Description

2-Propenoic Acid, Polymer With Butyl 2-Propenoate, Ethenylbenzene And (1-Methylethenyl)Benzene is a high-performance, multi-component acrylic copolymer designed for demanding industrial applications. This polymer offers a unique balance of properties derived from its constituent monomers, including film-forming capability, adhesion, and chemical resistance. It is a critical raw material for manufacturers in the coatings, adhesives, and construction materials sectors seeking to enhance product durability and performance.

Application

• Industrial and Protective Coatings: Used as a primary binder or additive in metal, wood, and concrete coatings to improve weatherability, gloss, and corrosion resistance.
• Adhesives and Sealants: Serves as a key polymer component in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives, providing strong bonding and flexibility.
• Textile and Non-Woven Binders: Applied as a durable binder for fabric coatings, non-woven materials, and fiber processing to enhance strength and handleability.
• Paper and Packaging Coatings: Utilized in surface sizing and coating formulations to improve printability, water resistance, and barrier properties.
• Architectural Paints: Functions as a resin in interior and exterior decorative paints, contributing to scrub resistance, stain release, and film integrity.
• Specialty Inks: Incorporated into formulations for flexographic and gravure inks to achieve desired adhesion and drying characteristics on various substrates.

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 solids content, viscosity, pH, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) documenting these specifications are available for every shipment upon request, supporting your quality assurance and regulatory compliance needs.

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 properly sealed to prevent skin formation or changes in viscosity.
