Opacity as well as properties such as stain and dirt pickup resistance and wash-ability are typically valued. 14 7

The Use of TiO2-Polymer Composites to Lower Environmental Impact and Improve Performance of Waterborne Paints, Paintistanbul 2012, September. 19 Audience Challenge Question ANSWER THE QUESTION ON BLUE SCREEN IN ONE MOMENT Why is titanium dioxide used in paints? Provides texture to surface and control gloss Its high refractive index yields light scattering and opacity Stabilizes coating against UV degradation Its hardness provides abrasion resistance All of the above 10

11 Light Scattering is a Critical Property For Many Coatings Light Absorption Light Scattering Material Refractive Index TiO ZnO 2.0 Extender Air 1.0 Polymer Optimal Light Scattering Refractive Index Differences Pigment Particle Size Pigment Dispersion Quality Surface Paint Film Substrate 21 Light Scattering is a Critical Property For Many Coatings Light Absorption Light Scattering Material Refractive Index TiO ZnO 2.0 Extender Air 1.0 Polymer Optimal Light Scattering Refractive Index Differences Pigment Particle Size Pigment Dispersion Quality Powdered Sugar < 0.1 mm Granulated Sugar ~ 0.5 mm Surface Paint Film Substrate Rock Candy > 5 mm 22 11

12 TiO 2 is the Best Pigment for Light Scattering But it has a Deficiency TiO 2 is the primary white pigment in paint. It scatters light and provides hiding. Inefficiencies of TiO 2 In a typical paint, TiO 2 distribution is worse than random. As paint film dries, crowding occurs and creates regions of high and low concentration. In areas of high concentration, light scattering zones overlap and create inefficiency. 23 Technology Evolution Dispersion Stability TAMOL Dispersant circa. 1950s Polymeric Pigment ROPAQUE Opaque Polymer 1980 Pigment Efficiency EVOQUE Pre-Composite Polymer 2012 Developing enabling technology for pigment efficiency Technology For Improving Pigment Efficiency 24 12

13 Opaque Polymer-Replacing Pigment with Air Synthetic pigment - not a binder Opacifying pigment, scattering by the air void upon drying Partially replaces TiO2 as white pigment Polymer Efficient Scattering Refractive Index Difference Polymer WET Air Void (dry) (full of water) DRY Air Void (dry) psty H2O n=1.60 n=1.33 psty Air n=1.60 n=1.00 EVOQUE Pre-Composite Polymer is a Hiding Breakthrough TiO 2 Only TiO 2 + Precomposite Polymer TiO 2 Only TiO 2 + Precomposite Polymer TiO 2 Only TiO 2 + Precomposite Polymer Adsorbing latex would self assemble to form discrete pigment polymer composites Complements improvements existing from opaque polymers & dispersants Benefits are additive 26 13

14 Audience Challenge Question ANSWER THE QUESTION ON BLUE SCREEN IN ONE MOMENT How hard could that be what could go wrong? A) The interaction between the pigment and polymer could be too aggressive, resulting in destabilization of the paint B) The interaction between the pigment and polymer could be too weak, resulting in ineffective and / or incomplete composite formation C) The higher mass resulting from the composite formation (i.e., latex + pigment) could exceed the stabilization of the latex system, resulting in agglomeration over time D) All of the above Balancing Reactivity Adsorbing Latex TiO 2 Surface Treatment (Al/Si) No Adsorption Composites Agglomerates Grit 28 14

15 Uniform TiO 2 Distribution SEM of Regular Paint SEM of Composite Paint Brighter spots indicate TiO 2 is above the surface More uniform distribution of TiO 2 Surface of polymer Higher Performance at equal cost or equal performance at lower cost 29 Film Distribution Conventional TiO 2 Paint TiO 2 - Polymer Composite Paint 3-D SEM Micrographs - Film 30 15

17 Audience Challenge Question ANSWER THE QUESTION ON BLUE SCREEN IN ONE MOMENT Why do exterior paints look chalky over time? A) UV light crosslinks the binder resulting in the pigment particles being squeezed-out of the bulk film B) The binder erodes over time, increasing the local concentration of pigment and simultaneously resulting in those pigment particles being unbound in the bulk film C) Dirt and other material collects on the surface D) The refractive index of the pigment changes the longer it is exposed outside E) All of the above Photooxidation of (Meth)acrylates and Film Degradation UV damage affected by: 1) Pigment (type, size, flocculation, absorption/scattering) 2) Angle of incidence, wavelength 3) Water and oxygen penetration 4) Other factors Weathering of exterior paints is strongly impacted by oxidative degradation of polymer chains and subsequent polymer erosion, leaving a surface enriched in unbound inorganic particles (chalking). For most systems, a gloss decrease is noted before chalking is observed during both natural and accelerated weathering. The loss of gloss is due to a roughening of the paint surface. O.

18 Photooxidation of (Meth)acrylates and Film Degradation O. Chiantore, Photooxidative degredation of acrylic and methacrylic polymers, DOW RESTRICTED Polymer 41 (2000) Polymer Composites Improve Exterior Durability In general, a paint predicated on TiO 2 -Polymer composite technology has better exterior durability (Gloss Retention and Tint Retention) relative to their non-composite analogues Several theories as to why. Cause Lower levels of TiO 2 Better distribution of TiO 2 Binder-rich layer on the surface Effect Less radicals generated Protects the bulk film Protects the bulk film Forms a tighter film Less permeable to H 2 O and O 2 TiO 2 is encased in polymer Minimizes H 2 O and O 2 from interacting with TiO 2 ; Captures radicals 36 18
