Product Highlights

INSOLUBLE IN ALKALI

  • Ottopol K-21-30 and K-362 are Low molecular weight cationic acrylic resin solutions. It is suitable for use as a grinding vehicle for organic and inorganic pigments. Pigment concentrates can be let down with these resins to produce printing inks and coatings. A clear coating or overlay varnish may be formulated as well.

 

ALKALI RESISTANCE

  • The dry resin is impermeable to alkali without the use of crosslinking agents. Inks and overlay varnishes for soap boxes and household paper towels will not be affected by the high pH of the detergent cleaner used with the paper towels.

 

ADHESION TO SUBSTRATES

  • Their positive charge allows inks and coatings to have exceptionally good adhesion to plastic films: Mylar, PVC, and polystyrene. Adhesion to foil and other metallic surfaces is excellent.

 

DYE INKS

  • Both products are effective solubilizers for oil soluble dyes and are compatible with basic dyes.
  • Ottopol K-362 is a resin solution in water.
