     For use in red azo-pigments.Add to the rosin solution.

     Characteristics

     Package

     Especially suitable to improve dispersibilty of red azo-lake pigments in offset ink for a more vibrant color with much reduced viscosity and better storage

    stability.

     Can also be used in improving color strength and viscosity for yellow azo-pigments such as P.Y.12, P.Y.174.

     Drum: 18kg/drum

     Application scope

     Storage

     Such treated pigments such as P.R.53:1, P.R.57:1, P.Y.12, P.Y.174 are used in offset inks and low polarity solvent inks.

     Store in cool and dry places,good for 2 year.

     After partial use, re-seal the container.
