Description

2-Propenoic Acid, 2-Methyl-, Polymer With Ethenylbenzene, Ethyl 2-Propenoate, Methyl 2-Methyl-2-Propenoate And 1,2-Propanediol Mono(2-Methyl-2-Propenoate) is a specialized multi-component acrylic copolymer designed for high-performance applications. This engineered 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 advanced materials sectors 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.
• Adhesives and Sealants: Serves as a primary resin component in pressure-sensitive adhesives (PSAs), construction sealants, and laminating adhesives, providing strong bonding and flexibility.
• Printing Inks: Employed in the formulation of overprint varnishes and specialty inks to improve gloss, rub resistance, and substrate adhesion.
• Textile and Leather Finishes: Acts as a coating agent to provide water repellency, soft hand feel, and improved abrasion resistance to fabrics and leather goods.
• Plastic Modifiers and Additives: Utilized to modify the impact strength, surface properties, and processability of engineering plastics and composites.

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 molecular weight distribution, acid value, glass transition temperature (Tg), and solids content are rigorously monitored. Certificates of Analysis (COA) documenting full specifications are available for 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 moisture absorption and skin formation.
