Description

Dipropylene Glycol Monoacrylate is a monofunctional acrylic ester monomer characterized by its reactive acrylate group and a propylene glycol-based chain. This chemical structure is crucial for its role as a versatile building block in polymer synthesis, offering a balance of reactivity, flexibility, and hydrophilicity to final products. It is essential for formulators and manufacturers in the coatings, adhesives, and specialty polymers industries seeking to modify the physical and performance characteristics of their materials.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinking agent in formulations for wood, plastic, and metal coatings, contributing to fast cure speeds and enhanced film flexibility.
• Adhesives & Sealants: Used in the production of pressure-sensitive adhesives (PSAs) and anaerobic sealants, improving adhesion and environmental resistance.
• Acrylic Resin Modification: Serves as a co-monomer to tailor the properties of acrylic polymers, impacting glass transition temperature (Tg), solubility, and weatherability.
• Fiber Optic Coatings: Employed in the matrix for primary and secondary coatings on optical fibers due to its curing properties and low shrinkage.
• Dental & Medical Polymers: Utilized in light-curable composites and restorative materials where controlled polymerization and biocompatibility are required.
• Printing Plate Resins: A component in photopolymer resins for flexographic and letterpress printing plates.

Quality Control

Our Dipropylene Glycol Monoacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency and meets high-purity standards suitable for industrial and specialty applications. Certificates of Analysis (COA) detailing assay, purity, and impurity profiles are provided with every shipment to guarantee traceability and compliance with your specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at room temperature (15-25°C/59-77°F). This product is light-sensitive and easily oxidized; it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize polymerization. Keep away from heat, sparks, open flames, and strong oxidizing agents.
