Microcapsule

Micro capsule is an essential raw material in NCR production especially for the CB (coated back) and CFB (coated front and back) of the NCR paper layers.
Micro capsule slurry is coated to the NCR base paper as color former. When the capsule wall breaks due to writing pressure, it reacts to a typical resin such as the active clay, phenolic resin and zinc salicylate to form colored image.
Type of capsule wall are:
  • Iso Cyanate
  • Melamine Form Aldehyde
  • Gelatin
