Description

Dipropylene Glycol Dimethacrylate is a high-purity, difunctional methacrylate monomer characterized by its excellent crosslinking properties and low volatility. This compound is a critical raw material for creating durable, high-performance polymer networks with enhanced chemical resistance and mechanical strength. It is essential for manufacturers in the coatings, adhesives, and advanced composites industries seeking to improve product longevity and performance under demanding conditions.

Application

• UV-Curable Coatings & Inks: A key reactive diluent and crosslinker for formulations requiring fast cure speeds, high gloss, and superior surface hardness.
• Dental & Medical Polymers: Used in the production of dental composites, crown & bridge materials, and bone cements for its biocompatibility and strength.
• Adhesives & Sealants: Imparts strong adhesion, flexibility, and environmental resistance to acrylic-based structural and industrial adhesives.
• Fiberglass Reinforced Plastics (FRP): Serves as a crosslinking agent in gel coats and resin systems for marine, automotive, and construction applications.
• Photopolymer Printing Plates: A vital component in plates for flexographic and letterpress printing, offering precise image reproduction and durability.
• Acrylic Sheet & Casting Resins: Enhances the thermal stability and mechanical properties of cast acrylic sheets and molded resin parts.

Quality Control

Our Dipropylene Glycol Dimethacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including gas chromatography (GC) for purity and identity verification, to ensure it meets precise specifications for reactive monomer applications. Certificates of Analysis (COA) are provided with each shipment to guarantee traceability, consistency, and compliance with your formulation requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at 15-25°C. Keep away from heat, sparks, and open flame. This material is light-sensitive (store away from light) and compatible with strong acid/organic solvent materials. For long-term storage under an inert atmosphere (nitrogen) is recommended to prevent premature polymerization.
