Description

Di(Trimethylolpropane) Tetraacrylate is a high-functionality, tetra-functional acrylate monomer that serves as a critical crosslinking agent in radiation-curable formulations. Its molecular structure provides a dense network upon polymerization, delivering exceptional hardness, chemical resistance, and durability to the final product. This monomer is essential for manufacturers in the coatings, inks, and adhesives industries seeking to enhance the performance and speed of their UV/EB curing processes.

Application

• UV-Curable Coatings: A key component in high-performance wood, plastic, and metal coatings requiring superior scratch, abrasion, and solvent resistance.
• Printing Inks: Used in fast-curing lithographic, screen, and flexographic inks to improve adhesion and film hardness on various substrates.
• Optical Fiber Coatings: Imparts necessary protective and mechanical properties as a primary or secondary coating material.
• Electronics: Employed in photoresists, solder masks, and conformal coatings for printed circuit boards (PCBs).
• Adhesives & Sealants: Enhances the cohesive strength and cure speed of industrial and specialty adhesives.
• 3D Printing Resins: Acts as a reactive diluent and crosslinker in stereolithography (SLA) and digital light processing (DLP) resins for high-resolution, tough parts.

Quality Control

Our Di(Trimethylolpropane) Tetraacrylate is manufactured under a stringent quality management system. Each batch undergoes rigorous analytical testing, including assay, impurity profiling, and physical property verification, to ensure consistency and compliance with industry standards. A comprehensive Certificate of Analysis (COA) detailing purity, inhibitor content, and other critical parameters is provided with every shipment.

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 (store under inert atmosphere) and is light-sensitive (store away from light). Keep away from heat, sparks, and open flame. For long-term storage, maintaining an inert gas blanket (e.g., nitrogen) is recommended to prevent premature polymerization.
