Description

Mono-2-(Methacryloyloxy)Ethyl Maleate is a high-purity, difunctional monomer featuring both methacrylate and maleate ester groups. This unique structure makes it a versatile and highly reactive crosslinking agent and polymer modifier, essential for creating advanced polymeric materials with tailored properties. It is a critical raw material for manufacturers in the coatings, adhesives, and specialty polymer industries seeking to enhance product performance through precise molecular design.

Application

• UV-Curable Coatings & Inks: Acts as a reactive diluent and crosslinker to improve cure speed, hardness, and chemical resistance in formulations for wood, plastic, and metal substrates.
• Dental & Biomedical Polymers: Used in the synthesis of biocompatible resins for dental composites, bone cements, and other medical devices requiring controlled polymerization and stability.
• Adhesives & Sealants: Enhances adhesion strength, thermal stability, and weatherability in structural acrylic and anaerobic adhesive systems.
• Photoresists & Electronic Materials: Serves as a key monomer in photopolymerizable resins for printed circuit boards (PCBs) and microelectronics fabrication.
• Fiber Optic Coatings: Imparts necessary durability and refractive index properties to protective secondary coatings on optical fibers.
• Modifier for Acrylic Resins: Incorporated to introduce additional crosslinking sites, improving the heat distortion temperature and mechanical properties of PMMA and other acrylics.

Quality Control

Every batch of Mono-2-(Methacryloyloxy)Ethyl Maleate is manufactured and tested under a strict quality management system. We ensure compliance with relevant industry standards and provide comprehensive Certificates of Analysis (COA) for each shipment, detailing purity, identity, and impurity profiles. Our quality assurance protocols are designed to guarantee batch-to-batch consistency, meeting the exacting requirements of advanced material synthesis.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at 2-8°C (refrigerated) or as specified on the label. This product is light-sensitive and easily oxidized; for long-term storage, consider under an inert atmosphere (e.g., nitrogen or argon) to maintain purity and inhibit premature polymerization. Keep away from heat, sparks, and open flame.
