Description

Dipentaerythritol Pentaacrylate is a high-functionality, multi-acrylate monomer characterized by its five reactive acrylate groups. This molecular structure is critical for creating densely cross-linked polymer networks, delivering exceptional hardness, chemical resistance, and thermal stability to final products. It is an essential raw material for formulators in the UV/EB-curable coatings, inks, adhesives, and photoresist industries seeking to enhance performance properties.

Application

• UV-Curable Coatings & Inks: A key crosslinker for hard, scratch-resistant, and glossy finishes on wood, plastics, and metal.
• Photopolymer Printing Plates: Provides high resolution and durability in flexographic and letterpress plate production.
• Electronics & Photoresists: Used in solder masks and photo-imageable dielectric films for printed circuit boards (PCBs).
• Optical Fiber Coatings: Imparts protective, low-shrinkage secondary coatings to ensure fiber integrity.
• Adhesives & Sealants: Enhances bond strength and environmental resistance in instant-cure structural adhesives.
• 3D Printing Resins: Serves as a reactive diluent and crosslinker in stereolithography (SLA) resins for high-detail models.

Quality Control

Our Dipentaerythritol Pentaacrylate is manufactured under a strict quality management system. Every batch undergoes rigorous analytical testing to ensure consistency and meets high-purity specifications for reactive monomers. A comprehensive Certificate of Analysis (COA) detailing assay, purity, color, acidity, and inhibitor content is provided with each shipment.

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/59-77°F). Keep away from heat, sparks, and open flame. This product is light-sensitive (store away from light) and compatible with strong acid/organic solvent materials. For long-term storage, under an inert atmosphere such as nitrogen is recommended to prevent premature polymerization.
