Product Description

Product Description

Triethylene Glycol Diacrylate (TEGDA)
Triethylene glycol diacrylate, commonly abbreviated as TEGDA or TPEGDA, is a versatile acrylate monomer widely used in polymer chemistry and material science. Below is a detailed overview:

Basic Information

• Chemical Formula: C12H18O6
• Molar Mass: 258.27 g/mol
• CAS Number: 1680-21-3
• Synonyms:
  • TEGDA
  • Triethylene glycol bis(acrylate)
  • 2-Propenoic acid, 2,2'-(oxydi-2,1-ethanediyl) ester

Physical Properties

• Appearance: Colorless to light yellow liquid with low viscosity.
• Density: ~1.1 g/cm³ at 25°C
• Boiling Point: 266°C at 1 atm; decomposes before boiling under standard conditions.
• Melting Point: Typically a liquid at room temperature (no sharp melting point).
• Refractive Index: nD20 = 1.464
• Solubility: Soluble in common organic solvents (e.g., alcohols, esters, ketones); slightly soluble in water due to its hydrophilic ethylene glycol chains.
• Viscosity: Low (e.g., ~10-20 mPa·s at 25°C), facilitating easy processing in formulations.

Chemical Properties

• Reactivity:
  • Contains two acrylate groups (−CH=CH2COO−), making it highly reactive in free-radical polymerization (e.g., under UV light or thermal initiation).
  • Acts as a crosslinking agent in polymer networks, forming three-dimensional structures via copolymerization with other monomers (e.g., acrylates, methacrylates).
• Stability:
  • Stable under normal storage conditions but sensitive to heat, light, or radical initiators (e.g., peroxides, photoinitiators).
  • May undergo slow polymerization over time if not stored with inhibitors (e.g., MEHQ, hydroquinone monomethyl ether).

Applications

1. Polymer Chemistry & Materials Science:
   • UV-Curable Coatings/Inks: Used in printing, electronics, and automotive industries for fast-drying, durable coatings.
   • 3D Printing (SLA/DLP): As a key component in photopolymer resins for stereolithography, enabling high-resolution 3D structures.
   • Hydrogels: Crosslinked TEGDA forms hydrophilic networks for biomedical applications (e.g., drug delivery systems, tissue engineering scaffolds).
2. Composite Materials:
   • Reinforces polymers in fiberglass, carbon fiber composites, and artificial marble due to its flexibility and impact resistance.
3. Adhesives & Sealants:
   • Formulates high-strength, rapid-curing adhesives for plastics, metals, and glass.
4. Electronics:
   • Used in photoresists, solder masks, and optical waveguides for microelectronics and optoelectronics.
5. Biomedical Engineering:
   • In controlled-release systems and biodegradable materials (when modified with bio-compatible linkages).

Safety and Handling

• Hazard Class:
  • Irritant (Xi): May cause skin/eye irritation (Risk Code R36/37/38).
  • Potential sensitizer with prolonged exposure (R43).
• Safety Measures:
  • Personal Protection: Wear gloves (e.g., nitrile), safety glasses, and a lab coat. Use in a well-ventilated area or fume hood.
  • First Aid:
    • Skin/Eye Contact: Flush with water for 15 minutes; seek medical attention if irritation persists.
    • Inhalation: Move to fresh air; provide respiratory support if needed.
    • Ingestion: Rinse mouth with water; do not induce vomiting; consult a physician.
• Storage: Store in a cool, dark place in tightly sealed containers, away from heat, light, and oxidizing agents. Add inhibitors (e.g., MEHQ) to prevent premature polymerization.
• Environmental Notes:
  • Moderate toxicity to aquatic life; avoid release into water bodies.
  • Dispose of as hazardous waste following local regulations.
