Traditional Effect Pigments

Since commercialization in the 1970s, manufactured from natural mica coated with one or more layers of metal oxides. Indian ruby mica has been favored for this application.

Global Consumption

Natural mica sheet used as substrate for pearlescent pigment:Global estimate :100,000 to 120,000 tons per year

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

•High Temperature

•Precise control of composition

•Controlled cooling

•Delamination and grinding

Key Technology Difficulties Innovation

• Determining the parameters that give optimal crystal growth

• Conversion of the crystal mass into flake substrate suitable for producing effect pigment

• Process design and formulation

• Process scale to 10,000 TPA

• Physical processing of mass to single sheet flake – new grinding techniques employed

Summary of Benefits

Compared to natural mica, synthetic mica offers:

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
