Description

Trimethylolpropane Propoxylate Triacrylate is a multifunctional acrylate monomer characterized by its high reactivity and low viscosity. This compound is a crucial building block in the formulation of advanced polymers, offering excellent crosslinking density and fast cure rates under UV or electron beam radiation. It is primarily utilized by manufacturers in the coatings, inks, adhesives, and photoresist industries seeking to enhance the durability, chemical resistance, and performance of their end products.

Application

• UV-Curable Coatings & Inks: A key component in formulations for wood, plastic, and metal coatings, as well as graphic arts and printing inks, providing rapid curing and a hard, scratch-resistant finish.
• Adhesives & Sealants: Used in the production of high-performance, instant-cure adhesives for optical, electronic, and industrial assembly applications.
• Photopolymer Resists: Serves as a critical monomer in photoresists for printed circuit board (PCB) manufacturing and other microelectronic applications.
• Dental & Medical Materials: Employed in light-curable composites and restorative materials due to its biocompatibility and rapid polymerization.
• 3D Printing Resins: A functional ingredient in stereolithography (SLA) and digital light processing (DLP) resins, contributing to precise, high-resolution prints.
• Fiber Optic Coatings: Used in coatings that protect optical fibers, offering excellent environmental and mechanical protection.

Quality Control

Our Trimethylolpropane Propoxylate Triacrylate is manufactured under a strict quality management system. Each batch undergoes comprehensive analytical testing, including assay, impurity profiling, and physical property verification, to ensure it meets precise specifications and consistent performance for your formulations. A Certificate of Analysis (COA) is provided with every shipment, documenting key parameters such as purity, color, acid value, and inhibitor content.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at temperatures between 15°C and 25°C (59°F and 77°F). Keep away from heat, sparks, and open flame. To prevent premature polymerization, ensure the product is stored with the recommended inhibitor content intact.
