     Characteristics

     Storage

     This  product  has  multiple anchoring points for the pigment surfaces; the long chains of this polymer provide special stabilization for the dispersed pigment particles.

     Such modified pigments have great solvent resistance and anti-coagulation,  thus  have improved color strength, gloss, viscosity and storage stability.

     Especially suitable for yellow pigments used in toluene ink.

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

     After partial use, re-seal the container.


     Application scope


     Mainly used to modify yellow azo-pigments such as: P.Y.12,P.Y.14,especially P.Y.12.

     When used on P.Y.14, the pigment  can  be  used  in

    nitrocellulose, benzene-soluble poly amide systems with better gloss and viscosity.
