Water-soluble Type

Containing no alcohols or other solvents, these are high-stability, entirely water-based polyester resins. They are highly regarded as surface modification agents for the modification of wettability in PET films and the improvement of adhesion.

Applications & Characteristics

  • Film surface treatment agents
  • fiber treatment agents
  • steel sheet treatment agents
  • coatings for recording papers
