1. Overcome Cellulosics Drawbacks with Rheotech™ x800

2. Agenda What is currently known about HEC and HASE thickeners :
strengths and weaknesses
Case studies addressing HEC and HASE known weaknesses
thanks to new HASE technologies

3. HEC thickeners use and performance
Stable viscosities for shelf life stability
Robustness vs binder technology
Color compatibility, homogeneous appearance to tinted paints
Open time to thin and thick paint coatings
Powder form, preparation time more water amount and swelling time
Poor leveling, addition of glycol or HEUR thickeners
Spatter issues and limited brush drag/film build due to poor high shear building
Limited choice of rheology profiles
Case 3
Case 1

4. HASE thickeners use and performance
Case 2
A broad spectrum of rheology profiles, from Newtonian to pseudo plastic
Better productivity, liquid form, no preparation, incorporation at any stage, post-addition
Remarkable application properties thanks to the control of high shear rate viscosities
Better price/performance ratio: less use of thickener leading to cost savings
Dependant on binder technology
Significant viscosity evolution overnight and in time for 0-VOC paints
Open time reduction of thin and thick paint coatings

8. Dependency of HASE on binder technology
Case 2
Aim: to maintain rheological balance while choosing another latex chemistry and/or changing its amount in a Matt Paint Formulation
Low Shear Viscosity  mPa.s (Brookfield at 10 rpm)
Medium Shear Viscosity  120 KU
High Shear Viscosity  1.1 P (ICI viscosity)
Three different latexes Two dosages
Styrene Acrylic 1 5 % & 15 % of latex
Styrene Acrylic % & 15 % of latex
Ethylene Vinyl Acetate 15 % of latex
Results
Difference between the obtained and targeted values is calculated in %.
Target is considered as achieved each time the difference is less than plus or minus 30%.
