Description

2-Propenoic Acid, 2-Methyl-, 1-Butoxyethyl Ester is a specialized acrylate ester monomer, also known as butoxyethyl methacrylate. This compound is valued for its unique combination of a methacrylate functional group and a butoxyethyl side chain, which imparts specific solubility and polymer properties. It is primarily sought by manufacturers in the polymer and coatings industries seeking to modify flexibility, adhesion, and hydrophobicity in their formulations. This product is supplied to meet the stringent quality requirements of industrial and research applications.

Application

• UV-Curable Coatings and Inks: A key reactive diluent and cross-linking agent in formulations requiring fast curing, high gloss, and chemical resistance.
• Acrylic Polymer Production: Used as a co-monomer to synthesize specialty acrylic resins, enhancing flexibility and lowering the glass transition temperature (Tg) of the final polymer.
• Adhesives and Sealants: Imparts improved adhesion to low-surface-energy substrates and enhances the tack and peel strength of pressure-sensitive and structural adhesives.
• Industrial and Automotive Coatings: Modifies the properties of solvent-borne and high-solid coatings, contributing to weatherability, durability, and flow characteristics.
• Fiber Optic Coatings: Employed in the production of primary and secondary coatings for optical fibers due to its specific refractive index and protective properties.
• Dental and Medical Polymers: Serves as a component in the synthesis of biocompatible polymers for dental composites and other medical devices.

Quality Control

Our production of 2-Butoxyethyl Methacrylate adheres to rigorous quality control protocols to ensure batch-to-batch consistency and high purity. Each lot is analyzed against stringent internal specifications, which typically include identity confirmation, assay, and control of key impurities such as inhibitor content and moisture. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to support your quality assurance processes.

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 between 15°C and 25°C. The product typically contains an inhibitor (e.g., MEHQ) to prevent polymerization during storage; please refer to the specific COA for inhibitor content and handling instructions.
