Ottopol K-23 Features & Benefits

Adhesion to Dfficult Substrates

  • Positive charge allows inks and coatings made with Ottopol K-23 to have exceptionally good adhesion to plastic films; Polyethylene, PVC, Polyester, and Polystyrene.
Product Attributes
  • It is designed for use as a grinding and letdown vehicle for waterbased flexographic and rotogravure inks.
  • It is also suitable for use as an overprint varnish.
  • The emulsion characteristics provide higher solids and better gloss.
