Description

2-Ethylbutyl Methacrylate is a high-purity, monofunctional methacrylate ester monomer. This compound is valued for its ability to impart specific properties such as low glass transition temperature (Tg), flexibility, and hydrophobicity to polymer chains. It is primarily sought after by manufacturers in the coatings, adhesives, sealants, and elastomers (CASE) industries, as well as for the production of specialty acrylic resins and polymer additives.

Application

• Acrylic Resin Modifier: Used to introduce flexibility and improve low-temperature performance in acrylic and vinyl-acrylic copolymer resins.
• Radiation-Curable Coatings & Inks: Serves as a reactive diluent and property modifier in UV/EB-curable formulations for wood, plastic, and metal coatings.
• Pressure-Sensitive Adhesives (PSAs): Imparts tack and enhances adhesion properties in acrylic-based PSA tapes and labels.
• Sealants & Caulks: Incorporated to improve elasticity, weatherability, and adhesion in construction and industrial sealants.
• Lubricant & Fuel Additives: Acts as a precursor for polymeric additives that improve viscosity index and dispersancy.
• Textile & Leather Finishes: Used in polymers applied as softeners, water repellents, or finishing agents.

Quality Control

Our 2-Ethylbutyl Methacrylate is manufactured under a stringent quality management system. Each batch undergoes comprehensive analytical testing, including gas chromatography (GC) for purity and identity confirmation, to ensure it meets exacting specifications. Certificates of Analysis (COA) documenting purity, assay, and key physical properties are provided with every shipment and are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area away from heat sources and incompatible materials such as strong acids and oxidizing agents. Recommended storage temperature is 15-25°C. Keep container tightly sealed when not in use to prevent moisture absorption and polymerization.
