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

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

4 DEEFFICIENCY OF CLASSICAL SURFACTANTS s HYDROPHILIC GROUP NOT DESIGNED FOR PIGMENT SURFACE, EASY TO DESORB s HYDROPHOBIC GROUP NON-POLAR STRUCTURE INCOMPATIBLE WITH POLAR MEDIA 18 CARBON ATOMS, TOO SHORT

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

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 s MINIMAL RESIN REDUCED RESIN SOLIDS--LOWERED VISCOSITY & STABILITY s ADDING HYPERDISPERSANT IMPROVED STABILITY FURTHER REDUCED VISCOSITY s IMPROVING PIGMENT CONTENT HIGH PIGMENT / VEHICLE RATIO HIGH STABILITY, NORMAL VISCOSITY

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

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

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

19 HYPERDISPERSANT OFFSET INK APPLICATION

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

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

22 HYPERDISPERSANT FOR OFFSET INKS l 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 l (SHOWN AS WEIGHT OF PIGMENT) ¶ RUBINE-------8%----CH-5 · BLUE---------10%----3:1 CH-5:CH-11B ¸ YELLOW---10%---3:1 CH-5:CH-22 ¹ BLACK------4%--10% CH-5 (DEPENDS ON THE SPECIAL SURFACE OF CARBON BLACK)

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