Description

2-Propenoic acid, 2-methyl-, eicosyl ester, polymer with 1-ethenyl-2-pyrrolidinone, hexadecyl 2-methyl-2-propenoate, isodecyl 2-methyl-2-propenoate, methyl 2-methyl-2-propenoate and octadecyl 2-methyl-2-propenoate is a high-performance, multi-component acrylic copolymer designed for advanced material science applications. This specialized polymer offers a unique balance of properties derived from its carefully selected monomer composition, including long-chain alkyl acrylates for hydrophobicity and flexibility, and vinylpyrrolidone for enhanced adhesion and compatibility. It is a critical raw material for formulators in the coatings, adhesives, and personal care industries seeking to engineer products with specific film-forming, binding, and surface-modifying characteristics. The compound is supplied under CAS No. 68171-46-0.

Application

• Industrial and Protective Coatings: Acts as a key film-forming agent and binder in solvent-based or high-solid coatings, providing durability, water resistance, and adhesion to various substrates.
• Pressure-Sensitive Adhesives (PSAs): Used in the formulation of tapes and labels, contributing to tack, peel strength, and cohesive strength due to its tunable polymer backbone.
• Personal Care & Cosmetic Products: Serves as a film former and fixative in hair styling products (sprays, gels, mousses) and as a water-resistant agent in makeup formulations.
• Textile and Leather Finishing: Imparts water repellency, softness, and improved handle to fabrics and leather goods as a component of finishing agents.
• Printing Inks: Functions as a resin component to enhance gloss, rub resistance, and adhesion of inks on non-porous surfaces like plastics and metals.
• Specialty Additives: Utilized as a dispersant, rheology modifier, or compatibilizer in various composite and polymer blend systems.

Quality Control

Our production of this specialty acrylic copolymer adheres to strict quality management systems to ensure batch-to-batch consistency and performance reliability. Key parameters such as monomer composition, molecular weight distribution, viscosity, and residual monomer content are rigorously controlled. A comprehensive Certificate of Analysis (COA) detailing specific test results is provided with each shipment to support your quality assurance protocols.

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, an inert atmosphere (nitrogen) is recommended to prevent oxidation and maintain product stability.
