Description

Glycerol 1,2-Dimethacrylate (CAS NO 101525-90-0) is a high-purity, difunctional methacrylate monomer characterized by its two reactive double bonds. This compound is valued for its ability to form highly cross-linked polymer networks, imparting superior hardness, chemical resistance, and thermal stability to final materials. It is an essential raw material for manufacturers in the dental materials, optical lens, adhesive, and specialty coating industries seeking to enhance product performance.

Application

• Dental Composites & Restorative Materials: A key cross-linking agent in resin-based composites, providing the necessary mechanical strength, wear resistance, and low polymerization shrinkage.
• Optical Lenses & Hard Coatings: Used in the formulation of scratch-resistant, high-refractive-index coatings for eyeglasses, safety lenses, and optical components.
• Adhesives & Sealants: Imparts excellent adhesion and durability in UV-curable or anaerobic adhesive systems for industrial assembly.
• Printing Inks & Photoresists: Serves as a reactive diluent and cross-linker in radiation-curable inks for high-performance printing and in photopolymer formulations for electronics.
• Biomedical & Hydrogel Polymers: Utilized in the synthesis of controlled-release drug delivery systems and biocompatible hydrogel matrices due to its polymerizable functionality.
