Nanotechnology Latex Replacement
6. Freight savings7. Provides flexibility for formulation
development8. Energy and labor savings
6. Available in dry powder form7. Available as liquid
dispersion8. Requires no cooking
1. Significant annual savings2. Price stability, since not linked to rising
petroleum prices3. Similar performance in coating colors4. Lab results show more effective binder
with several improved properties5. Simple adjustment of existing coating
recipe – similar runnability
1. Lower latex cost2. Renewable resource based
(chemically modified starch)3. Substitute for SBR latex4. Smaller particle size 80-120
nm (SBR 150-400 nm)5. Viscosity & ultra-high shear
rheology similar to SBR

Value Proposition
• Priced below your current SBR price• Price stability – not tied to price of petrochemical
feedstocks• Based on pilot plant data 25% to 75% of SBR latex
volume can be replaced with the ECOSPHERE®
product while maintaining product quality• Preliminary results indicate added performance:
– Increased bending stiffness– Increased CIE Whiteness– Improvement in water retention performance– Increase in IGT dry pick
