UV Performance Aesthetic Performance Brightness Chalk Resistance Color (Mass tone / Tint Tone) Color Change Gloss Gloss Retention Moisture Content (Lacing) Absorption / Reflection Maintain Product Appearance Enhance Product Appearance Process Performance Dispersion Efficiency in use Improve Productivity Equipment Wear Pigments division TiO2 Surface treatment titanium dioxide inorganic coating (1 - 15%) Crystal doping (e.g. Al) Al2O3 SiO2 (‘fluffy’ or ‘dense’) ZrO2 [Hydrous TiO2] [P2O5] organic treatment (< 1%) Pigment coatings need to be: Colorless Stable Non-toxic Pigments division Inorganic treatment summary Alumina ► ► ► Silica (fluffy) ► ► significantly improves dispersibility aids dispersion stability minimal durability increase improves dispersibility (particularly water-borne) significantly increases opacity in high p.v.c. systems Silica (dense) ► ► improves dispersibility (particularly water-borne) significantly increases opacity in high p.v.c. systems Zirconia ► significantly increases durability Hydrous TiO2 ► improves coatings adhesions & durability Phosphate ► Added prior to wet milling – improves dispersibility Pigments division Organic treatment summary Usually polyols or amines Silicone derivatives Patented organics ► ► Aid in milling during TiO2 production Improves dispersion in applications ► Create a hydrophobic surface for plastic applications (also suitable for powder coatings) ► Improve compatibility with resins and plastics e.g. Silanes, Phosphonylated organics. Can act as lubricant to improve processability Pigments division Fine crystal / Normal crystal ► Fine crystal: ► ~ 0.2µm size gives bluer undertone (small size scatters more blue light) to offset yellow tone of plastics resins. ► Normal crystal: ► ~ 0.25 µm, clean/neutral tone in plastics Pigments division Product offer in Coatings Applications Alumina & Polyol - Designed for easy dispersion in a wide range of applications Less Alumina & Polyol - Excellent thermal stability makes it ideal for high temperature applications (plastics) Alumina, Dense Silica & Polyol - Super durable pigment with excellent processability Alumina, Silica, Zirconia & Polyol Alumina, Silicone Derivatives & Fine Crystal Alumina & Patented Organics - Super durable pigment with excellent optics and higher tinting strength - Excellent color and good dispersion make it work well in most application areas - Low volatiles and excellent dispersion make it exceptional for high performance masterbatch and film Pigments division Product selection: Coatings How to select the right pigment in Coatings Applications! Coating Grades: A-HR, R-XL, TR60, TR90, TR93 Does the customer need a specialty flat grade? Yes No R-XL What is the required level of natural durability?

They do not disperse the pigment! Dispersion occurs when a pigment agglomerate is in contact with the flat part of the spinning blade. This is why tip speed velocity is important, and why smaller blades must turn faster to achieve the same level of shear. 0.6d Impeller rim velocity 2d Impeller speed (r.p.m.) 2.8d Pigments division Criteria to Selecting Wetting and Dispersing Additives for TiO2 • Resin System Aqueous Non-Aqueous Basic (Al2O3) • TiO2 Surface Treatment Neutral (Al2O3 / SiO2) Acidic (SiO2) Low Molecular Weight • Performance Requirement High Molecular Weight Universal, Specialty, or Low Cost Courtesy of BYK Chemie Pigments division Stabilization of TiO2 with Various Alumina Treatments Gloss 20º 95 Al2O3 Dispersant B Dispersant A 90 85 Dispersant C 80 75 70 0 1 2 3 Dosage s.o.p.[%] Courtesy of BYK Chemie Pigments division Dispersants for Alumina Treated TiO2 ► For alumina & alumina / zirconia coated (basic surface) TiO2 ► Acid functional resins & acidic disperants give best dispersion ►Dispersant B ► Dispersants with both acidic and basic groups are also acceptable ►Dispersant A Courtesy of BYK Chemie Pigments division Stabilization of TiO2 with Alumina and Silica Surface Treatments Gloss 20º 92 Al2O3 /SiO2 90 Dispersant A 88 86 84 Dispersant B Dispersant C 82 80 78 0 1 2 3 Dosage s.o.p.[%] Courtesy of BYK Chemie Pigments division Dispersants for Alumina/Silica Treated TiO2 ► For TiO2 coated with alumina (basic surface) and silica (acidic surface) in roughly equal proportions ► Dispersants containing both acidic and basic groups work best ►Dispersant A Courtesy of BYK Chemie Pigments division Stabilization of TiO2 with Silica Surface Treatments Gloss 20º SiO2 Dispersant C Dispersant A Dispersant B 0 1 2 100 90 80 70 60 50 40 30 20 10 0 3 Dosage s.o.p.[%] Courtesy of BYK Chemie Pigments division Dispersants for Silica Treated TiO2 ► For silica and highly silica coated (acidic surface) TiO2 ► Dispersants containing basic groups work best ►Dispersant C ► Dispersants with both, acidic and basic groups are also acceptable ►Dispersant A Courtesy of BYK Chemie Pigments division Dispersant Summary ► No single additive works in every system ► Dispersants with both, acidic and basic functional groups work best across the whole range of TiO2 grades ► And with most water-based resin systems ► For alumina (basic) coated pigments, use acid functional resins & dispersants. ► For highly silica coated pigments, use basic functional resins & dispersants for best dispersion REMEMBER: Opposites Attract Pigments division Conclusions ► Select the right TiO2 product based on the application requirements ► Select the right dispersant based on the pigment ► Use the correct geometry. Equipment / dispersion optimization work via a Six sigma process may yield some savings depending upon the current level of performance, and changes required to improve.
