16 How to bring Spatter Resistance & Contribute to the Leveling NATROSOL PLUS 330 PA 16

17 Natrosol Plus 330 = HMHEC Oxy-ethylene Cellulose Alkyl Hydroxyethyl 17

18 Thickening mechanism Natrosol Plus 330 HMHEC Thickening mechanism Hydrohobe Latex particle Hydrogen bonds 18

19 Latex type effects Latex Chemistry Vinyl Acrylic VA- VeoVa VAE Acrylic Alkyd Emulsion Styrene Acrylic Increasing Hydrophobicity 19

20 Rheology Options for Paints & Coatings High performance HMHEC rheology additives HEC Natrosol Plus 330 PA 20

21 Spatter collected after application of a paint made with Natrosol Plus 330 PA Spatter collected after application of a paint made with Natrosol 250 H4BR 21

22 Natrosol Plus 330 Outstanding spatter resistance Improved leveling Improved brushing viscosity A High Quality Cellulose Ether for your High Quality Paint 22

24 Kennedy, Texas Aquaflow plant 24

25 Structure of Aquaflow N-Series Hydrophilic Hydrophobic Hydrophobic = Alkyl Chain 25

26 Associative Thickening of Aquaflow Paint Latex 26

27 Latex type effects Latex Chemistry Vinyl Acrylic VA- VeoVa VAE Acrylic Alkyd Emulsion Styrene Acrylic Increasing Hydrophobicity 27

28 Difference between Aquaflow and HEUR : ph stability Viscosity retention of 4 % solutions after 21 days at 25 C ention % viscosity ret HEUR Aquaflow ph of solution 28

29 Position of Aquaflow vs HEUR Performance More predictable Viscosity Response Less ph, Electrolyte Sensitive Improved Color Acceptance Improved Viscosity Change On Tinting Aquaflow HEUR Economic Advantage 29

30 Xceptional Leveling & Sag-resistance Sag Resistance Leveling Viscosity Retention upon Tinting (VRT) Aquaflow XLS-500 Aquaflow XLS-525 Conventional NSAT s Low as is supplied viscosity 1200 mpa.s 1600 mpa.s mpa.s 30

31 Balance sag resistance & leveling VRT TE Low as-is viscosity Aquaflow XLS-series value : Sag Resistance Compet LS-NSAT / Compet HS-NSAT * Aquaflow XLS-500/NHS-300 * HS-NSATs = high shear non ionic synthetic associative thickener 31

32 Balance sag resistance & leveling VRT TE Low as-is viscosity Aquaflow XLS-series value : Leveling High gloss top coat based on alkyd emulsion PVC 18 32

33 Balance sag resistance & leveling VRT TE Low as-is viscosity Aquaflow XLS-series value : Viscosity Retention on Tinting (VRT) Example 1 : Viscosity Retention upon tinting in a Deep Tone base paint, PVC 43%, based on Styrene Acrylic binder Acronal S 559. Paint viscosity loss measured after 5 wt% tinting paste orange, red and blue added : 5 Stormer viscosity loss after tint ting (KU) Aquaflow XLS-500 Aquaflow XLS-525 Compet 1 Compet 2 Compet

34 Outstanding Combination Natrosol Plus 330 & Aquaflow Spatter resistance Leveling, color acceptance 34
