Description

1,5-Pentanediol Dimethacrylate is a high-purity, difunctional methacrylate monomer characterized by its two reactive methacrylate groups. This compound is a critical building block in polymer chemistry, enabling the formation of cross-linked networks that impart enhanced durability, chemical resistance, and thermal stability to final materials. It is essential for formulators and manufacturers in the coatings, adhesives, and advanced polymer industries seeking to develop high-performance, cross-linkable resin systems.

Application

• As a cross-linking agent in the production of high-performance, thermosetting acrylic resins and coatings.
• A key monomer in UV-curable inks, coatings, and adhesives, contributing to rapid curing and excellent film properties.
• Used in the manufacture of dental composites and restorative materials for improved mechanical strength and wear resistance.
• Employed as a co-monomer in the synthesis of impact-resistant polymers and engineering plastics.
• Essential in the formulation of fiber-reinforced plastics (FRP) and gel coats for marine and automotive applications.
• Utilized in the production of optical lenses and components where clarity and dimensional stability are required.
• Serves as a reactive diluent and modifier in various specialty polymer systems to adjust viscosity and final polymer properties.

Quality Control

Our 1,5-Pentanediol Dimethacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay by GC/HPLC, identity confirmation (IR), and impurity profiling, to ensure it meets stringent specifications for polymer-grade applications. Certificates of Analysis (COA) documenting purity, color, acid value, and inhibitor content are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15-25°C (59-77°F). This product is easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to preserve monomer reactivity and prevent premature polymerization. Keep away from heat, sparks, and open flame.
