Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Ethenylbenzene, Methyl 2-Methyl-2-Propenoate And 1,2-Propanediol Mono(2-Methyl-2-Propenoate) is a specialized acrylic copolymer designed for high-performance applications. This multi-component polymer offers a unique balance of properties derived from its constituent monomers, including flexibility, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and advanced materials sectors seeking to enhance product durability and functionality.

Application

• Industrial and Protective Coatings: Used as a key resin binder in high-durability paints, metal coatings, and corrosion-resistant finishes.
• Adhesives and Sealants: Serves as a primary component in pressure-sensitive adhesives (PSAs), structural adhesives, and flexible sealants.
• Printing Inks: Employed in the formulation of overprint varnishes and specialty inks to improve gloss, rub resistance, and substrate adhesion.
• Plastics Modification: Acts as an impact modifier or processing aid to enhance the toughness and weatherability of compounded plastics.
• Textile and Leather Finishes: Provides durable, flexible coatings and binders for fabric coatings, non-wovens, and leather finishing.
• Automotive and Transportation: Found in interior trim coatings, underbody sealants, and other components requiring long-term environmental resistance.

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, monomer residue, viscosity, and glass transition temperature (Tg) are rigorously monitored. Certificates of Analysis (COA) documenting all relevant specifications are provided with each 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 heat sources and open flame. For long-term storage, ensure containers are sealed to prevent moisture absorption and skin formation.
