  1. A better alternative to natural mica in the production of effect pigments SYNTHETIC MICA Presented on behalf of Impact Colors, Inc. 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  2. Traditional Effect Pigments Since commercialization in the 1970s, manufactured fromnatural mica coated withone or more layers of metal oxides. Indian ruby mica has been favored for this application. 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  3. Global Consumption Natural mica sheet used as substratefor pearlescent pigment: Global estimate :100,000 to 120,000 tons per year 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  4. Why Synthetic Mica? • At present, 95% of natural mica is imported from India. • Quality is declining and prices are increasing. • Natural mica has deficiencies which are a barrier to development and production of high quality pearlescent pigment. • Development of synthetic mica as a replacement for natural mica lessens the reliance on a decreasing natural resource and lifts the quality of the product type 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  5. What is Synthetic Mica? • Potassium Magnesium Aluminum FluoroSilicate • KMg3AlSi3O10F2 : Synthetic Fluorophlogopite • First synthesized in 1919 • Developed for the electronics industry 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  6. Product development challenges Key Technology Difficulties Innovation • High Temperature • Precise control of composition • Controlled cooling • Delamination and grinding • Process design and formulation • Process scale to 10,000 TPA • Physical processing of mass to single sheet flake – new grinding techniques employed • Determining the parameters that give optimal crystal growth • Conversion of the crystal mass into flake substrate suitable for producing effect pigment 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  7. Bulk density ≤0.35 g/cm3 • Hue: better that standard sample of natural mica • Brightness: better than standard sample of natural mica • PH value: 6-8 • Oil absorption: 60-90 Performance Parameters 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  8. Synthetic Mica vs Natural Mica 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  9. Performance Parameters 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com

  10. Summary of Benefits • Higher purity • More consistency • Cleaner, whiter white pearls • Resistance to higher temperature • Greater reflectivity • Interference colors with higher chroma • More compressible in pressed powders • Less bleed from metallic colors • A better value proposition Compared to natural mica, synthetic mica offers: 1 Innovation Way, Ste.100 Newark, DE 19711 T:302-224-8310 www.impactcolorsinc.com
