Patinal® Substance H2

Patinal® Substance H2 by Merck KGaA, Darmstadt Germany is an evaporation material. It is a titanium zirconium oxide mixture for high refractive index thin films. It offers high purity, low spitting and high batch-to-batch consistency. When the material melts, it evaporates more easily than ZrO₂, forming very homogenous layers without a refractive index gradient.

• It is recommended for optical and functional coatings.
• It is mainly used in (AR) anti-reflective and other multilayer coatings in the visible spectroscopy (VIS) and near-infrared (NIR) spectral range.
• Patinal® Substance H2 is used in coatings on plastic substrates.
