Nichigo-POLYESTER™

Amorphous Solvent-soluble Type

These are polyester resins that dissolve easily in methyl ethyl ketone, toluene, and other organic solvents. They display excellent adhesive performance with plastic films and moldings including PET, polycarbonate, and vinyl chloride, and metals including alminum and copper. Used in tandem with isocyanate, melamine, and epoxy resins and other hardening agents, they offer increased heat resistance, solvent resistance, and hardness.

  • Frexible printed circuit boards
  • can coatings
  • magnetic coatings
  • coatings for precoated metals
  • ink binders
  • dry lamination adhesives
  • film surface modification agents
  • coatings for recording papers
