Description

[2-Ethyl-2-[[2-[(1-Oxoallyl)Oxy]Ethoxy]Methyl]-1,3-Propanediyl]Bis(Oxy-2,1-Ethanediyl) Diacrylate CAS NO 75577-70-7 is a specialized, multi-functional acrylate monomer characterized by its unique branched molecular structure. This compound is engineered to act as a reactive diluent and cross-linking agent, significantly enhancing the performance properties of cured polymer networks. It is essential for formulators and manufacturers in the UV-curable coatings, inks, adhesives, and advanced photoresist industries who require materials that deliver high reactivity, improved flexibility, and excellent adhesion to diverse substrates.

Application

• UV-Curable Coatings & Inks: A key reactive diluent for wood, plastic, and metal coatings, offering low viscosity, fast cure speed, and enhanced surface hardness and chemical resistance.
• Photopolymer Resins & 3D Printing: Used in stereolithography (SLA) and digital light processing (DLP) resins to improve resolution, mechanical strength, and post-cure properties of printed parts.
• Adhesives & Sealants: Imparts strong adhesion and cross-link density in instant-cure acrylic and cyanoacrylate adhesive formulations.
• Electronics & Photoresists: Serves as a critical component in photo-imageable solder masks and semiconductor photoresists due to its precise reactivity under UV light.
• Fiber Optic Coatings: Contributes to the production of protective, flexible secondary coatings for optical fibers.
• Dental Composites: Employed in light-curable dental restorative materials for its biocompatibility and ability to form durable polymer matrices.
