Description

Tetraacrylic Acid, Tetraester With 2,2'-[Oxybis(Methylene)]Bis[2-(Hydroxymethyl)Propane-1,3-Diol] Dipropionate is a specialized multifunctional acrylate ester monomer. This compound is valued for its ability to introduce multiple polymerizable acrylate groups into a system, enabling the formation of highly cross-linked, durable polymer networks. It is primarily sought by formulators and researchers in the advanced coatings, photoresists, and specialty adhesives industries who require materials for high-performance, radiation-curable applications.

Application

• UV/EB Curable Coatings and Inks: Acts as a cross-linking agent to enhance hardness, chemical resistance, and cure speed in formulations for wood, plastic, and metal substrates.
• Photoresists and Microelectronics: Serves as a key monomer in the synthesis of photopolymerizable resins for semiconductor patterning and printed circuit board (PCB) manufacturing.
• Dental and Medical Composites: Used in the formulation of light-curable restorative materials and biocompatible polymer matrices.
• Specialty Adhesives and Sealants: Imparts strong adhesion and thermal stability to high-performance structural and optical adhesives.
• 3D Printing Resins (SLA/DLP): A component in resin formulations to improve resolution, mechanical strength, and post-cure properties of printed parts.
• Fiber Optic Coatings: Contributes to the production of protective, radiation-cured coatings with excellent clarity and environmental durability.
