Description

Butyl 2-Methyl-2-Propenoate Polymer With 2-Hydroxyethyl 2-Methyl-2-Propenoate is a synthetic copolymer of butyl methacrylate and 2-hydroxyethyl methacrylate (HEMA). This versatile polymer is engineered to deliver a unique balance of properties, including excellent film formation, adhesion, and chemical resistance. It is a critical raw material for formulators in the coatings, adhesives, and specialty chemical industries seeking to enhance product performance and durability.

Application

• Industrial and Protective Coatings: Used as a film-forming agent and binder in high-performance coatings for metal, plastic, and wood substrates, providing durability and weather resistance.
• Adhesives and Sealants: Serves as a key component in pressure-sensitive adhesives (PSAs), structural adhesives, and sealants, improving tack, cohesion, and bond strength.
• Automotive Finishes: Incorporated into primer, basecoat, and clearcoat formulations to enhance gloss retention, scratch resistance, and environmental etch resistance.
• Textile and Leather Finishes: Applied as a coating or impregnating agent to provide water repellency, abrasion resistance, and improved hand feel to fabrics and leather goods.
• Printing Inks: Utilized in overprint varnishes and ink vehicles to improve gloss, rub resistance, and adhesion on various printing surfaces.
• Personal Care Products: Functions as a film former and fixative in hair sprays, mascara, nail polish, and sunscreens, offering water resistance and long-lasting wear.

Quality Control

Our Butyl Methacrylate - HEMA Copolymer is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistent composition, molecular weight distribution, and performance characteristics. Certificates of Analysis (COA) detailing key parameters such as monomer ratio, solids content, viscosity, and glass transition temperature (Tg) are provided with every shipment to guarantee compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C). Keep away from heat sources and open flame. Under these conditions, the product is typically stable for 24 months from the date of manufacture. For specific shelf-life information, please refer to the Certificate of Analysis.
