Description

2-Propenicacid 2-Hydroxyethyl Ester Polymer With 2-Methylpropyl 2-Propenoate is a high-performance copolymer of hydroxyethyl methacrylate (HEMA) and isobutyl methacrylate (IBMA). This material is engineered to deliver a unique balance of properties, including excellent film-forming capability, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and specialty polymer industries seeking to enhance product durability and performance. The compound with CAS number 92004-96-1 is supplied as a consistent, high-quality material to meet stringent industrial requirements.

Application

• Industrial Coatings: Used as a key binder or additive in high-performance coatings for metal, plastic, and wood substrates, providing enhanced weatherability, gloss, and chemical resistance.
• Adhesives and Sealants: Serves as a film-forming polymer in pressure-sensitive adhesives (PSAs), structural adhesives, and sealants, improving tack, peel strength, and flexibility.
• Printing Inks: Incorporated into overprint varnishes and specialty inks to improve adhesion, rub resistance, and surface gloss on various packaging materials.
• Personal Care Products: Utilized in nail polish, hair sprays, and other cosmetic formulations as a film-forming agent to provide long-lasting wear and water resistance.
• Textile and Leather Finishes: Applied in coatings for textiles and leather to impart water repellency, durability, and a soft hand feel.
• Optical Materials: Can be used in the formulation of contact lenses, optical adhesives, and transparent films due to its clarity and compatibility with other monomers.

Quality Control

Our HEMA-IBMA copolymer is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency in molecular weight distribution, monomer content, and key physical properties. We provide comprehensive Certificates of Analysis (COA) with each shipment, detailing specifications such as solids content, viscosity, glass transition temperature (Tg), and residual monomer levels. Our quality commitment ensures the material meets the performance needs of advanced industrial applications.

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. Under these conditions, the product is stable for extended periods. For long-term storage, an inert atmosphere (e.g., nitrogen) is recommended to prevent potential oxidation.
