Description

Dipentaerythritol Hexaacrylate is a high-functionality, multi-acrylate monomer that serves as a critical building block for advanced polymer networks. Its six reactive acrylate groups enable the formation of highly cross-linked, durable, and high-performance coatings, inks, and adhesives. This product is essential for formulators in the UV/EB-curable resins, photopolymers, and specialty coatings industries seeking to enhance hardness, chemical resistance, and cure speed.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent for high-gloss, scratch-resistant wood, plastic, and metal coatings, as well as fast-curing printing inks.
• Photoresists & Photopolymers: Used in the formulation of solder masks, lithographic resists, and 3D printing (stereolithography) resins due to its high reactivity and resolution.
• Adhesives & Sealants: Imparts excellent adhesion and cohesive strength in instant-cure acrylic adhesives and anaerobic sealants.
• Fiber Optic Coatings: Provides protective, durable secondary coatings for optical fibers, ensuring signal integrity and mechanical protection.
• Dental & Medical Materials: A component in light-curable composites and restorative materials requiring biocompatibility and high strength.
• Electronics Encapsulation: Used in potting compounds and conformal coatings to protect electronic components, offering excellent moisture and chemical barrier properties.

Quality Control

Our Dipentaerythritol Hexaacrylate is manufactured under a strict quality management system. Each batch undergoes rigorous analytical testing to ensure consistency, purity, and performance. Certificates of Analysis (COA) documenting key parameters such as assay, color, acidity, 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). Keep away from heat, sparks, and open flame. To prevent premature polymerization, ensure the product is stored with the recommended inhibitor content and avoid contamination.
