FOM-03011
Water soluble light radical initiator
Plastics manufacturing
Photocurable
FOM-03011 is an initiator with excellent water solubility developed by using Fujifilm's proprietary technology. The degree of freedom of the addition amount increases for aqueous components, thereby achieving high curability.
In addition, it is liquid and easy to handle, and has low odor, low volatility and excellent storage stability. It is soluble in many organic solvents other than water.

2) Liquid
- FOM-03011 is liquid and easy to handle, and has an excellent workability.
- The solid does not precipitate, and thus the product can be delivered stably.
- It is liquid that has a high heat resistance.
3) Low odor/low volatility
- It has low odor and low volatility, and thus improves the working environment.
Applications
Initiator for water-based curing material
Examples:Film, adhesives, pressure sensitive adhesives, ink, electrolyte gel, medical hydrogel, paint
Initiator for various coatings
Examples:Film, optical materials, recording materials, electronic materials
Usage example
- A functional coat with a high hydrophilicity can be formed.
- Due to the high water solubility of the monomer and initiator, a coat solution can be prepared using water as a solvent.

Usage example and physical characteristics of Coat A
- Apply to PET substrate, dry (50°C/5 min), and then photocure (3 J/cm2)
※Lamp used: High pressure mercury lamp (Exposure is controlled as UV-A)
