Description

4-Methacryloxyethyl Trimellitic Anhydride is a high-purity, reactive monomer featuring both methacrylate and cyclic anhydride functionalities. This dual functionality is critical for creating strong, durable covalent bonds in advanced polymer matrices, directly addressing the need for enhanced material performance and longevity. It is an essential raw material for manufacturers in the dental materials, specialty adhesives, and advanced coating industries seeking to improve product adhesion, mechanical strength, and biocompatibility.

Application

• Dental Adhesive & Cement Formulations: A key component in self-etching dental adhesives and resin cements, where it bonds to both tooth dentin/enamel and composite restorative materials.
• Denture Base & Repair Resins: Used to enhance the adhesion between acrylic denture bases and repair materials or artificial teeth.
• Bone Cement & Orthopedic Applications: Incorporated into acrylic bone cements to improve mechanical interlocking at the bone-implant interface.
• Specialty Adhesives: Serves as an adhesion-promoting monomer in high-performance structural adhesives for metals, ceramics, and composites.
• Coating & Encapsulation Resins: Imparts improved adhesion and corrosion resistance in protective coatings and electronic encapsulation materials.
• Crosslinking Agent: Functions as a crosslinker in polymer systems to increase thermal stability, chemical resistance, and mechanical properties.
• Surface Modification: Used to graft polymer chains onto inorganic surfaces (e.g., glass, silica) for tailored surface properties.

Quality Control

Our 4-Methacryloxyethyl Trimellitic Anhydride is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including HPLC for purity and identity confirmation, to ensure it meets the high standards required for sensitive applications like dental and medical materials. A comprehensive Certificate of Analysis (COA) detailing purity, assay, and impurity profiles is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at 2-8°C (refrigerated) or as specified on the label. This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed under a dry inert atmosphere (e.g., nitrogen) after opening to prevent hydrolysis of the anhydride group.
