Phenoxypolyethylene Glycol Acrylate (n=approx. 2) from TCI is a monofunctional acrylate monomer. It has a short ethylene glycol chain, about two units on average, capped with a phenoxy group. Polymer and formulation laboratories use it as a component in polymerizable systems such as UV-curable resins, adhesives, inks and coatings. The product is stabilized with MEHQ to prevent unwanted polymerization during storage, so its quality is kept until use. Researchers can add it to experimental formulations as a reactive building block.

The monomer is chosen because it combines an aromatic phenoxy group with a flexible ethylene glycol segment. The aromatic part tends to raise the refractive index and improve affinity toward aromatic substrates or formulation components. The glycol segment helps keep the polymer chain flexible. Because it is a monofunctional acrylate, it does not form crosslinks on its own. For this reason it is often used as a reactive diluent: it lowers formulation viscosity and still becomes part of the final polymer network after curing. Formulators can use this balance of properties to adjust both handling and final material behavior.

In Indonesia, this material is relevant to research laboratories working on coatings, inks, adhesives, dental materials and printing technologies. University polymer chemistry groups, industrial R&D centers and quality control laboratories can use it to study photopolymerization, screen reactive diluents, or fine-tune optical and mechanical properties in experimental formulations. Because it comes from TCI, laboratories get a consistent research-grade reagent for comparative studies and method development. It is useful wherever UV-curable or radically polymerizable systems are developed or evaluated.

Related TCI products

  • UV-curable resin formulation: as a monofunctional acrylate, it takes part in radical photopolymerization and becomes part of the cured polymer network without forming crosslinks on its own.
  • Reactive diluent studies: researchers use it to lower formulation viscosity while keeping the diluent reactive, so it ends up built into the final cured material instead of evaporating.
  • Adhesive development: its aromatic phenoxy group can improve affinity toward aromatic substrates and formulation components, and its glycol segment adds chain flexibility to the adhesive layer.
  • Ink and coating research: formulators use it to adjust flow and curing behavior in printing inks and protective coatings that are cured by UV light or other radical initiation methods.
  • Dental and printing material research: its mix of aromatic and flexible segments makes it useful for exploring refractive index and flexibility in dental resins and in photopolymers used for printing.

Storage stabilized with MEHQ; store according to the TCI label and SDS recommendations

Keep this monomer in its original, tightly closed TCI container, away from direct sunlight, heat sources, UV light and polymerization initiators. Follow the storage conditions on the label and in the Safety Data Sheet. MEHQ-stabilized acrylates should not be stored under fully inert conditions unless the supplier instructs otherwise, because the inhibitor usually needs some oxygen to work. Acrylates can irritate the skin and may cause sensitization. Handle the material in a well-ventilated area or fume hood, and wear chemical-resistant gloves, safety glasses and a lab coat. Avoid contact with skin and eyes, and dispose of waste according to local regulations.
