Description

Maleic Acid, Mono-2-Acryloxyethyl Ester is a specialized bifunctional monomer featuring both a maleate and an acrylate group within a single molecule. This unique structure makes it a highly reactive and versatile crosslinking agent and polymer modifier. It is essential for manufacturers seeking to enhance the performance characteristics of polymers, such as adhesion, hardness, and chemical resistance. This product is primarily utilized in the production of advanced coatings, adhesives, UV-curable resins, and specialty polymers.

Application

• As a reactive diluent and crosslinker in UV-curable inks, coatings, and adhesives.
• Key monomer for synthesizing high-performance acrylic and polyester resins with improved film properties.
• Used in the production of dental composites and restorative materials for enhanced durability.
• Component in fiberglass-reinforced plastics (FRP) and gel coats to improve mechanical strength.
• Crosslinking agent for water-based polymer dispersions used in industrial coatings.
• Intermediate in the synthesis of specialty chemicals and pharmaceutical agents.
• Modifier for pressure-sensitive adhesives (PSAs) to adjust tack and peel strength.

Quality Control

Our production of Maleic Acid, Mono-2-Acryloxyethyl Ester adheres to stringent quality management protocols. Every batch is analyzed to ensure it meets precise chemical and physical specifications, including purity, identity, and absence of critical impurities. Certificates of Analysis (COA) documenting these results are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at room temperature (15-25°C). Keep away from heat, sparks, and open flame. Due to its acrylic and maleate functional groups, it is recommended to store under an inert atmosphere if long-term storage is anticipated to prevent premature polymerization.
