Description

2-Propenoic acid, 2-methyl-, butyl ester, polymer with 2-(dimethylamino)ethyl 2-methyl-2-propenoate, ethenylbenzene, 2-ethylhexyl 2-propenoate and methyl 2-methyl-2-propenoate CAS NO 119012-34-9 is a specialized acrylic copolymer designed for advanced performance in demanding coating and adhesive formulations. This multi-monomer polymer offers a unique balance of properties, including excellent film formation, adhesion, and chemical resistance, making it a critical component for high-performance industrial applications. It is primarily utilized by formulators in the paints & coatings, pressure-sensitive adhesives, and industrial sealants sectors seeking to enhance product durability and functionality.

Application

• Industrial and Protective Coatings: Used as a key resin binder in metal primers, machinery enamels, and anti-corrosive coatings, providing strong adhesion and resistance to chemicals and solvents.
• Pressure-Sensitive Adhesives (PSAs): Serves as a high-performance polymer base for tapes, labels, and graphic films, offering tunable tack, peel strength, and holding power.
• Textile and Leather Finishes: Employed in coatings and binders to impart water resistance, flexibility, and improved handle to fabrics and synthetic leather.
• Printing Inks: Functions as a pigment grinding resin and film-former in overprint varnishes and specialty inks, enhancing gloss, rub resistance, and substrate adhesion.
• Caulks and Sealants: Acts as a primary polymer in flexible sealants for construction and automotive applications, contributing to weatherability and long-term elasticity.
• Paper and Packaging Coatings: Used in barrier coatings and saturants to improve water and grease resistance for food packaging and industrial paper products.

Quality Control

Our production of this specialty acrylic copolymer adheres to strict quality management protocols to ensure batch-to-batch consistency and performance reliability. Key parameters such as molecular weight distribution, solids content, viscosity, and monomer residue are rigorously monitored. Certificates of Analysis (COA) detailing all relevant specifications are provided with each shipment to support your quality assurance and regulatory compliance needs.

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 properly sealed to prevent skin formation or changes in viscosity.
