Description

2-(2-Butoxyethoxy)Ethyl Methacrylate is a high-purity, specialty methacrylate monomer featuring a unique oligo(ethylene glycol) butyl ether side chain. This molecular structure is critical for imparting flexibility, hydrophilicity, and excellent solvating properties to the resulting polymers. It is an essential building block for formulators and polymer chemists in advanced material sectors. Key industries that utilize this monomer include coatings, adhesives, photoresists, and specialty polymer manufacturing.

Application

• UV-Curable Coatings & Inks: As a reactive diluent and modifier to enhance flexibility, adhesion, and surface wetting properties.
• Pressure-Sensitive Adhesives (PSAs): To adjust the viscoelastic properties, tack, and peel strength of acrylic adhesive formulations.
• Photoresists & Electronic Chemicals: Used in the synthesis of polymers for photoresist applications in semiconductor and display manufacturing.
• Hydrophilic Polymer Modifier: To introduce hydrophilic character and improve compatibility in water-based or hybrid coating systems.
• Crosslinking Agent: Serves as a co-monomer to introduce crosslinkable sites for enhanced chemical and abrasion resistance.
• Specialty Acrylic Resins: For the production of tailored acrylic copolymers with specific solubility and Tg profiles.
