    Learn about Spacer Technology.

    Spacer Technology revolutionizes pearlescent pigments.

    What is Spacer Technology?

    Spacer Technology introduces a unique layer of periodic nano cavities within the pigment structure.

    These cavities act as spacers, significantly enhancing optical properties by creating an effective low-refractive index layer.

    This innovation allows for superior light interaction and unmatched reflectivity.

    Technical Highlights:

    • Nano Cavity Spacers: Structurally verified via SEM and STEM analyses, spacer layers range from 2 to 119 nm in height.
    • Optimized Light Reflection: The low refractive index of the spacer layer (below 1.3) boosts reflectivity and color brilliance.
    • High-Refractive Metal Oxides: Utilize Ti, Fe, Sn, Mn, Zr, and Zn oxides for advanced optical effects.

    Superior Optical Performance.

    Key Benefits of Spacer Technology:

    • Higher Chroma and Sparkle: Achieve 30-60% greater color intensity compared to conventional pigments.
    • Angle-Dependent Effects: Enhanced flop behavior and anti-fading effects provide consistent, vibrant colors across viewing angles.
    • Anti-Fading Properties: Rich, deep colors that maintain brilliance even at extreme angles.

    Benchmark Results:

    • Reflectivity Gain: 10-30% increase in reflectivity compared to traditional interference pigments.
    • Color Consistency: Minimal change in color shade across angles, ensuring reliable performance.

    Explore Spacer Technology Products:

    • Edelstein Series: Vibrant, high-chroma pearlescent pigments such as Sapphire Blue, offering deep blues and outstanding flop effects.
    • Luxan Series: Exceptional sparkle and luster for premium formulations, with superior chemical and UV stability.

    Unmatched Stability and Versatility

    Spacer-type pigments are designed to withstand the most demanding applications:

    • Chemical Resistance: Exceptional stability in aggressive environments (acids, bases, solvents).
    • UV Durability: Ideal for outdoor applications such as OEM coatings and powder coatings.
    • Mechanical Stability: Superior shear resistance, ensuring reliable performance during processing.
