Description

2-Propenoic Acid, Ethyl Ester, Polymer With Ethenylbenzene is a high-performance copolymer, widely recognized as an acrylic-styrene resin, valued for its excellent balance of hardness, clarity, and weatherability. This material is engineered to provide durable, protective coatings and robust, transparent plastic components. It is a critical raw material for manufacturers in the paints & coatings, adhesives, plastics compounding, and industrial finishes sectors seeking to enhance product performance.

Application

• Paints & Industrial Coatings: Used as a binder in water-based and solvent-based formulations to improve gloss, adhesion, and resistance to yellowing and environmental factors.
• Adhesives and Sealants: Serves as a key polymer component to provide strong bonding strength, flexibility, and durability in pressure-sensitive and construction adhesives.
• Plastics Modification: Employed as an impact modifier and clarifier in transparent plastic compounds, enhancing processability and end-product toughness.
• Printing Inks: Acts as a resin vehicle to improve ink gloss, rub resistance, and substrate adhesion in packaging and publication inks.
• Textile and Leather Finishes: Utilized in coatings to provide a protective, flexible, and glossy finish on fabrics and synthetic leather.
• Paper Coatings: Incorporated into coatings to enhance surface smoothness, printability, and water resistance of high-quality paper products.

Quality Control

Our 2-Propenoic Acid, Ethyl Ester, Polymer With Ethenylbenzene is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing to ensure consistent properties such as molecular weight distribution, monomer content, viscosity, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting full 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, ensure the container is sealed to prevent moisture absorption and contamination.
