WinSperse 5291

Pigment modifier for solvent based applications

　Chemical composition

　General application guidance

　Use 5-15% on dry pigment basis.

　Add 2 part of Winsperse 5291 and 1　part of acetic acid to 20X hot water　to dissolve. Can be used before or　after the coupling solution. After the　pigment paste heated to 90 degrees,adjust the pH=11.

　Chemo-physical Properties

　Package

　Appearance: white to yellowish paste　or solid

　Active ingredient: 100%

　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.
