Description

2-Propenoic Acid, 2-Methyl-, Polymer With Butyl 2-Propenoate, 2-(Dimethylamino)Ethyl 2-Methyl-2-Propenoate, Ethenylbenzene And Methyl 2-Methyl-2-Propenoate is a specialized multi-component acrylic copolymer designed for advanced performance applications. This engineered polymer offers a unique balance of properties derived from its constituent monomers, making it a critical raw material for formulating high-value industrial products. It is primarily utilized by manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product durability, adhesion, and functional characteristics.

Application

• Industrial and Protective Coatings: Used as a key binder or film-forming agent in high-performance paints, metal primers, and corrosion-resistant coatings, providing excellent adhesion and weatherability.
• Pressure-Sensitive Adhesives (PSAs): Serves as a base polymer for tapes and labels, offering tunable tack, peel strength, and cohesion due to its multi-monomer composition.
• Textile and Leather Finishes: Applied as a coating or finishing agent to impart water resistance, durability, and improved handle to fabrics and leather goods.
• Paper and Packaging Coatings: Enhances the surface strength, printability, and barrier properties of paperboard and packaging materials.
• Architectural Paints: Formulated into interior and exterior paints to improve scrub resistance, color retention, and overall film integrity.
• Specialty Inks: Utilized in the formulation of printing inks to achieve specific rheological properties, adhesion to various substrates, and fast drying times.

Quality Control

Our production of this acrylic copolymer adheres to stringent quality management protocols to ensure batch-to-batch consistency and performance reliability. Each lot is characterized for critical parameters including solid content, viscosity, glass transition temperature (Tg), acid value, and amine value. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing specifications and test results. Our quality system is designed to support formulations requiring compliance with various industrial and regulatory standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C / 59-77°F). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed when not in use to prevent absorption of atmospheric moisture, which can affect product properties. Keep away from incompatible materials such as strong oxidizing agents.
