Aronix® is the brand name for special acrylic monomers and oligomers developed by Toagosei Co., Ltd. Aronix® on the market includes special acrylates, urethane acrylates, and polyester acrylates.

  • Special Acrylates: Generally, this type has low viscosity, low irritation and excellent light curing. Therefore, these acrylates are effective in lowering the viscosity of acrylic oligomers and are used as a reactive diluent to improve the adhesiveness, heat-resistance, hardness, and curing of acrylic oligomers.
  • Urethane Acrylates: This type has urethane bonding as its major chain, so its coating film is very tough. It has good adhesiveness with various materials.
  • Polyester Acrylates: This type has ester bonding as its major chain and two or more acrylic unsaturated bonds in its molecule. It is easily liquidized at lower viscosities than other acrylic oligomers and has good compatibility with other polymers or oligomers.

Various curing methods are available by using these features of Aronix®. Moreover, hard to soft types can be designed for different uses and functions by bonding various molecules.
