2 DISPERSING PROCESS OF PIGMENTS
1) WETTING L/S INTERFACE--S/G INTERFACE 2) DEAGGLOMERATION BREAKAGE & REAGGLOMERATION 3) STABILIZATION REMAINING PARTICLE SIZE & ITS DISTRIBUTION

3 MECHANISM OF DISPERSION STABILIZATION
ELECTROSTATIC STABILIZATION DOUBLE--LAYER THEORY STERIC STABILIZATION OSMOTIC REPULSION THEORY ENTROPIC REPULSION THEORY

4 DEEFFICIENCY OF CLASSICAL SURFACTANTS

11 RHEOLOGICAL PROPERTIES OF THE
DISPERSION WITH HYPERDISPERSANT Viscosity-reducing properties Viscosity-reducing properties Influence of anchoring group Influence of solvatable chain

12 STABILIZATION PROPERTIES OF THE DISPERSION WITH HYPERDISPERSANT
Deposition curve of magnetic dispersion Viscosity stability of the ink with hyperdispersant

13 METHOD OF USE OF HYPERDISPERSANTS
MINIMAL RESIN REDUCED RESIN SOLIDS--LOWERED VISCOSITY & STABILITY ADDING HYPERDISPERSANT IMPROVED STABILITY FURTHER REDUCED VISCOSITY IMPROVING PIGMENT CONTENT HIGH PIGMENT / VEHICLE RATIO HIGH STABILITY, NORMAL VISCOSITY

14 NOTATION FOR USE OF HYPERDISPERSANT
ADDED BEFORE PIGMENTS, FILLERS AND OTHER INGREDIENTS ADDING SURFACTANTS DURING LET-DOWN OR LATER STAGES DOSAGE DEPENDS ON SURFACE AREA(ABOUT 2MG/M2)

15 ADVANTAGES OF HYPERDISPERSANTS
FAST WETTING, SHORTER MILLING TIME, IMPROVED PRODUCTIVITY HIGH PIGMENT / VEHICLE RATIO, LESS ENERGY AND LABOUR COST REDUCED VISCOSITY, IMPROVED RHEOLOGICAL PROPERTIES IMPROVED DISPERSING STABILITY, IN AVOID OF RE-DISPERSION

16 ADVANTAGES OF HYPERDISPERSANTS
WIDE COMPATIBILITY OF MILLBASE NOT EASY TO BE OXIDIZED, LESS SURFACE WASTAGE PRODUCED HYDROPHOBIC DISPERSANTS NO HYDROPILIC FILM INDUCED COMPLETE WETTING AND BETTER APPLICATION QUALITIES

19 OFFSET INK APPLICATION
HYPERDISPERSANT OFFSET INK APPLICATION

20 BENEFITS IMPROVED QUALITY HIGHER GLOSS GREATER INTENSITY MORE TRANSPARENCY HIGHER PRODUCTIVITY SHORTER DISPERSION TIMES HIGHER PIGMENT CONTENT

21 BENEFITS MORE FLEXIBILITY
MORE VERSATILE MILLBASE HEATSET AND SHEETFET FROM SAME MILLBASE MORE STABLE CONCENTRATES ABILITY TO TRANSPORT

22 HYPERDISPERSANT FOR OFFSET INKS
HYPERDISPERSANT SELECTION FOR LITHOL RUBINE / RUBINE TONER USE CH-5 ONLY FOR PHTHALOCYANINE BLUE OR CARBON BLACK USE CH-5 + CH-11B FOR DIARYLIDE YELLOW USE CH-5 + CH-22

23 TYPICAL DOSAGE (SHOWN AS WEIGHT OF PIGMENT) RUBINE-------8%----CH-5
BLUE %----3:1 CH-5:CH-11B YELLOW---10%---3:1 CH-5:CH-22 BLACK %--10% CH (DEPENDS ON THE SPECIAL SURFACE OF CARBON BLACK)

24 GUIDELINES FOR USE REDUCING RESIN SOLID TO 30-40% IN MILLBASE
HOLD BACK IN MILLBASE AS MUCH AS POSSIBLE GELLED VEHICLE OR GELLING AGENT ADDING HIGHER PROPORTIONS OF GELLED VEHICLE / GELLING AGENT AT THE LET-DOWN STAGE TO COMPENSATE
