Description

2-Propenoic Acid, 2-Methyl-, Butyl Ester, Polymer With Butyl 2-Propenoate, Ethenylbenzene And Methyl 2-Methyl-2-Propenoate is a high-performance acrylic copolymer designed to deliver exceptional durability and versatility in demanding formulations. This product is engineered to provide superior film formation, adhesion, and resistance to environmental factors, making it a critical component for advanced industrial coatings and adhesives. Manufacturers in the paints & coatings, pressure-sensitive adhesives, and specialty polymer industries rely on this tailored polymer for its consistent quality and performance.

Application

• Industrial and Architectural Coatings: Used as a key binder to enhance weatherability, gloss retention, and chemical resistance in metal, wood, and plastic coatings.
• Pressure-Sensitive Adhesives (PSAs): Provides excellent tack, peel strength, and cohesive balance for labels, tapes, and graphic films.
• Automotive Refinish and OEM Coatings: Imparts durability, flexibility, and a high-quality finish for automotive topcoats and primers.
• Industrial Adhesives and Sealants: Serves as a primary component in formulations requiring strong bonding, flexibility, and resistance to aging.
• Plastic and Leather Finishes: Used to create protective and decorative coatings with good adhesion to non-porous substrates.
• Ink and Overprint Varnishes: Contributes to fast drying, rub resistance, and high gloss in graphic arts and packaging applications.

Quality Control

Our production of this acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Every lot is tested against key parameters including solid content, viscosity, glass transition temperature (Tg), and residual monomer levels. Certificates of Analysis (COA) documenting full 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, 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 skin formation or changes in viscosity.
