Description

2-Propenoic Acid, 2-Methyl-, Methyl Ester, Polymer With Butyl 2-Propenoate, Ethenylbenzene And 2-Propenyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This specialized polymer offers a unique balance of properties, including excellent adhesion, chemical resistance, and film-forming characteristics. It is a critical raw material for formulators in the coatings, adhesives, and sealants industries seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a key binder in high-durability paints, metal primers, and anti-corrosion coatings for automotive, marine, and structural steel applications.
• Pressure-Sensitive Adhesives (PSAs): Serves as a primary component in the formulation of tapes, labels, and graphic films, providing balanced tack, peel, and shear strength.
• Construction Sealants and Caulks: Imparts flexibility, weather resistance, and strong adhesion to substrates like concrete, glass, and metals in building and infrastructure projects.
• Textile and Leather Finishes: Employed in coatings and binders to provide water repellency, abrasion resistance, and improved hand feel.
• Printing Inks: Used in overprint varnishes and ink formulations to enhance gloss, rub resistance, and substrate adhesion.
• Plastic and Composite Modification: Acts as a impact modifier or compatibilizer to improve the toughness and processing of polymer blends.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as solid content, viscosity, glass transition temperature (Tg), and acid value are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all specifications is provided with each shipment 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, ensure containers are sealed to prevent skin formation or changes in viscosity.
