Description

Pentaerythritol Dimethacrylate is a high-purity, multi-functional methacrylate monomer characterized by its four reactive methacrylate groups. This chemical structure is critical for creating highly cross-linked polymer networks, delivering exceptional hardness, chemical resistance, and thermal stability in the final cured materials. It is an essential raw material for manufacturers in the coatings, adhesives, and advanced composites industries seeking to enhance the performance characteristics of their products.

Application

• UV-Curable Coatings & Inks: A key component in formulations for hard, scratch-resistant, and glossy finishes on plastics, metals, and wood.
• Dental Composites & Restorative Materials: Used as a cross-linking agent to provide high strength, low shrinkage, and excellent durability in dental applications.
• Optical Fiber Coatings: Imparts essential protective and mechanical properties to the primary and secondary coatings of optical fibers.
• Adhesives & Sealants: Enhances bond strength, cure speed, and environmental resistance in anaerobic, acrylic, and structural adhesives.
• Printing Plates & Photopolymers: Serves as a cross-linker in liquid photopolymer resins for flexographic and letterpress printing plates.
• Composite Materials: Used as a matrix resin or modifier in fiber-reinforced plastics (FRP) and gel coats for improved mechanical performance.
• Acrylic Sheet & Casting Resins: Modifies properties such as hardness and heat distortion temperature in cast acrylic products.

Quality Control

Our Pentaerythritol Dimethacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing, including Gas Chromatography (GC) and Infrared Spectroscopy (IR), to ensure high purity and consistent performance. Certificates of Analysis (COA) documenting key parameters such as assay, color, 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 room temperature (15-25°C). Keep away from heat, sparks, and open flame. To maintain optimal quality and prevent premature polymerization, ensure the inhibitor content is monitored during prolonged storage.
