Description

Isocyanuric Acid Tris(2-Acryloyloxyethyl) Ester is a specialized trifunctional acrylate monomer, a key building block for creating high-performance, cross-linked polymer networks. This compound is valued for its ability to impart enhanced durability, chemical resistance, and thermal stability to final materials. It is primarily sought by formulators and manufacturers in the advanced coatings, photoresists, and specialty adhesives industries.

Application

• UV-Curable Coatings & Inks: Serves as a cross-linking agent to create hard, scratch-resistant, and glossy finishes for wood, plastic, and metal substrates.
• Photoresists & Electronic Materials: Used in the formulation of photo-patternable resins for printed circuit boards (PCBs) and semiconductor packaging due to its high reactivity and resolution.
• Dental & Medical Composites: Functions as a co-monomer in light-curable restorative materials, providing strong mechanical properties and biocompatibility.
• Specialty Adhesives & Sealants: Enhances the bond strength, flexibility, and environmental resistance of acrylic-based adhesive systems.
• Fiber Optic Coatings: Contributes to the production of protective, secondary coatings that safeguard optical fibers from moisture and mechanical stress.
• 3D Printing Resins (SLA/DLP): A critical component in formulating high-resolution, tough, and heat-resistant resins for additive manufacturing.

Quality Control

Our Isocyanuric Acid Tris(2-Acryloyloxyethyl) Ester is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and color determination, to ensure it meets stringent specifications for high-purity monomer applications. Certificates of Analysis (COA) detailing purity, identity, and key physical parameters are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at temperatures between 15-25°C (59-77°F). Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and organic solvents. For long-term storage, consider under an inert atmosphere to prevent premature polymerization.
