  1. CH HYPERDISPERSANT STRUCTURE & PRORERTIES SHANGHAI SANZHENG POLYMER MATERIAL Co.,LTD

  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 • HYDROPHILIC GROUP NOT DESIGNED FOR PIGMENT SURFACE, EASY TO DESORB • HYDROPHOBIC GROUP NON-POLAR STRUCTURE INCOMPATIBLE WITH POLAR MEDIA 18 CARBON ATOMS, TOO SHORT

  5. Anchoring Group PARTICLE PARTICLE Solvatable Chain MOLECULAR STRUCTURE OF CH HYPERDISPERSANTS

  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. 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---------10%----3:1 CH-5:CH-11B • YELLOW---10%---3:1 CH-5:CH-22 • BLACK------4%--10% CH-5 (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
