Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Butyl 2-Propenoate, Ethenylbenzene, 1,2-Propanediol Mono(2-Methyl-2-Propenoate) And 2-Propenoic Acid is a specialized multi-component acrylic copolymer designed for high-performance applications. This engineered polymer delivers a critical balance of properties, including excellent adhesion, chemical resistance, and film-forming characteristics. It is essential for industrial formulators seeking to enhance the durability and functionality of coatings, adhesives, and sealants across demanding environments.

Application

• Industrial and Protective Coatings: Used as a key binder in metal primers, automotive underbody coatings, and corrosion-resistant finishes.
• Adhesive Formulations: Serves as a primary component in high-strength structural adhesives, pressure-sensitive adhesives (PSAs), and laminating agents.
• Sealants and Caulks: Provides flexibility, adhesion, and weather resistance in construction and automotive sealant formulations.
• Plastic and Composite Modification: Acts as a compatibilizer or impact modifier to improve the properties of polymer blends and composites.
• Textile and Leather Finishes: Imparts water repellency, abrasion resistance, and a durable hand feel to treated fabrics and leathers.
• Printing Inks: Utilized in overprint varnishes and specialty inks to enhance gloss, rub resistance, and substrate adhesion.

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 viscosity, solids content, acid value, and glass transition temperature (Tg) are rigorously monitored. A comprehensive Certificate of Analysis (COA) detailing all relevant specifications is provided with every 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 strong acids and organic solvents. For long-term storage, ensure containers are sealed to prevent skin formation or moisture absorption.
