Description

2-Propenoic Acid, Polymer With Ethenylbenzene, 2-Ethylhexyl 2-Propenoate And 2-Hydroxyethyl 2-Propenoate is a specialized acrylic copolymer designed to deliver a unique balance of properties for advanced coating and adhesive formulations. This multi-component polymer is engineered to provide exceptional durability, adhesion, and flexibility, making it a critical raw material for high-performance applications. Industrial buyers in the coatings, adhesives, sealants, and elastomers (CASE) sectors rely on this polymer to enhance product performance and meet stringent technical specifications.

Application

• Industrial and Protective Coatings: Used as a key binder in high-performance coatings for metal, plastic, and wood substrates, offering excellent weather resistance, gloss retention, and chemical resistance.
• Pressure-Sensitive Adhesives (PSAs): Provides the necessary tack, peel strength, and shear resistance for labels, tapes, and graphic films.
• Architectural Paints: Enhances the scrub resistance, adhesion, and durability of interior and exterior decorative paints.
• Textile and Leather Finishes: Serves as a finishing agent to improve the feel, durability, and water repellency of fabrics and leather goods.
• Printing Inks: Imparts adhesion, rub resistance, and gloss in formulations for various printing processes.
• Caulks and Sealants: Contributes to flexibility, adhesion, and long-term weatherability in construction and automotive sealants.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Each lot is tested against key parameters including solids content, viscosity, pH, and glass transition temperature (Tg). Certificates of Analysis (COA) documenting these specifications are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from strong acids and organic solvents. Do not freeze. Under these conditions, the product is typically stable for 12 months from the date of manufacture.
