Description

Sorbitol Pentaacrylate CAS NO 53123-67-4 is a high-functionality, multi-acrylate monomer derived from sorbitol. This compound is valued for its ability to form highly cross-linked, durable polymer networks with excellent hardness and chemical resistance upon curing. It is primarily sought after by formulators in the UV/EB-curable coatings, inks, adhesives, and photopolymer resin industries, where it acts as a key reactive diluent and cross-linking agent to enhance final product performance.

Application

• UV-Curable Coatings & Inks: A critical cross-linker for wood, plastic, and metal coatings, as well as graphic arts and printing inks, providing fast cure speeds and superior surface hardness.
• Photopolymer Resins: Used in stereolithography (SLA) and other 3D printing resins to create rigid, high-resolution models and prototypes.
• Adhesives & Sealants: Imparts strong adhesion and durability in radiation-curable adhesive formulations.
• Fiber Optic Coatings: Contributes to the protective, fast-curing secondary coatings on optical fibers.
• Electronics: Employed in solder masks and conformal coatings for printed circuit boards (PCBs) due to its excellent electrical insulation and chemical resistance.
• Dental & Medical Materials: Serves as a component in light-curable composites and restorative materials.
