Description

1,1,1-Trimethylol Ethane Triacrylate is a trifunctional acrylic monomer characterized by its high reactivity and ability to form dense, cross-linked polymer networks. This compound is essential for creating coatings, inks, and adhesives with superior hardness, chemical resistance, and fast curing properties. It is a critical raw material for formulators and manufacturers in the UV-curable resins, radiation-curing systems, and high-performance polymer industries.

Application

• UV-Curable Coatings & Inks: A key cross-linking agent for producing hard, scratch-resistant, and glossy finishes on plastics, wood, and metals.
• Photopolymer Resins: Used in 3D printing (stereolithography - SLA) and photoresists to create precise, durable 3D structures.
• Adhesives & Sealants: Imparts strong adhesion and excellent environmental resistance in acrylic-based adhesive formulations.
• Fiber Optic Coatings: Provides protective, flexible, and durable coatings for optical fibers.
• Dental & Medical Composites: Employed in light-curable composites for restorative dentistry and other medical devices.
• Electronics Encapsulation: Used in potting compounds and conformal coatings to protect electronic components.
• Overprint Varnishes: Enhances the durability and visual appeal of printed materials.
• Wood & Flooring Finishes: Delivers high-performance, fast-curing, and durable topcoats.

Quality Control

Our 1,1,1-Trimethylol Ethane Triacrylate is manufactured under a stringent quality management system. Every batch undergoes rigorous analytical testing to ensure consistent purity, performance, and stability. We provide comprehensive Certificates of Analysis (COA) with key parameters such as assay, color, acidity, and inhibitor content. Our quality commitment supports compliance with relevant global standards for industrial and specialty chemical applications.

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 light-sensitive and easily oxidized; for long-term storage, maintaining an inert atmosphere (e.g., under nitrogen) is recommended to prevent polymerization and maintain optimal quality. Keep away from heat, sparks, open flames, and incompatible materials such as strong acids and organic peroxides.
