Usage examples

Usage example 1.

  • 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.
Example of how to create a highly hydrophilic functional coating using our products

Example of composition of Coat A

Name of raw material Compounding ratio (wt%)
Water soluble crosslinking agent (FOM-03006) 30
Water soluble monomer (FOM-03010) 67
Water soluble light radical initiator (FOM-03011) 3
Methanol 400

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)

Coats evaluated Water contact angle (°)
PET alone 75
Coat A 35
Impregnate Coat A with water and dry 44

In evaluation of wettability by water contact angle showing affinity with water, Coat A exhibits high hydrophilicity with a low contact angle, and maintains the hydrophilicity even when it is re-dried after being impregnated with water.

Usage example 2.

  • By replacing a commercially available polyfunctional acrylic monomer with FOM-03006, a coating film less likely to curl with less cure shrinkage can be formed.
