Description

2-Methyl-2-Propenoic Acid Polymer With Butyl 2-Methyl-2-Propenoate, Butyl 2-Propenoate, Ethenylbenzene And Octadecyl 2-Methyl-2-Propenoate CAS NO 111325-21-4 is a specialized multi-component copolymer designed to deliver a unique balance of properties for advanced material formulations. This engineered polymer is valued for its ability to modify surface characteristics, enhance durability, and provide tailored performance in demanding environments. It is a critical raw material for manufacturers in the coatings, adhesives, sealants, and specialty plastics industries seeking to improve product performance and processing.

Application

• High-Performance Industrial Coatings: Acts as a key film-forming agent and modifier to enhance gloss, weather resistance, and chemical durability in protective paints and varnishes.
• Pressure-Sensitive Adhesives (PSAs): Used to adjust tack, peel strength, and shear resistance in label, tape, and graphic film adhesives.
• Plastic Additives & Modifiers: Functions as a processing aid, impact modifier, or compatibilizer to improve the mechanical properties and surface finish of polymer blends.
• Printing Inks: Imparts rub resistance, adhesion to substrates, and controlled viscosity in solvent-based and UV-curable ink systems.
• Textile & Leather Finishes: Provides water repellency, soft hand feel, and abrasion resistance in fabric coatings and leather treatments.
• Sealants & Caulks: Contributes to flexibility, adhesion, and long-term weatherability in construction and automotive sealant formulations.

Quality Control

Our production of this specialty 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, glass transition temperature (Tg), and solid content are rigorously monitored. Certificates of Analysis (COA) detailing specific lot specifications are available upon request, supporting compliance with relevant industry standards for raw materials.

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, consider under an inert atmosphere to prevent oxidation. Ensure containers are kept sealed when not in use to prevent moisture absorption and maintain product integrity.
