Recommended coating conditions

  • Solvent: water or water/alcohol (e.g. water/ethanol with ethanol 50wt% or less)
  • Solution concentration: 5-15% (according to coating equipment, desired coat thickness and line speed)
  • Drying temperature: 70-120oC

In order to assure adhesion, we recommend the use of substrate film that has undergone corona treatment.

In addition, use of an anchor coating agent is also effective to enhance wetting and adhesion.
