Description

Triethylene Glycol Diacrylate is a difunctional acrylic ester monomer characterized by its high reactivity and ability to form cross-linked polymer networks. This compound is essential for creating durable, chemically resistant, and flexible polymeric materials with tailored properties. It is a critical raw material for manufacturers in the coatings, adhesives, inks, and advanced resin industries seeking to enhance product performance.

Application

• UV-Curable Coatings & Inks: A key component in formulations for wood, plastic, and metal coatings, as well as printing inks, providing fast cure speeds, excellent adhesion, and high gloss.
• Adhesives & Sealants: Used in the production of acrylic-based structural adhesives and pressure-sensitive adhesives (PSAs) to improve bond strength and environmental resistance.
• Photopolymer Resins: Serves as a cross-linking agent in resins for 3D printing (stereolithography - SLA), photoresists, and dental composites, enabling precise, high-resolution curing.
• Fiber Optic Coatings: Employed in the primary and secondary coating layers to protect optical fibers, offering flexibility and protection against moisture and mechanical stress.
• Overprint Varnishes: Enhances the scratch resistance, chemical resistance, and visual appeal of printed packaging and labels.
• Reactive Diluent: Acts as a viscosity modifier and reactive component in various radiation-curable systems without compromising final film properties.

Quality Control

Our Triethylene Glycol Diacrylate is manufactured under a stringent quality management system. Every batch undergoes comprehensive analytical testing to ensure it meets precise specifications for purity, color, and inhibitor content. Certificates of Analysis (COA) are provided with each shipment, documenting key parameters such as assay, acid value, and water content to guarantee consistent performance and reliability in your formulations.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at temperatures between 15-25°C (59-77°F). This product is easily oxidized and should be stored under an inert atmosphere (e.g., nitrogen) when in partially used containers to prevent premature polymerization. Keep away from heat, sparks, open flames, and incompatible materials such as strong oxidizers and bases.
