Description

2-Propenoic acid, 2-methyl-, dodecyl ester, polymer with N-3-(dimethylamino)propyl-2-methyl-2-propenamide, eicosyl 2-methyl-2-propenoate, hexadecyl 2-methyl-2-propenoate, octadecyl 2-methyl-2-propenoate and tetradecyl 2-methyl-2-propenoate is a high-performance, multi-component acrylic copolymer designed for advanced material science applications. This specialized polymer offers a unique combination of properties derived from its carefully engineered structure, including long-chain alkyl esters and a dimethylaminopropyl functional group. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical industries seeking to enhance product durability, rheology, and surface interaction. The compound with CAS number 147358-21-2 represents a sophisticated solution for demanding industrial applications.

Application

• Industrial and Protective Coatings: Acts as a key film-forming agent and rheology modifier in high-performance paints, varnishes, and metal coatings, improving gloss, weather resistance, and application properties.
• Pressure-Sensitive Adhesives (PSAs): Used in the formulation of tapes, labels, and graphic films to balance tack, peel strength, and cohesive strength, particularly where enhanced temperature resistance is required.
• Ink and Overprint Varnishes: Imparts excellent adhesion, rub resistance, and gloss in printing inks and protective coatings for packaging and publications.
• Textile and Leather Finishes: Serves as a durable binder and finishing agent to provide water repellency, soft hand feel, and abrasion resistance to fabrics and leather goods.
• Personal Care and Cosmetic Products: Functions as a film former and fixative in hair styling products, mascara, and nail polish, offering long-lasting hold and water resistance.
• Additive for Plastics and Composites: Utilized as a processing aid, impact modifier, or compatibilizer to improve the mechanical properties and surface characteristics of polymer blends.

Quality Control

Our production of this advanced acrylic copolymer adheres to strict quality management systems, ensuring batch-to-batch consistency and performance reliability. Each lot undergoes comprehensive analysis, including determination of solid content, viscosity, amine value, and residual monomer levels. We provide a detailed Certificate of Analysis (COA) with every shipment, documenting key parameters to support your quality assurance protocols. While produced under cGMP-like conditions for industrial use, specifications can be aligned with specific customer requirements and regional regulatory frameworks.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at a controlled room temperature (typically 15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for at least 24 months from the date of manufacture. Prolonged exposure to elevated temperatures or freezing should be avoided to prevent changes in consistency or performance.
