Difference between Aquaflow and HEUR : ph stability Viscosity retention of 4 % solutions after 21 days at 25 C ention % viscosity ret 100 80 60 40 20 0 12 11 10 9 8 7 6 5 4 3 2 HEUR Aquaflow ph of solution 28
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
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 2000-5000 mpa.s 30
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
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
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) 0-5 -10-15 -20-25 Aquaflow XLS-500 Aquaflow XLS-525 Compet 1 Compet 2 Compet 3-30 33
