure-sensitive adhesives, industrial finishes, and textile treatment sectors seeking enhanced flexibility, adhesion, and durability.

Application

• Architectural and Industrial Coatings: Used as a film-forming agent to improve flexibility, weather resistance, and adhesion to various substrates.
• Pressure-Sensitive Adhesives (PSAs): Serves as a key component in tapes and labels, offering a balance of tack, peel strength, and cohesion.
• Textile Finishes and Binders: Imparts durability, water resistance, and soft hand feel to fabrics and non-wovens.
• Printing Inks and Overprint Varnishes: Enhances gloss, rub resistance, and substrate adhesion.
• Leather and Paper Coatings: Provides protective, flexible films that improve surface quality and longevity.
• Sealants and Caulks: Contributes to elasticity, adhesion, and long-term performance in construction applications.

Quality Control

Our acrylic copolymer products undergo rigorous quality testing to ensure batch-to-batch consistency and compliance with industry standards. Key parameters such as solid content, viscosity, acid value, glass transition temperature (Tg), and molecular weight distribution are strictly monitored. Certificates of Analysis (COA) documenting these 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, well-ventilated area at room temperature (typically 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 skin formation or gelation. Ensure containers are kept tightly sealed when not in use to prevent moisture absorption and solvent loss.
