Description

2-Propenoic Acid, 2-Methyl-, Dodecyl Ester, Polymer With Methyl 2-Methyl-2-Propenoate And Octadecyl 2-Methyl-2-Propenoate is a high-performance, multi-component acrylic copolymer designed to deliver exceptional film-forming and surface-modifying properties. This specialized polymer is engineered to provide durability, water resistance, and compatibility in demanding formulations. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty chemical industries seeking to enhance product performance and longevity.

Application

• Industrial and Protective Coatings: Acts as a key film-forming agent in solvent-based and high-solids coatings, providing excellent gloss, hardness, and chemical resistance for metal, wood, and plastic substrates.
• Pressure-Sensitive Adhesives (PSAs): Used to formulate adhesives with balanced tack, peel strength, and shear resistance for tapes, labels, and graphic films.
• Printing Inks: Imparts rub resistance, gloss, and pigment binding properties in flexographic and gravure inks for packaging applications.
• Textile and Leather Finishes: Serves as a durable topcoat or binder to provide water repellency, soft hand feel, and abrasion resistance.
• Caulks and Sealants: Enhances flexibility, adhesion, and weatherability in construction and automotive sealant formulations.
• Plastic Additives: Functions as a processing aid or impact modifier to improve the surface characteristics and mechanical properties of polymer compounds.

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) detailing all relevant specifications are provided with every 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/59-77°F). Keep away from heat, sparks, and open flame. Ensure containers are kept tightly sealed when not in use to prevent solvent loss or contamination.
