APPLICATIONS

KAMICRYL-2090 is a non film forming emulsion developed for use in water based overprint varnishes and flexographic and gravure inks, providing high heat seal and film release properties. The heat resistant properties may be further enhanced by the addition of Zinc Ammonium Carbonate solution. In overprint varnishes KAMICRYL-2090 additionally provides gloss and optical clarity.

    KAMICRYL 6550

    KAMICRYL 6550 is a water based acidic colloidal emulsion which can be easily solubilized with Alkali for use in ink for pre-print & post-print corrugated paper & board applications.

    Typical Properties
    Type : acrylic dispersion
    Appearance : Whitish , bluish
    Total solids (% w/w) : 42%± 1
    pH (25°C) : 2.0-3.0
    Acid value : 165
    Molecular weight : 55,000 to 60,000
    Viscosity, B4 cup : 14-16 seconds
    Density, g/cc, (25ºC) : 1.05
    Density of dipsersion (kg/l) : 1.065

    Properties:

  • Good Grinding medium
  • Good print & transfer properties
  • Good hot mar resistance
  • Good transfer properties

    • Recommendation for end-use:

  • For corrugated paper & boards
  • Good let dowm Vehicle
  • Good grinding properties
  • Economical cost

    • General Guidelines:

    Kamicryl 6550 is a high solid acidic dispersion and should be reduced to a lower solids with water to about 20-25 % and can easily be solubilized with ammonia or any alkali prior to use. The solubilization with alkali is complete at an approximate pH 7.5 to 7.7.

    At about pH 9.0-9.2 can be achieved a peak and stable viscosity by careful selection of final solid content and pH.

    Kamicryl 6550 may be solubilized and used as a grinding medium and letdown vehicle.
