Product Overview



OTTOPOL CATIONIC RESIN:

INSOLUBLE IN ALKALI
Ottopol K-21 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 effected 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-21 is a resin solution containing a 2:1 ratio of water and IPA, yielding lower viscosity and higher solids. Ottopol K-362 is a
resin solution in water. The dry resin of these cationic resins are identical, including their specific characteristics.
